Eugene Perelshteyn Teaches the English!

For our first Chess^Summit guest author, we are very excited to introduce Grandmaster Eugene Perelshteyn! In today’s video, GM Perelshteyn shares a recent game he played in the English Opening against a strong player where he won using positional concepts. This is a great resource for players who play the English, but also for those that play the Hyper-Accelerated Sicilian as recommended by Perelyshteyn’s book Chess Openings for Black, Explained. While the opening seemed unambitious, White was able to quickly able to expand on the queenside and create a potential passed pawn as discussed in the video!

Make sure to check in next week, as our authors Beilin Li and Vishal Kobla introduce themselves to Chess^Summit and discuss their goals for the upcoming year. Have a great Independence Day weekend!

Chess Chat 3 – Free Game Analysis and Other Big News

My coach told me to relax this week and limit my preparation for the Carolinas Classic this weekend, so for today’s  video, I decided to review a free game analysis submission from a few weeks back. Interesting game, important notes on opening fundamentals – don’t miss out!

As I briefly mentioned in my last post, I will be adding new authors to Chess^Summit after the US Junior Open. In today’s video, I take a few minutes to discuss the future of Chess^Summit, as well as reveal one new future author. I have a feeling that regardless of how Chess^Summit 3.0 turns out, I think it will be a fun and exciting project to be a part of.

As always, if you too would like your game to be analyzed, make sure to send your game PGNs to chess.summit@gmail.com, and I’ll try to go over it here on the site – either in article or video form.

That being said, I hope you enjoy today’s video, and make sure to check back next week to hear about my results in Charlotte!

Free Game Analysis: What is Beast Mode?

For today’s Free Game Analysis post, I will be sharing two games from one of the strongest scholastic players in Richmond, Matthew Normansell. Just last month, the high school junior tied for 9th in the U1900 National High School Chess Championships, bringing his rating to an all-time high at 1738. In just the three short years I’ve worked with him, he’s gained 1000 (!) rating points, and is trying to break expert before his graduation next June.

IMG_3163
Matthew (right) taking on rival and teammate Jeffrey Song at the 2015 MLWGS Summer Scholastic.

So in today’s post, not only will we be discussing improvements in each individual game, we will be pinpointing the strengths of Matthew’s play – specifically resourcefulness. While I haven’t worked with Matthew as much this past year, I noticed that his ability to fight in completely lost positions was one of his critical distinguishing traits from the rest of the MLWGS team.

In his freshman year, Matthew earned the nickname “Beast Mode” for his ability to put together a winning attack despite his propensity to hang pieces. I’d say that from my own observation, a majority of the games he won before breaking 1200 were in fact completely lost at some phase of the game. Obviously, to be 1700, you cannot routinely hang pieces, so at some point, the tactical entertainment evolved to positional resuscitation.

I specifically remember a quad last year where he was extremely worse positionally in each game, yet as a 1400, upset an 1800 and drew a 1950. The value of this resourcefulness in chess cannot be understated, and has proven itself to be a vital characteristic of Matthew’s style.

IMG_2156

This past week, I got to analyze Matthew’s games for the first time in months, and I’m rather impressed with how “Beast Mode” has continued to evolve. Rather than waiting to be punished by his opponent, the monster now feeds off his own energy, playing more complete games, much more resembling that of an expert than that of an amateur.

So without further ado, let’s look at the last three rounds of Matthew’s National High School Chess Championship performance in Atlanta.

Yu – Normansell (U1900 National High School Championship, 2016)

1.d4 Nf6 2.c4 e6 3.Nc3 Bb4

Screen Shot 2016-04-23 at 14.30.17

Here on chess^summit, we haven’t had many opportunities to discuss the Nimzo-Indian, however, it is considered one of the most solid openings for Black against 1. d4 and enjoys a vast following. Black gives himself time to decide between a …c7-c5 or a …d7-d5 thrust by opting to castle first.

4.Bg5 h6 5.Bd2?!

Screen Shot 2016-04-23 at 14.35.22

Already White deviates from the main line of the Leningrad System by retreating his bishop here rather than h4 to maintain pressure on the f6 knight. If White was really concerned about structural problems, he should have opted for the 4. Qc2 lines rather than the Leningrad. Now Black enjoys an extra tempo in a flexible position.

5…O-O

Screen Shot 2016-04-23 at 14.45.45

A practical decision. Black could have considered an immediate …c7-c5 push to point out White’s awkward development and loss of time with 5… c5 6. d5 d6 7. Nf3 e5.

Screen Shot 2016-04-23 at 14.53.51

This position emulates the main line of the Leningrad System as proposed by Chess Openings for Black, Explained but also highlights the issue that without a bishop on h4, both of White’s bishops are bad while Black maintains a strong center. While this is promising, Matthew’s choice to castle instead offers a no-nonsense approach to the game. Having lost two consecutive games earlier that day, it was critical for Matthew to find some momentum going into the last day of the competition, so focusing on fundamentals was the right approach.

6.Nf3 d6

Screen Shot 2016-04-23 at 15.10.48

Again, remaining flexible. With White’s slow play, Black is in no rush to take the center. This move offers two plans: …c7-c5, or …Qd8-e7, followed by …e7-e5. Needing to castle, White is presented with an unpleasant decision this move, 7. e3 or 7. Qc2 to prepare e2-e4. White probably chose correctly with 7.e3, but either way, a positional concession had to be made. If White had chosen 7. Qc2, Black could consider a “waiting” move with 7… Qe7 because 8. e4 reaches an unfavorable position with Black’s response 8… e5.

Screen Shot 2016-04-23 at 15.21.12

Objectively, perhaps Black has better moves, but the point is that structurally White has ceded control over the d4 square, and again, the passivity of White’s bishops is a key highlight.

7.e3 =+

Screen Shot 2016-04-23 at 15.23.45

It’s amazing what a loss of tempo can do to a position. But you have to ask, did White play 4. Bg5 just to bring it back and block it in with 7. e3? I didn’t think so…

7…Bxc3

Screen Shot 2016-04-23 at 15.27.24

I’m not a fan of this move. Of course at some point, Black will inevitably trade this bishop for the knight, but it was critical to wait for White to use a tempo and play a2-a3 first. I think Black had a lot of options here, but I like challenging the e4 square the most with 7… b6. After 8. Be2 Bb7 9. 0-0 Nbd7, Black has a lot of options, the most attractive option being putting a knight on e4.

Screen Shot 2016-04-23 at 15.36.57

Now if White uses a tempo to play a2-a3, he loses his last defender of the e4 square, and still has to worry about …e7-e5 and …c7-c5 breaks. If White had tried to stop Black’s pressure on e4 with 8. Bd3, he’ll find how misplaced the bishop on d2 is when Black slaps down 8… Ba6! with the idea of …Nb8-c6-a5. With the real pressure on c4 coming, White also has to worry about his lack of coordination as the bishop on d3 is unprotected.

Screen Shot 2016-04-23 at 15.42.35

Black isn’t winning, but it’s clear that waiting to exchange on c3 gives Black more strategic chances.

8.Bxc3 Ne4 9.Qc2 Nxc3=

Screen Shot 2016-04-23 at 15.46.10

By trading off the dark-squared bishops, White has gotten rid of his bad bishop and has a lead in development. However, with a solid position, Black still holds relative equality. Even though White has space, he doesn’t have a space advantage because of the lack of pieces to apply further pressure. Black will find a thrust and the center and will have reasonable chances to find counterplay.

10.Qxc3 Qe7 11.Bd3

Screen Shot 2016-04-23 at 15.49.25

Based on his next two moves, White’s bishop is misplaced here and belongs on e2. While seemingly unusual, this is also the case in many London System positions to put the bishop on e2 instead of d3. With Black’s recent trades the pace of the game has slowed down, but many of White’s troubles start with this seemingly innocuous decision.

11…Nc6 12.h3 e5 13.Bc2 a5!

Screen Shot 2016-04-23 at 15.57.07

Just like my post on the Maroczy Bind last week, …a7-a5 comes to the rescue again, stopping any queenside expansion ideas.

14.a3 f5 15.d5 Nb8 16.e4? =+

Screen Shot 2016-04-23 at 16.00.40

White seals in his own bishop with this move. With the e4-d5-c4 pawn structure fixed on light squares, White has accepted a bad bishop. To make progress, Black will attempt to exchange his own bishop for the f3 knight, reaching a good knight v bad bishop endgame. Then, by using the dark square strategy, will play to take advantage of White’s passivity.

16…f4 17.O-O-O?

Screen Shot 2016-04-23 at 16.04.17

Simply failing to grasp the troubles of his own position. White needs to undermine Black’s pawns structure to have any chance to equalize and had to at least consider 17. c5.

Screen Shot 2016-04-23 at 16.06.29

It’s not really a pawn sacrifice since if taken, the e5 pawn falls so Black has to consider White’s threat to open the c-file.

Screen Shot 2016-04-23 at 16.09.42

Again, the misplaced bishop presents problems for White, but at least it’s still a game. By queenside castling, White’s king on c1 means that White really cannot afford to open up that side of the board. Let’s see how Matthew takes advantage.

17…Nd7 18.Rdg1 Nc5!

Screen Shot 2016-04-23 at 16.14.58

I really like this move! Black recognized that White really wasn’t threatening anything with this last move, so took the liberty of improving his position while waiting for White to cause more self-harm.

19.g3 Bd7 20.gxf4

Screen Shot 2016-04-23 at 16.16.41

White tries to break the static nature of the position with dynamic play, but in doing so, creates a target for Black. It’s never too early to start thinking about the principle of two weaknesses. Here Black gets his first on the f-file by simply recapturing with the rook, freeing the f8 square for the other. White will now spend more time protecting f2 than actually attacking g7. Furthermore, e4 is hit, and now White must also worry about his general lack of stability.

20…Rxf4 21.Qe3 Qf6 22.Rg3 Rf8

Screen Shot 2016-04-23 at 16.19.38

While the attack Matthew has essayed seems quite simple, getting here required precise positional play and a deep understanding of Nimzo-Indian pawn structures. Having played like an expert thus far, it’s unsurprising that Matthew but away this endgame with relative ease.

23.Nh2 Rxf2 24.Rhg1 Rf7 25.Rg6 Qf4 26.Qxf4 R2xf4

Screen Shot 2016-04-23 at 16.22.49

Even with the queen’s off the board, Black still is able to apply even more pressure on the position, in this case, the weakness on e4. White’s next move, 27. Ng4 is forced, but the simplifications further damage White’s position.

27.Ng4 Bxg4

Screen Shot 2016-04-23 at 16.25.05

This move was more or less forced but Black reaches the desired good knight v bad bishop endgame.

28.R1xg4 Rxg4 29.Rxg4 Rf3!

Screen Shot 2016-04-23 at 16.26.23

Very nice technique as now White must again make another concession in protecting the h-pawn. Aside from a few potential opening improvements, Matthew has looked like an expert this game. Even though he was never under any serious pressure this game, Matthew was able to demonstrate his resilience by bouncing back so nicely from a tough morning. Being able to relax in such tournament situations isn’t easy, and to pull it together in a National Championship environment is certainly admirable.

30.h4 Rf4 31.Rxf4 exf4

Screen Shot 2016-04-23 at 16.32.20

Now with a 3 v 1 set-up on the kingside, Black just needs to push his advantage to get the win.

32.h5

Screen Shot 2016-04-23 at 16.33.33

White has misplayed more than his fair share of the positions this round, but this move is the best way to put up resistance, giving the White king time to march to the kingside.

32…Kf7 33.Kd2 Kf6 34.b4 axb4 35.axb4 Nd7 36.Kd3 Ke5

Screen Shot 2016-04-23 at 16.35.06

Even in the better position, Black still slows down to make the right decision, the king belongs on e5 and not the knight. Not only can White’s king not help push c4-c5, but it must also stay in the center of the board as to prevent Black’s king from infiltrating on the dark squares.

37.Bd1 Nf6 38.Bf3 b6 39.b5

Screen Shot 2016-04-23 at 16.37.53

The last straw. Already in zugzwang, Black forces White to make one last concession. Can you figure out how Black wins this position?

39…Nd7 40.Kd2 Nc5 0-1

Screen Shot 2016-04-23 at 16.39.26

White resigned, as every legal move loses material and the game. A really strong game from Matthew. One can only wonder how much higher rated he would be if he played more often!

452_789099827892355_8572618338198414441_n
Matthew’s team, MLWGS, also fared well in Atlanta, placing 15th in the U1200 section.

Let’s check out Matthew’s round 6 match-up from the following morning and see if he kept the momentum going!

Normansell–Best (National High School Championships, 2016)
1.c4

Screen Shot 2016-04-23 at 17.23.13

Since switching away from 1 e4, Matthew’s results have become a lot more consistent with the English. As I’ve said many times with close friends, 1. c4 is the best way to start a game of chess…

1…Nf6 2.Nf3 g6 3.g3 Bg7 4.Bg2 O-O 5.O-O d6 6.d4 d5

Screen Shot 2016-04-23 at 17.26.12

And again, we reach another opening where Matthew gets to punish his opponent for wasting time in the opening. For amateur players, I find that understanding timing, development, and pawn structures is critical for improvement.

7.b3

Screen Shot 2016-04-23 at 17.28.49

Again, another no-nonsense approach from the Beast. Opting not to take on d5 to avoid Grünfeld-like positions, this move eases White towards a Catalan where Black is a tempo behind. This is a reasonable approach since the g7 bishop might be better placed on e7 in some positions.

7…c6 8.Nc3 e6 9.Qc2 Nbd7 10.Bb2

Screen Shot 2016-04-23 at 17.35.15

This move is objectively fine, but I think 10. Ba3 is also worthy of consideration, given that Black’s dark square bishop is not in a position to test the diagonal. I think after 10. Ba3 Re8 11. Rad1 White has an edge to work with.

Screen Shot 2016-04-23 at 17.40.30

White can still plan for e2-e4 ideas, but this time has full control over the dark squares. Even if Black were to try …Bg7-f8, the loss of time is apparent as Black’s remaining development is appalling.

Screen Shot 2016-04-23 at 17.43.16

10…Qc7 11.Rac1

Screen Shot 2016-04-23 at 17.44.02

Preparing for an opening of the c-file, White chooses this move . 10. e4 is interesting, but for White, it doesn’t come without cost. For example, 10. e4 dxe4 11. Nxe4 Nxe4 12. Qxe4 b6 with the future idea of c6-c5 justifies the placement of the g7 bishop.

Screen Shot 2016-04-23 at 17.57.32

11…Bh6 12.e3

Screen Shot 2016-04-23 at 17.58.24

At first, it seems kind of silly that White would have prepared e2-e4 only to make this lesser push. However, it’s completely justified! With Black’s bishop no longer on the long diagonal, White’s bishop on b2 stands uncontested. Black can’t exactly stop a future e3-e4 push, so White is in no rush to carry out this advantage.

12…Ng4?

Screen Shot 2016-04-23 at 18.00.28

Tricks are for kids! In threatening …Bh6xe3, …Ng4xe3 with a fork, Black violates nearly every opening principle. First, I’m not convinced that Black is better if he pulls off the tactic. He loses his good bishop and has to move a knight three times (three tempi is roughly one pawn) to get a rook and two pawns for objectively his best-developed pieces.  Secondly, if White defends e3, which he does, what has Black actually gain from this bizarre movement? Tactics and strategy should work together, not operate independently of one another!

13.Rfe1 Qd8 14.h3 Ngf6 15.Rcd1 Bg7 +-

Screen Shot 2016-04-23 at 18.06.17

Not only has Black lost time, he has failed to improve his position! Check this out – this was Black’s position after 10. Bb2 (Black to move):

Screen Shot 2016-04-23 at 18.07.14

Anything familiar? It’s almost like Matthew’s opponent left the board after 10. Bb2 only to find that Ra1-d1, Rf1-e1, e2-e3, and h2-h3 had all been played and it was White to move! I wondered if this realization during the game registered for Black. I think if this were to happen to me, I’d be ready to resign.

16.e4 dxe4 17.Nxe4 Nxe4 18.Qxe4 Nf6 19.Qc2

Screen Shot 2016-04-23 at 18.12.43

Seeing Matthew’s next few moves, I’m going to recommend Qd4-b1! with the idea of creating a Reti battery with Qb1-a1, losing less time shuffling pieces. Ultimately, playing on the long diagonal was the right idea, but Black is so far behind that the extra tempi almost don’t matter.

19…Qc7 20.Bc3 Bd7 21.Qb2 Qd8

Screen Shot 2016-04-23 at 18.15.13

This game is 33 moves long, and I’m going to say that eight total moves this queen takes (roughly 25% of the game’s moves!) added no constructional value to Black’s position. The queen would be poorly placed on any unoccupied square on Black’s side of the board, but of course, this is the price to pay for having wasted so much time in the opening.

22.Ne5 Qc7

Screen Shot 2016-04-23 at 18.18.40

…Five. At this point, Black’s position is beyond finding one or two good moves. From here on out we’re just going to watch Matthew’s technique.

23.d5!

Screen Shot 2016-04-23 at 18.19.49

And the long diagonal is forcefully opened. Black cannot capture the d5 pawn since Ne5xd7 wins material on either f6 or g7.

23…Be8 24.Ng4 Nh5 25.Bxg7 Nxg7 26.Nf6+ Kh8 27.d6 Qd8 28.d7

Screen Shot 2016-04-23 at 18.21.12

Black can resign here, I’ve added the end of the game for the sake of completion.

28…Qe7 29.Nxe8 f6 30.Nxg7 Kxg7 31.Qd4 e5 32.Qd6 Qxd6 33.Rxd6 1-0

Screen Shot 2016-04-23 at 18.22.05

Hard to say White went wrong anywhere in this game. I thought it was important to notice how Matthew was never in a rush to open up the position and find a win by force. Instead, he optimized his pieces and waited for the best timing to breakthrough. Well done Matthew!

16300596100_3040dbf336_o
With the way he’s been playing, I’d say he has a good chance of graduating a higher rated player than I was during my senior year!

He has one more year left in high school, but if you play competitively in the Mid Atlantic, you’ve been warned. Matthew “Beast Mode” Normansell is probably the most dangerous 1700 rated player in the state of Virginia.

More than Meets the Eye: An Attack, an Advantage, and a Blunder!

I hadn’t planned to play a rated game until Saturday’s Pittsburgh Chess League finale, but when I got the email saying my Tuesday night class had been canceled, I quickly found myself playing an extra rated game against a local expert from Carnegie Mellon University at the Pittsburgh Chess Club.

IMG_4445

Usually when I post a game to chess^summit, I make sure the selection has some sort of specific instructional purpose. That being said, I can’t say that this game can be marginalized into such a general category. Even though he fell behind early, my opponent did really well to hold and even missed a few chances to equalize!

So if today has a theme, let it be complicated positions. Honestly I can’t remember winning a game this difficult (and almost blowing it too!).

Steincamp–Li (Pittsburgh Chess Club, 2016)

1.c4 e5 2.g3 Nc6 3.Bg2 g6 4.Nc3 Bg7 5.e3 d6 6.Nge2 Be6 7.d3 Qd7
8.O-O

Screen Shot 2016-03-23 at 21.43.52
I think I’ve posted a few games with this set-up for White. Ideally, I’m going to place a knight on d5 and expand on the queenside. However, my opponent decided to change the pace of the game.

8…Bh3 9.e4 h5?!

Screen Shot 2016-03-23 at 21.45.35
Going in for the attack! Black’s intention is to open the h-file and use his h8-rook and queen to quickly checkmate my king. However, there are some downsides to this move out of principle.

1. This move doesn’t develop or get Black’s king safe.

Okay, this is obvious, but still a valid point. By postponing the fundamentals, Black risks falling behind positionally should the attack not pan out.

2. Black cannot push …f7-f5.

This is the main problem with this move. If the f-pawn is pushed, Black gives White an outpost on g5 for a knight or a bishop.

Knowing this, I opted for 10. f3, giving me the option of Rf1-f2 if needed. Furthermore, if Black tries …h5-h4, g3-g4 can now shut down the position.

10.f3 Bxg2 11.Kxg2 h4

Screen Shot 2016-03-23 at 21.52.05
Because of Black’s decision to attack, this must be played now. If 11… Nh6 12.h4, White stops all kingside play and has a simple lead in development.

12.g4

Screen Shot 2016-03-23 at 21.54.13
Not a move I was crazy about playing, but I was able to convince myself that this was right. First, Black traded off the light squared bishops, leaving the c1- and g7 bishops on the board. Black’s pawns on c7-d6-e5 are all on dark squares, making my bishop better than my opponent’s. This is important since this structure has dark-squared holes, so from e3, I can cover some of Black’s potential outposts. Furthermore, playing this move guarantees a closed h-file, limiting Black’s intentions, and leaving me with a developmental advantage.

12…h3+!?

Screen Shot 2016-03-23 at 21.59.12
My initial reaction to this move was to think that this was an error since it forces my king to safer waters and opens the g3 square for my knight. However, there are long-term benefits for Black! By controlling the g2 square, Black gets the counterplay he needs to stay alive in some lines – and according to the computer – enough to defend adequately.

13.Kh1 f5

Screen Shot 2016-03-23 at 22.03.24
I found myself perplexed by the relative speed to which my opponent was moving, but this move I felt out of principle was wrong.

As I mentioned before, the g5 square becomes weak, yet it’s not so easy to exploit. At this point, I began to look at 14. gxf5, but I didn’t like it on account of a few reasons:

Screen Shot 2016-03-23 at 22.06.15

1. The g-file opens

Even if this is tenable, I do feel like Black is getting the play he intended with his opening choice. With the g-file open, Black’s plan is to play … f5-f4 and queenside castle to bring his d8-rook over to g8. This is a lot of pressure, which brings me to my next point.

2. I’m not punishing Black!

Remember back when Black played 9… h5 when I said my opponent wasn’t following opening principles? 14. gxf5 not only fails to capitalize on this detail, it actually rewards Black for his play!

So this being said I played the anti-positional move

14.exf5?!

Screen Shot 2016-03-23 at 22.16.08

Taking away from the center! But it turns out here that matters aren’t so trivial, Black’s king is still in the center, so opening the e-file with a future f3-f4 or d3-d4 push may be lethal. It was here that I noticed that Black’s weakness wasn’t the square on g5, it was the f5 square! By taking in this manner, the structure has changed; so a pawn on g4 helps support a knight on f5 and close the g-file. As my knight reroutes to f5, my bishop will find the right moment to go into g5 and cramp Black’s position.

And the best part? 14. exf5 was one of the computer’s best moves!

14…gxf5 15.Ng3 Nd4

Screen Shot 2016-03-23 at 22.20.44
I thought this was Black’s best move, but there were several lines I had to consider before playing 14. exf5

Second Best:

15. … f4 16.Nge4 (16.Nf5?! allows 16…Nh6 ) 16. … O-O-O 17.Nd5 +=

Screen Shot 2016-03-23 at 22.22.38
The position is a little unclear here since Black can simplify, but b2-b4 is coming with a slight initiative for White.

Last Choice:

15. … fxg4 16.fxg4

Screen Shot 2016-03-23 at 22.24.24
As I’ve discussed in many of my posts, releasing the tension seldom leads to the best outcome. Here I have all the advantages I had a move ago, but the f-file is also open. It’s clear here that Black has simply run out of attacking resources.

So Black opted for the stingiest move, but it also once again neglects development and king saftey. Immediately I wanted to play 16. gxf5:

Screen Shot 2016-03-23 at 22.28.02

The concept of cousre is to break Black’s center, leaving his king out in the open. This all works if Black plays along: 16… Nxf5 17.Nxf5 Qxf5 18.f4

Screen Shot 2016-03-23 at 22.29.20

Because of the discovery threats on the queen, castling for Black comes at the cost of a pawn. However, not all captures are forcing! I soon realized that my dystopic outlook on the position was not only incorrect, but potentially losing after Black’s amazing resource, 16… Nh6!

Screen Shot 2016-03-23 at 22.32.34

This shifts the game from dynamic play to static play. With 16. gxf4? I’ve actually given up any chance of securing the f5 outpost and opened the g-file for Black’s rook. Trying to stop Black from castling with 17. Bg5 still looks grim after 17… Nhxf5 =+.

Screen Shot 2016-03-23 at 22.34.30

And here it’s clear that Black is simply better with no real counterchances for White.

So I had to be less direct, yet still keeping the position in a dynamic state. With my next move, I highlighted that the f5 pawn is still weak.

16.Nce2

Screen Shot 2016-03-23 at 22.36.39

My c3-knight was no longer planning on reaching d5 since Black can play …c7-c6 now, so trading it for Black’s best piece was appealing. Black took drastic measures with his next move, but he had several options to consider.

Scenario 1:

16… f4!

Screen Shot 2016-03-23 at 22.39.23

After some post-game analysis, I’ve come to the opinion that this was the best shot to equalize. While it creates light squared weaknesses, it neutralizes my grip on f5 and g5, while blocking in my bishop on c1. I had seen this during the game, and thought I had found a tactical resource in 17. Nxd4 fxg3 18. Re1 g2+ 19. Kg1 0-0-0 20. Nf5

Screen Shot 2016-03-23 at 22.43.40

But after some research with Stockfish, here it’s my play that’s burned out, and soon I will find that the g2 pawn is not protecting my king, it’s a protected passed pawn! All endgames favor Black here.

However, my opponent didn’t play this move when originally given the opportunity, so he must have thought the assessment was the same as before.

Scenario 2:

16… Nxe2 17.Qxe2 fxg4 18.fxg4

Screen Shot 2016-03-23 at 22.46.28

With evasive play, Black has avoided the loss of a pawn, but even after 18…0-0-0, my opponent will find his lack of development and counterplay concerning. My knight will find the f5 square, and my bishop, g5. White’s position plays itself.

Scenario 3:

16… Nh6?

Screen Shot 2016-03-23 at 22.48.35

This isn’t really a move for Black, but it does a nice job of illustrating his dilemmas after 17. Nxd4 exd4 18. Re1+

Screen Shot 2016-03-23 at 22.49.39

The win still needs work, but you get the idea. A trade on d4 eliminates Black’s ability to pressure the long dark squared diagonal, and opening the e-file will favor me.

So my opponent, uncomfortable with his options, played a move I hadn’t considered.

16. … Nxf3?!

Screen Shot 2016-03-23 at 22.51.51

The idea that opening the long diagonal will give Black strong play. However, this is the first innacuracy of the game! With this line my opponent forces me to seal in his bishop and open the e-file.

17.Rxf3 Qc6 18.Nd4!

Screen Shot 2016-03-23 at 22.53.12
The only way to refute Black’s play! In just a couple moves, Black will find himself much worse!

18…exd4 19.Nxf5 Be5 20.Bg5! +=

Screen Shot 2016-03-23 at 22.54.06
Not only is Black unable to castle, but his knight on g8 is extremely immobile. From this point on though, Black’s 12. h3+!? starts to pay off as his pressure along the light squares becomes my biggest issue.

20…Kd7

Screen Shot 2016-03-23 at 22.57.47
The only move from Black that doesn’t concede anything. While the f7 square becomes weak, my rook can’t get there due to the pin on the king. With the queen cut off from the kingside though, I decided that now would be the best time to drive the queen away by force.

21.b4 b5!

Screen Shot 2016-03-23 at 23.00.20
The best move if Black plays the continuation correctly. The idea is that regardless of what I do, Black’s queen can stay on the diagonal with the b7 (and potentially d5) square opening up. Without much to do, I made my next move, assuming my next move assuming my opponent was intending a pawn sacrifice.

22.cxb5 Qxb5?

Screen Shot 2016-03-23 at 23.02.27
A critical mistake! With this move, Black gives me an opportunity to move my queen away from the defence of the f3 rook, giving my a1-rook a chance to enter the fight. Black had much better in simply sacrificing the pawn and putting the queen in the center of the board.

Black really needed to try 22… Qd5 to force me to play slower.

Screen Shot 2016-03-23 at 23.04.33

White’s plan would be to play Qe2-e4, trade queens, and go into an endgame with small winning chances. But with my next move, my opponent realized how active I had become.

23.Qb3

Screen Shot 2016-03-23 at 23.06.50
Poking at the f7 square while giving my rook on a1 a chance to play.

23…Rf8

Screen Shot 2016-03-23 at 23.08.05
The best defense. Using the other rook doesn’t pin my knight. A sample line I looked at was 23…Rh7 24.a4 Qb7 25.Rf1, but 24. Nh4 also looked appealing, with the idea of going to g6, or bringing the rook down to f7. I hadn’t really decided since I figured the text move was far simpler for Black.

24.Rc1

Screen Shot 2016-03-23 at 23.10.56
Here I thought I was being smart, forcing the queen to go back to b7 instead of c6 to pin my rook, however, Black actually is in no rush to do this. In the game, I thought 24… Nf6 25. Ng7 was fine for White, putting pressure on e6, but 25… Nd5! was actually winning for Black. The computer says that after 24… Nf6, the position is about equal in other lines.

24…Qb7

Screen Shot 2016-03-23 at 23.13.03
So why is it so important that White convince Black to reach b7 instead of c6? Well now White has Qa4+!, and Black is forced to surrender his control of the long diagonal.

25.Qa4+ Kc8

Screen Shot 2016-03-23 at 23.14.46
Black is becoming passive, and if he had tried 25… c6, not only does he block in his queen, but I also have a turn-around tactic in 26. Nxd4! winning due to the attacked rook on f8.

26.Qc6=

Screen Shot 2016-03-23 at 23.16.32
It turns out that this simplification leads to equality since (as I soon discovered) the endgame is extremely difficult to convert.

The computer gave me an option here that holds on to my grasp on the position with 26. Rf1 Rh7 27. Kg1 getting out of the pin 27… Nf6 28. Ng3 += with a slight edge.

Screen Shot 2016-03-23 at 23.18.56

I do have to say, so far the game has been very complex, yet there have not been any missed tactics by either side. Coming from the position of strength, I have to say this is a testament to my opponent’s defensive resourcefulness to find holding moves each turn. However, with the queen trade on c6, I must win again – this time however with an advantage on the clock.

26. … Qxc6 27.Rxc6 Kd7 28.b5

Screen Shot 2016-03-23 at 23.21.46
Stopping any future a- or c- pawn advances from Black. My opponent is cramped, but with his next move, he gives up a pawn for activity, which proves to be vital for his ability to play.

28…Nh6

Screen Shot 2016-03-23 at 23.23.24
With pressure on g4, I decided I have nothing better than to win the pawn on d4. but to do this I must give up my bishop for a knight, and increase the Black bishop’s scope.

29.Bxh6 Rxh6 30.Nxd4

Screen Shot 2016-03-23 at 23.25.17

I had to make sure that this trade worked, and I think again my opponent found the best resource in 30… Rhf6. Let’s quickly look through some of Black’s choices:

30… Rxf3 31. Nxf3 Rf6 32. Nxe5+ does not win a piece! Black can prolong the fight with 32… Ke6!

Screen Shot 2016-03-23 at 23.27.38

…and White must stop the threat of mate on f1 with 33. Kg1, meaning that this is the position that must be understood. While Black may still be able to hold, I assessed that my advantage had increased since Black must give up the c7 and a7 pawns (the importance of a prophylactic measure like 28. b5!). Since I believed I had better winning chances, I was okay with this position.

Screen Shot 2016-03-23 at 23.30.38

So simplification does not come to Black’s aid. Black can’t afford to be passive either since the backward 30… Rhh8? has a tactical problem. Can you find it?

Screen Shot 2016-03-23 at 23.32.26

Here I had found 31. Rxf8 Rxf8 32. Rxc7+!! since now 32… Kxc7 is met with 33. Ne6+ with a winning minor piece endgame. Black can’t save himself with 32… Ke8, threatening mate on f1 and the knight on d4, because 33. Rc8+ forces a trade of rooks, and now I must find Nd4-f5, followed by d3-d4 to limit Black’s ability to attack my h2 pawn.

It’s clear that only White can be better, and of course I knew my opponent wouldn’t go for it. There was one last option I didn’t consider until after I had made my move in 30… Bxd4?! the concept being that my king is stuck on h1 and the constant threat of mate is a problem for me.

Screen Shot 2016-03-23 at 23.37.09

While this may be a potential drawing resource in other positions, my b5 pawn makes c7 a permanent backwards pawn and target. So in the line 31. Rxf8 Re6 32. Rc1, Black cannot both be active and defend c7 as 32… Re3 33. Rf7+ still gives White reasonable winning chances.

Screen Shot 2016-03-23 at 23.39.27

But as I said, I thought my opponent found the most aggressive try despite his time troubles.

30…Rhf6

Screen Shot 2016-03-23 at 23.40.39
My knight will return to f5 to block the f-file, after which Black can pressure the g4 pawn and emphasize my king’s awkward positioning.

31.Nf5 Rg6 32.Rc4 Rb8?

Screen Shot 2016-03-23 at 23.42.03
The second real mistake from my opponent (the first being 22… Qxb5). Time trouble played a large role in this decision, and now my not only will I eliminate Black’s annoying h3 pawn, I will get a rook on the 7th!

Black had much better in the more flexible 32… Rfg8 33.Ne3 d5 34.Ra4

Screen Shot 2016-03-23 at 23.44.20

And while Black remains a pawn down, he has reasonable drawing chances. Having a bishop in the center of the board alone should be enough compensation for the extra g-pawn, not to mention, my queenside stucture is also quite hideous.

33.Rxh3 Rxb5 34.Rh7+ Ke6 35.h3

Screen Shot 2016-03-23 at 23.45.56
Rather than immediately grab the c7 pawn, I thought it was important to nurture my two pawn advantage on the kingside. If Black tries 35… c5, I can play 36. a4, and only Black’s b5 rook is truly active.

35…Rb1+ 36.Kg2 Rb2+ 37.Kf3 Rxa2 38.Rcxc7

Screen Shot 2016-03-23 at 23.47.40
Two rooks on the 7th and my opponent in time pressure? Should be an easy win, right? Not so clear. It’s hard to secure control of the d5 square (If Kf3-e4, …d6-d5+ wins for Black), and Black does have an outside passer.

38…a5 39.Rhe7+

Screen Shot 2016-03-23 at 23.49.55
Believing I was winning since at the time I thought 39… Kd5 was unplayable (you’ll see shortly). I had calculated 39… Kf6, and now since the f6 square cannot be used by Black’s rook, my idea was Ng3-e4 creating a mating net while improving the overall position of my knight (I was fine with a bishop and knight trade since the resulting rook and pawn ending should be won).

39…Kd5 40.Rc4

Screen Shot 2016-03-23 at 23.53.02
My opponent played his move quickly, so when I dropped this and his head sunk, I thought I had won because of my mating mechanism of Nf5-e3#. Here I got up walked around to wait for the resignation but had completely had missed my opponent’s defense.

40…Rf6!

Screen Shot 2016-03-23 at 23.54.27
I give this move an exclamation for its psychological importance. With this oversight, I had now walked into a position I hadn’t analyzed and it felt like again, I had to start all over to win. However, with my opponent in time trouble, anything could happen so I made a waiting move.

41.h4 a4?

Screen Shot 2016-03-23 at 23.56.19
Black’s third mistake of the game. Advancing the a-pawn to a4 gives me a free tempo move with 42. Ra7, which is winning in all lines. Black should have also waited, but in time trouble this is hard to do, especially with my kingside pawns moving down the board.

42.Ra7 a3 43.Ra5+ Ke6

Screen Shot 2016-03-23 at 23.57.58
Finally, it’s starting to come together. Now with the king no longer on the fifth rank, I can play d3-d4, highlighting the awkward choice of squares Black’s bishop has.

44.d4 Bh2 45.d5+ Kd7 46.Ra7+ Kd8 47.Rb4

Screen Shot 2016-03-23 at 23.59.32

Missing the simplest win in 47. Ra8+ Kd7 48. Rac8, and Black must give up an exchange to stop the threat of Rc4-c7#. But at this point I was already playing my opponent’s clock – with 8 seconds left, he can never hold this, right?

47. … Rb2 48.Rxb2?? =

 

Screen Shot 2016-03-24 at 00.01.42

Here I thought that my opponent could make no progress with the b2 pawn, but with it on a dark square, his bishop can hold it until the rook comes to the rescue. So as I promised, one blunder… moral of the story? Don’t look at your opponent’s clock! If I had just spent 1 more minute, I would have realized that 48. Rxb2 allows too much play and that 48. Rba4 is a lot simpler.

48. … axb2 49.Rb7 Be5 50.Ke4 Kc8 51.Rb5

Screen Shot 2016-03-24 at 00.04.14

As my opponent correctly pointed out in our post-mortem, …Kc8-c7, followed by …Rf6-f8-b8, not only is the best mechanism but now I have to worry about losing the game entirely. White should be fine if I bring my king to c2, but my kingside pawns become weak and won’t be able to promote with the bishop on e5 guarding both g7 and h8. But I got lucky…

51…Rf7 52.Rxb2!

Screen Shot 2016-03-24 at 00.08.00
Thanks to the fork on d6, my rook is untouchable, so the endgame is now won. I can’t really blame my opponent for his mistake, but what I can say is that the mistakes will come if your opponent is in time trouble. Imagine how much less trouble I will be in if I hadn’t taken on b2!

52…Rc7 53.Rb4 Rc2 54.Ne7+ Kd7 55.Nc6 Bf6 56.g5 Rh2 57.gxf6 1-0

Screen Shot 2016-03-24 at 00.10.00

Here my opponent resigned after realizing my rook is protected on b4, and my f-pawn is soon queening. Tough game and my opponent did well to hold, but he simply just made more mistakes than me.

As I said before this (really, really long) analysis, there really isn’t a particular theme I can sum up here. But there were some key points:

  1. Early attacks mean neglecting development. Sometimes the best defense is to find ways to punish your opponent for not following the fundamentals.
  2. Captures aren’t a truly forcing move. In this game, there were two points where a pawn takes pawn move could be ignored, and thus change the entire evaluation of the position.
  3. This brings me to my next point, always evaluate who is statically better each position. This constantly changed throughout the game, so it changed the focus for each player’s goal as well.
  4. Time trouble for your opponent is not time trouble for you! Say what you want, but I’m going to kick myself for this Rxb2 move more than I’ll pat myself on the back for winning. Next time I won’t be so lucky.

I thought this was a really interesting game, and I hope you did too. For me, winning (despite some errors) was a great way to rebound from the Pittsburgh Open and start thinking about my summer calendar – specifically the US Junior Open!

Positional Domination: Hou Yifan Breaks the Ice!

It feels like a long countdown until this weekend’s G/75 Pennsylvania State Chess Championships and Pittsburgh Chess League matches, so I’ve been killing time doing opening research and watching ongoing Grandmaster games.

With Gibraltar over, there aren’t exactly many high profile games to watch, but there is the Bicontinental Match-up (South America and Antartica) between Women’s World Championship Candidate Hou Yifan and Cristobal Henriquez Villagra, an up-and-coming player from Chile.

The first round ended in a draw, where Hou Yifan was unable to convert a small advantage. For today’s post, we will be looking at the second game, one which Hou Yifan won in just 25 moves!

Hou Yifan is a player easy to overlook, but after today’s post, I think you’ll see just strong she really is. Let’s take a look:

Hou Yifan – Henriquez Villagra (Match Bicontinental de Ajedrez, 2016)

1.c4 c5 2.Nf3 Nf6 3.Nc3 e6 4.d4 cxd4 5.Nxd4 a6

Screen Shot 2016-02-08 at 20.39.02
The starting position for today’s discussion. Villagra, who eliminated Gelfand from last year’s World Cup, will set-up a hedgehog defense with the Black pieces.

6.g3 Qc7 7.Bg2

Screen Shot 2016-02-08 at 20.48.51
For those of you unfamiliar with the English, you should know that there is a lot of overlap with ideas from the Maroczy bind. One of the advantages of choosing the English move order is that the light squared bishop isn’t necessarily bad as it would be on e2 in a Maroczy Bind. Here against the Hedgehog structures, having this bishop is extremely useful, as it limits Black’s ability to queenside fianchetto, and is able to control the d5 square.

7…Be7 8.O-O O-O 9.e4

Screen Shot 2016-02-08 at 20.54.32
Here White achieves the famous bind structure with pawns on e4 and c4. Hou Yifan hopes to claim her space in the center of the board while Villagra will wait for potential weaknesses to come.

9…d6 10.Be3 Nbd7

Screen Shot 2016-02-08 at 21.03.21
A critical decision, and perhaps the beginning of Villagra’s trouble. The thematic square for the knight is c6, where it may be able to trade for the d4 knight, giving Black space and flexibility. Remember, when you are cramped, it’s advantageous to trade pieces!

11.Rc1 Ne5

Screen Shot 2016-02-08 at 20.42.30
An active looking move, but in reality, Black’s hand was somewhat forced here. Black would love to get his c8 bishop to b7, but 11…b6 would lose on the spot to 12. e5! winning the rook on a8 by discovery. Should Black try to avoid this line by playing the well-known Hedgehog idea, 11… Ra7, 12. Ndb5! is better for White after 12… axb5 13. Nxb5 Qa5 14. Nxa7 and Black will not receive two minor pieces for the rook since the knight is protected from the bishop on e3.

12.b3 Bd7

Screen Shot 2016-02-08 at 21.00.56
Black realizes that getting the bishop to b7 will simply take too much time, and chooses to route it to d7. Villagra can get this bishop to c6 and on the long diagonal, but as you may notice, Black is somewhat cramped.

13.h3

Screen Shot 2016-02-08 at 20.42.47
Taking away the g4 square from each of Black’s knights before pushing f2-f4. While Hou Yifan has easy moves, improving her structure, it is already not so clear how Villagra is going to reroute his pieces to organize an attack. The Chilean’s next move is really telling as to Black’s struggles in this position.

13…Qa5

Screen Shot 2016-02-08 at 21.08.21
Rather than improving the position, Black must spend a tempo to evade a tactic – that’s right!
Screen Shot 2016-02-08 at 21.10.38
So if Black makes the most positionally improving move, White can force Black into a well known Hedgehog dilemma with 14. f4 Nc6 15. Nxc6 Bxc6 16. Nd5!
Screen Shot 2016-02-08 at 21.12.19
I actually made this observation before checking with an engine, and the computers seem to see the moves merit. Black’s problems on the b6 square make recapturing the knight compulsory, after which, Black must not only give up the bishop pair but have a strategically ruined endgame.
Screen Shot 2016-02-08 at 21.16.09
Black’s isolated pawn on d6 blocks in his dark squared bishop, and White’s pure control of space is enough for White to push for a win. Seeing this (or other similar lines), VIllagra chose 13… Qa5.

14.Qd2 Rfc8 15.f4 Nc6 16.Qf2 Bd8 17.Rfd1

Screen Shot 2016-02-08 at 20.43.08
Black’s moved the c6 knight three times, the queen twice, and the d8 bishop twice. Meanwhile, White has optimized all of her pieces, acquiring a major space advantage. Only a pair of pawns have been traded, and because of it, Black is cramped and has little oxygen.

17…Ne8?

Screen Shot 2016-02-08 at 21.22.06
Here Black really needed to trade on d4, but was afraid of 17… Nxd4 18. Bxd4 following with e4-e5, opening up the position. The Chilean wanted to be able to keep the position somewhat closed with d6-d5, but Black is beyond the point of having choices.

18.Nf3! Nb8

Screen Shot 2016-02-08 at 20.43.19
Black’s backwards play these last few moves have been strictly tied to playing …d6-d5. This move puts some pressure on the c-file, but Black’s lack of development makes the threat anything but lethal. One principle to know here is that if you are better developed than your opponent, it’s in your best interest to open up the position. Here the former Women’s World Champion pushes through with a central break.

19.e5 d5

Screen Shot 2016-02-08 at 20.43.31
And Black finally gets his break! But it’s this same move that actually ends the game for Black.

20.Nd2 Qb4 21.a3 Qxa3

Screen Shot 2016-02-08 at 21.28.25
Dragging the queen offsides while solidifying the queenside. Without the queen on a5, Black will even fewer ways to defend the collapsing center.

22.cxd5 exd5 23.Ra1!

Screen Shot 2016-02-08 at 20.43.48
And now Black’s queen must retreat all the way to f8 to avoid the wrath of the c3 knight. With the exception of the light-squared bishop, Black has placed all of his pieces on the back rank.

23…Qf8 24.Nxd5 Be6 25.Nc4 1-0

Screen Shot 2016-02-08 at 20.43.59

Black threw in the towel here, as there’s no easy way to defend against f4-f5 and Nb6 threats. Complete positional domination from the Chinese Grandmaster as she dispatched her opponent while making it look easy! There are two games left in the match, and it’ll be one of the last opportunities to watch Hou Yifan before the Women’s World Championship in March when she takes on the reigning champion, Mariya Muzychuk.

Opening Experiments on ICC

For those of you who may recall, I did a video + analysis post on the Berlin last month, and today I decided to try a similar format for a new opening. I played 1 d4, hoping for a Queen’s Gambit or Nimzo-Indian, but my opponent instead tried a Dutch. In an effort to be different, and have something new to talk about Tuesday, I tried 2. Nc3 to immediately threaten e2-e4.

After going into a “Leningrad Structure”, I tried a thematic h2-h4-h5 push to bust open my opponent’s king for what should have been a routine win. However, being careless in my calculations, I missed a simple way to extract my opponent’s king and had to find a cool mating idea later to get the result. See if you can find the win before I did!

Since my opponent didn’t exactly play winning chess, I think on Tuesday, my goal is to answer 2 questions:

1) Why is 2 c4 more common than 2 Nc3 against the Dutch?

2) How is Black supposed to stop the h-pawn push in the Leningrad Dutch – and can White make it even more effective?

That being said, I hope you enjoy today’s video!
