Opening Exploration: Navigating the Najdorf

To follow up on last Tuesday’s video, I put together an analysis on the Be3 Najdorf, with improvements for Black. For those of you that missed the video, make sure to check out White’s refutation of my set-up:

For those of you who saw it, here are some of the highlights:

DarwinEvolution–leika (G/15 Internet Chess Club)

1. e4 c5 2. Nf3 d6 3. d4 cxd4 4. Nxd4 a6 5. Nc3 Nf6 6. Be3 e5 7. Nb3 Be7 8. f3

Screen Shot 2016-02-25 at 22.29.23
This will be the tabiya position for today’s post. In the game, I veered off with 8… Nbd7, but today I will suggest the main line, 8… Be6.

8…Nbd7 9. Qd2 Qc7 10. g4 h6 11. O-O-O b5 12. Kb1 Bb7 13. a3 Rd8 14. Qf2!

Screen Shot 2016-02-25 at 22.37.06
And now Black is paralyzed! No longer able to play …Nb6 to push …d7-d5, I no longer have an active plan, and must wait for White to take action.

I could have tried to insert …Nb6 earlier, with the idea of reaching c4, but even in those lines, my light squared bishop is slightly misplaced. Why did I go for this set-up? Let’s take a field trip back to the third video I ever posted to chess^summit, back in October 2014:

In that game, the set-up was justified in that game because White not only wasted several tempi but also with a bishop on e2, the Qf2 idea was never possible. That game was actually one of the last times I employed the Najdorf, so I never really worried about going beyond the analysis I had at that time.

Screen Shot 2016-02-25 at 22.29.23

So that brings us back to the tabiya position. As I mentioned before, Black’s bishop is slightly misplaced on b7, so here 8…Be6 is the much more logical step going forward. Note how I can still play for …d7-d5 if the opportunity presents itself, but I also get more space on the queenside, while eying the b3 knight for a potential trade. With the bishop on b7, White can play a2-a3 to stop the b-pawn push without worrying about opening the c-file.

Our first game is from the 2013 Tal Memorial, featuring Boris Gelfand with Black against Fabiano Caruana.

One thing you should note about this opening is that unlike my other analysis posts, the calculation must be much more concrete. The Najdorf is not for the faint-hearted, and will punish the tactically weak!

Caruana–Gelfand (Tal Memorial, 2013)

1. e4 c5 2. Nf3 d6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 a6 6. f3 e5 7. Nb3 Be6 8. Be3 Be7 9. Qd2 O-O

Screen Shot 2016-02-25 at 23.44.56
Thanks to modern computer analysis, castling is the most popular option for Black. While the play is sharp, Black’s king is actually safe with best play.

10. O-O-O Nbd7 11. g4 b5 12. g5 b4!

Screen Shot 2016-02-25 at 23.47.09
The key to handling a race position is to not be afraid to be persistent! Black doesn’t have time to waste and immediately attacks White’s knight, leaving his own under attack.

13. Ne2 Ne8 14. f4 a5 15. f5 a4!

Screen Shot 2016-02-25 at 23.49.03
Same idea again! While White’s attack is scary, Black has also gained a lot of momentum. It’s important to not reward White for simply going first.

16. fxe6 axb3 17. cxb3 fxe6

Screen Shot 2016-02-25 at 23.52.01
What just happened? Black opened the a-, c-, and f-files for his rooks while simultaneously liquidating White’s pawn storm. Black’s queenside pawns were also traded down, but offer Gelfand a lot of tactical opportunities.

18. Bh3 Rxa2 19. Bxe6+ Kh8

Screen Shot 2016-02-25 at 23.54.11
White also gained from the earlier trading. For White to make progress, he must take advantage of Black’s lack of a light squared bishop.

20. Ng3 Nc7 21. Bc4 Qa8

Screen Shot 2016-02-26 at 01.11.33
The computer assesses this position as equal, but one of the great things about the Najdorf is that the positions are very rich, as each side take turns attacking the other.

22. Rhf1 Rxf1 23. Rxf1 Ra1+ 24. Kc2 Rxf1 25. Bxf1 d5!

Screen Shot 2016-02-26 at 01.13.31
Black justifies giving up the bishop pair by making the thematic …d6-d5 push, eliminating his main structural weakness.

26. h4 d4 27. Bg1 Ne6 28. Qe2?

Screen Shot 2016-02-26 at 01.15.29
Who would have thought that this would be the critical mistake? A seemingly innocuous choice from Caruana but this move gives Black a key tempo. By not maintaining pressure on the b4 pawn, Black gets time to put a knight on c5, as well as threaten …d4-d3.

28…Ndc5 29. Qc4 Nf4!!

Screen Shot 2016-02-26 at 01.20.48
Black’s knight’s are both active while Caruana’s bishops have yet to join the fray. What’s wrong with 30. Qxb4? Gelfand must have seen 30…Bf8! protecting the bishop while threatening a discovery. Black is winning in that line after 31. Qc4 Qa2 -+ as Black can’t easily stop the c5 knight from coming into d3.

30. Qf7 Qf8 31. Qc4 g6 32. Bf2 Ne2!!

Screen Shot 2016-02-26 at 01.25.21
Another punishing blow from Gelfand! If White takes the knight, he must be prepared for the black queen to enter the 2nd rank by taking the bishop on f2. Caruana chose the only move to try and hold the fort.

33. Nh1 d3+ 34. Kd1 Qf3

Screen Shot 2016-02-26 at 01.26.58
Now busting through the kingside, Gelfand has managed to win on both sides of the board. At this point, it’s just technical.

35. Bxc5 Qxf1+ 36. Kd2 Nf4!

Screen Shot 2016-02-26 at 01.28.10
A quiet move – Black plans to put the queen on e2 and follow through with checkmate, so White doesn’t have time to grab the bishop.

37. Ng3 Qg2+ 38. Kc1

Screen Shot 2016-02-26 at 01.29.41
38. Bxe7 would have lost on account of 38… Qe8#

38…Qxg3 39. Kb1 Ne2 40. Qf7 Qe1+ 41. Ka2 Nc3+ 0-1

Screen Shot 2016-02-26 at 01.31.09
Caruana resigned. There’s simply no way for White to make use of his active pieces, as a sample line would go 42. bxc3 Qd2+ 43. Kb1 Qc2+ 44. Ka1 Qxc3+ 45. Ka2 Qxc5, and the d-pawn will promote with no three-fold chances for White.

What does this game tell us about the Be3 lines of the Najdorf? Well, it’s extremely tactical, and Black can’t play submissively if he has any aspirations of winning. Another aspect I will mention is that to play the Najdorf takes a lot of preparation – for each side; working with computers, reading manuscripts, analysis far deeper than the post I have provided you with today.

I stopped playing the Najdorf shortly after breaking 1900, because I found that it simply put too much emphasis on opening knowledge when playing 2000+ rated opponents, and the Bg5 lines alone gave me enough of a headache to stop. If you’re looking for a fun, easy opening to learn, this definitely isn’t it.

How to Not Win a State Championship!

For those of you who may know me well, one tournament that has always been just out of my reach is the Virginia Scholastic State Championships. Since the third grade, I’ve always been competitive in my section, with five top ten finishes to show for it. Though my scholastic days have been over for a long time, I’m still chasing at least one state championship title.

DSCN1187
After some rough years in middle school, I managed to claim two 8th place finishes in both my 10th and 11th-grade years. My senior year wouldn’t prove so easy, and thus the curse of not winning states continued.

This past weekend, I had my first real opportunity to become a state champion, as I was seated at board 1 going into the final round of the G/75 Pennsylvania State Chess Championships against defending champion Mark Eidemiller. I had scored 2.5/3, with two somewhat quiet wins, and a draw against a 2200 rated opponent. I shared my first round win last Tuesday:

My opponent had won each of his three games in a convincing manner, so I had to win to get the championship honors. Let’s see how it went:

Steincamp–Eidemiller (G/75 Pennsylvania State Championships, 2016)

1.c4 e6 2.g3 Nf6 3.Bg2 d5 4.Nf3 Be7 5.O-O O-O 6.b3 b6

Screen Shot 2016-02-18 at 15.21.28
An interesting choice by my opponent, I thought he would opt for the much more active and popular 6…c5. While my opponent’s choice to change the move order added its own wrinkle to the game, I think he would choose a different line if we were to replay this game.

7.Bb2 Bb7 8.d4 c5

Screen Shot 2016-02-18 at 15.24.34
I’m guessing the point of Black’s move order switch. In an effort to deviate from main line Catalan positions, Eidemiller happily takes the hanging pawns structure.

9.cxd5 exd5 10.dxc5 bxc5 11.Nc3

Screen Shot 2016-02-18 at 15.26.42
One of the problems of playing with the hanging pawns is that now I have a lot of dynamic potential. This knight can reroute to a4 to put pressure on c5, opening up the half-open file for my rook to go to c1. Black is still somewhat undeveloped, and should he choose to move his c- or d-pawns forward, he will create weak squares for my pieces to land.

11…Re8 12.e3 Na6 13.Rc1 Nc7 14.Na4

Screen Shot 2016-02-18 at 15.29.37
In this position, I already have a slight advantage, as Black hasn’t solved the problems with his pawn structure. Meanwhile, his knight on c7 is somewhat misplaced.

14…Ne4 15.Nd2 Ne6 16.Nxe4 dxe4 17.Qc2!

Screen Shot 2016-02-18 at 15.31.01
The move my opponent must have missed! Even if Black can hold onto his pawns, he will stay chained to his weaknesses on c5 and e4 while my pieces spring to life. Already, I was very optimistic about my chances of winning.

17…Bf6 18.Bxf6 Qxf6 19.Nxc5

Screen Shot 2016-02-18 at 15.32.59
As Dorfman would say – a static advantage handled correctly will always become a material advantage. Now up a pawn, I just need to limit Black’s play and this game is mine, right?

19…Rac8 20.Nxe4!

Screen Shot 2016-02-18 at 15.34.14
Two pawns are better than one, right? Here Black can’t touch my queen since I have the intermezzo capture on f6 with a check and I will end up an exchange.

20…Qe5 21.Qb1!

Screen Shot 2016-02-18 at 15.35.42
The queen is surprisingly well placed here! If Black isn’t careful and plays 21… f5?! 22. Nf6+ is strong since I can take the bishop on b7 while my queen points at the weak f5 pawn. So far I’m playing really well, absolutely crushing my 2300+ rated opponent.

21…Ba6 22.Rxc8 Rxc8 23.Rd1 f5 24.Nd6 Rd8 25.Rd5

Screen Shot 2016-02-18 at 15.38.03
This is the only move that justifies my choice to play Ne4-d6 earlier. Now the f5 pawn is won with proper calculation!

25…Qc3 26.Nxf5 Bd3

Screen Shot 2016-02-18 at 15.37.40
The critical position of the game. This is Black’s last chance to bring this game back to life, as the endgame is no longer tenable. However, the game having gone so smoothly for me, I was shocked to see that I had missed this line in my calculation and blundered. Here is my first regret – not relaxing and playing 27. Rxd8+ Nxd8 28. Qd1! and the pin on the bishop saves my knight on f5. Instead, I made a much less pragmatic decision.

27.Qxd3??

Screen Shot 2016-02-18 at 15.41.48
This move actually works tactically, but because I didn’t see the idea when I took here, I give it the two question marks. I was actually so nervous/excited/scared, that I took the bishop, thinking I was just winning a piece! Unfortunately, chess isn’t so easy.

27…Qxd3 28.Rxd3 Rxd3

Screen Shot 2016-02-18 at 15.43.31
My last chance to win the game, can you find it? White to move.

29.Be4

Screen Shot 2016-02-18 at 15.44.13
This move certainly wasn’t it, but if I had only pushed the bishop one square further and played 29.Bd5! I would have won the game. 29… Rxd5 loses on account to Ne7+, and 29… Kf7 enters a lost ending after 30. Nd4.

Unfortunately, with this misstep, the computer evaluation dropped from +5.3 to +0.3, which was more than enough for my opponent to hold the draw. So what did we learn from this game?

The game isn’t over till the players shake hands.

I would be State Champion if I had taken 26…Bd3 more seriously and calculated out the whole line or just found the trade on d8. I’m perfectly capable of calculating both lines, but in that precise moment I was too excited to think straight, which leads me to my next point.

Don’t play quickly.

I had a couple regrets this game, and ultimately, there is no going back. Even if I was excited, a trip to the water fountain or a walk around the tournament hall could alone have saved the game and been the difference.

Relax.

There was no need for me to get excited because I hadn’t done anything yet! Even though the opening went well in my favor, that alone didn’t win the game. I just had to be patient.

I’m sure I’ll break the curse one day in the near future, but I am at least happy I finally made it to the top board heading into the final round of the tournament – already the farthest I’ve made it thus far.

Pushing for the Initiative

This past weekend proved to be a back-and-forwards kind of performance, as I came really close to winning my first state championship, only to lose it at the final moments of my last round. I wanted to share that game in more depth, but with midterms this week, I’ve decided to analyze them later this week.

Meanwhile, check out this quick video on my first round win! Even though I was up a pawn, converting the advantage wasn’t so easy. Check it out to see how I did it!

Zurich Chess Challenge 2016: Opening Thoughts, Predictions

It’s been about two weeks since my last rated game, so to make up for the void, I’ve been watching a lot more Grandmaster games live to mix up my preparation. Last Tuesday, I posted Hou Yifan’s dominating win over Cristobal Henriquez Villagra, where she used a massive space advantage to crush a hedgehog gone wrong.

With the Zurich Chess Challenge starting today, I thought I’d break down some of the major headlines going into the tournament for players unsure of what to look for.

Screen Shot 2016-02-11 at 16.18.44
This year’s edition of the Zurich Chess Challenge offers top level entertainment from Vladimir Kramnik, Hikaru Nakamura, Vishy Anand, Alexei Shirov, Levon Aronian, and Anish Giri.

Who Strikes First?

With the Candidates tournament in March, expect Nakamura, Anand, Aronian, and Giri to keep their new ideas close to their chests. What does this mean? Kramnik and Shirov will likely be the providers of any new opening plot twists, and perhaps take more liberties with their choices from the start. Kramnik isn’t known to rely on aggressive opening innovations (rather more positional, solid play), but Shirov, author of Fire on Board, may entertain us with a splurge of aggressive opening selections. If Shirov pulls off an upset, don’t be surprised.

What does age mean?

This is the big question, especially for former World Champion Vishy Anand. Last year, he played in a tie-breaker match for this very tournament. This year? It might be a miracle he makes it that far with his recent form. While most of the chess world has been busy criticizing Magnus, Anand’s been slipping since last summer’s Sinquefield Cup, with a disastrous performance in both London and Gibraltar. The tumble has seen India’s number one fall out of the top ten, and nearly eclipsed by Pentala Harikrishna.

For Anand, doing well in Zurich means changing the trend before going into the Candidates tournament. If Vishy can’t leave the Chess Challenge with at least a 50% score, don’t expect him to last long in the Candidates either – it’s a long road back to getting to the top.

Solid is strong, but can it win?

This one’s for Giri. The fourth best player in the world is going to have to win games in order to come out on top in Zurich. Anish left Tata Steel with a 7/13 score (2 wins, 1 loss, 10 draws), but with lucky breaks against Hou Yifan and Fabiano Caruana, it could have been worse. This tournament features two opponents Giri has never beaten – Kramnik and Aronian.

Anish is one of the most consistent players in this field right now, so even if he fails to emerge victorious, he will still be in good shape for the Candidates.

Does Aronian’s style trump that of Nakamura?

Realistically, the Aronian v. Nakamura match could decide the winner of the tournament. Levon’s 2015 got off to a rocky start, but he’s been playing at his best form since his Sinquefield Cup win. Nakamura, the “2015 player of the year”, will seek to improve from his 1st place finish at Gibraltar. Aronian has nine wins over Nakamura in classical play, compared to Hikaru’s two.

I expect this game to also be a critical moment in the Candidates tournament in Moscow as well, so depending on how this game plays out, it could be a great indicator as to who will do better in March.

How strong is the world #2, really?

His rise to second best has been a quiet one, as he hasn’t had too many recent games at the top level events. That being said, Vladimir Kramnik has always been among the world’s elite, and his latest appearances in Qatar and the European Club Cup should show that. At 4o, a lot of chess fans write off the Russian, but I think this is a promising opportunity for Kramnik to show he isn’t done.

How does it finish?

This is a fairly balanced field, and any exceptional performances will definitely form big impressions for the rest of 2016. That being said, here’s how I see Zurich finishing out:

1. Levon Aronian

2. Hikaru Nakamura

T3. Vladimir Kramnik

T3. Anish Giri

5. Alexei Shirov

6. Viswanathan Anand

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.

Navigating the Maze: Games of Gibraltar

I’ve spent the last few days watching the Gibraltar Open, and now that it’s come to a close, I wanted to share some of the more interesting and instructive moments of the tournament.

Sebastien Maze, of France, proved to be one of the Cinderella stories of the tournament with a score of 7/10. We first look at his game against Ni Hua.

The first game I wanted to show was from round 9, Ni Hua–Maze, where a massive space advantage against a Berlin failed to materialize and then came crashing down to allow the Frenchman to convert the won endgame. If you’re unfamiliar with the Berlin, I highly recommend you check out my comprehensive post on the opening here.

Ni Hua – Maze (Tradewise Gibraltar, 2016)

1.e4 e5 2.Nf3 Nc6 3.Bb5 Nf6 4.O-O Nxe4 5.d4 Nd6 6.Bxc6 dxc6 7.dxe5 Nf5 8.Qxd8+ Kxd8 9.h3 Ke8 10.Nc3 Be6 11.g4

Screen Shot 2016-02-04 at 13.30.55
A more aggressive try than both the Vachier-Lagrave–Giri and Karjakin–Radjabov games we analyzed earlier. Here White gains space with tempo, punishing the knight on f5 for its awkward placement before Maze has the opportunity to insert the thematic …h7-h5.

11…Ne7 12.Nd4 Bd7 13.f4

Screen Shot 2016-02-04 at 13.33.54
Wasting no time gaining space on the kingside. Needing a win, Ni Hua takes the risk of hyper-extending, with the hopes of just cramping Black while optimizing his pieces.

13…h5!

Screen Shot 2016-02-04 at 13.35.28
Statically worse, Maze takes dynamic measures to change the nature of this position. With the goal of opening the h-file, the Frenchman hopes to activate his kingside rook to attack White’s pawns. Should White blunder here with 15. g5? the f5 square becomes a permanent outpost for Black, so Ni Hua must concede the trade.

14.f5 hxg4 15.hxg4 Rh4 16.Rf4

Here is the critical position. Visually, White looks much better, sitting pretty with his space advantage. Meanwhile, Maze has to solve his issues of development while fending off any of White’s tactical opportunities, such has e5-e6 ideas. Clearly Black’s opening has failed, right? Think again. As I mentioned before, Black is only statically worse. If he can find dynamic opportunities, Maze can liquidate White’s kingside pawn mass and reach a better endgame. Already, Black can consider both …g7-g6 and …g7-g5, trying to create a square for his knight on g6. With White’s light squared bishop gone, moving the f-pawn would be a major concession. If Maze can make this pawn move then he’s moving in the right direction.

16…Rd8 17.Be3 Bc8 18.Re4 g6! 19.Rf1

Screen Shot 2016-02-04 at 13.46.16
Already, Ni Hua is finding that it’s not so easy to convert his space advantage. Even with all of his pieces on great squares, its not so easy to see what the next course of action is.

19…Rh3!

Screen Shot 2016-02-04 at 13.49.04
With the pawn on g4 adequately protected, Black offers White tactical problems. Threatening to take two minor pieces for a rook, Ni Hua realized that he was in trouble and went all in with 20. e6 on the next move. But to illustrate some of the problems, let’s check out some lines.
Screen Shot 2016-02-04 at 13.53.27
The most aggressive move also presents problems for White. After 20. Bg5, Black can play 20… gxf5 and should White err with 21. gxf5?? Rg3+ will win immediately for Black. To recapture on f5, White would have to play 21. Bxe7, but giving up the bishop pair in an endgame bound position is not ideal.
Screen Shot 2016-02-04 at 13.57.19
Should White decide to get his bishop out of the way, for instance, 20. Bc1, Black can sacrifice an exchange to get an attack on the king with 20… gxf5 21. gxf5 Rxd4 22. Rxd4 Nxf5 23. Rdf4 Bc5+ and Black will have to give up an exchange to stay in the game.

20.e6?!

Screen Shot 2016-02-04 at 14.01.50
An interesting try to avoid the lines mentioned above, but unfortunately for Ni Hua, Maze’s earlier move 18… g6 was already enough to liquidate to an endgame slightly better for Black.

20…Rxe3!

Screen Shot 2016-02-04 at 14.04.01
Following through on his threat, and with the next few moves forced, Black will end the line up a pawn.

21.exf7+ Kxf7 22.Rxe3 Rxd4 23.fxg6+ Kg8

Screen Shot 2016-02-04 at 14.06.30
It seems like Ni Hua can force the coronation of one of his pawns, but it’s Maze that sees a move further. One of the reasons why I like this game is that its hard to see where White went wrong, yet after 19… Rh3, it became clear that something wasn’t quite right for White. I’m no expert on the Berlin, but I would say that White’s hyper-extension instead of more principled play was enough to derail this game from equality.

24.Rxf8+ Kxf8 25.g7+ Kf7 26.Rxe7+

Screen Shot 2016-02-04 at 14.09.40
Ni Hua will get his wish, but…

26…Kxe7 27.g8=Q Rxg4+

Screen Shot 2016-02-04 at 14.10.23
… Maze achieves his goal, a bishop v knight endgame, and a pawn up! Maze went on to convert the endgame, reaching a 7/9 mark to be tied for first going into the last round.

In this next endgame, we saw a draw cost both sides an opportunity to make the playoffs with Hikaru Nakamura and Maxime Vachier–Lagrave. In the end, it was Pentala Harikrishna that was unable to convert his position of strength to a birth in the play-off.

Despite missing out on an opportunity to play for frist, Harikrishna’s performance leaves him less than 6 rating points lower than the best player from India, Vishy Anand.

Harikrishna – Li Chao (Tradewise Gibraltar, 2016)

Screen Shot 2016-02-04 at 14.19.12
Here Li Chao offered Harikrishna a queen swap on c6, believing that the resulting rook and opposite colored bishop endgame was a draw. Though it may be tenable, White still has enough resources to play for the initiative. Both of Black’s pieces are limited in mobility defending the e7- pawn and White’s king can march to the action undisturbed.

45.Qxc6 bxc6 46.f4!

Screen Shot 2016-02-04 at 14.22.50
Good technical play! Harikrishna intends to push the f-pawn to f5 limiting the f7-bishop and then plans to bring in the king. Unfortunately, Li Chao can’t do much more than sit around, as playing …f6-f5 himself will create an unbreakable box for his bishop. Black is paralyzed.

46…Kh7 47.f5 g6 48.Kf2

Screen Shot 2016-02-04 at 14.25.05
Without concern for the f5-pawn! If White had taken on g6, he gives Black an easy route to the center of the board via g6-f5-e6 with good drawing chances. However, a Black pawn on f5 would constrain Black as White advances his king.

48…gxf5 49.Ke3 Kg7 50.Kf4 Bg6

Screen Shot 2016-02-04 at 14.27.27
I think this position really illustrates Black’s dilemma as space becomes a big concern here. It’s up to White now to find the win.

51.Rd4 Rg8 52.Rd6

Screen Shot 2016-02-04 at 14.28.52
I started to lose sight of what Harikrishna’s idea was since his last move seemed intended to capture on a4. After looking at this position with an engine, my computer showed that with accurate play, Black can hold a fortress as the advantage is only visual. That being said, Harikrishna really needed to make a second weakness here, and pushing the b-pawn up the board seems to me the best chance, regardless of the outcome. If you think White has a simple win here, I encourage you to play this position against an engine! Black’s ready to turn off the lights with …Bg6-e8, and it’s not clear if there’s enough power for white to generate a win.

52…Be8 53.Kxf5 Bg6+ 54.Ke6 Bf7+ 55.Kd7 Be8+ 56.Kd8

Screen Shot 2016-02-04 at 14.36.33
Harikrishna’s gotten his king to the back rank, but with no light square control, the e-pawn will never promote.

56…Kf7 57.Bc5 Rxg2 58.Bd4 Rg6 59.Bc3 c5 60.Rd5 Rg8 61.Rxh5 Bb5+

Screen Shot 2016-02-04 at 14.35.04
And with White having to surrender his e7 pawn, the final position is drawn. The players made a couple more moves and shook hands when it was clear neither side would falter.

62.Kc7 Kxe7 63.Rf5 Be8 64.Rxf6 a3 65.Ra6 axb2 66.Bxb2 Rg6 67.Rxg6 1/2-1/2

I missed the Nakamura–MVL match-up for first prize, but after four draws, Nakamura won the armageddon game with the Black pieces to win Gibraltar for the second consecutive year. This year featured a strong section, and the tournament becomes more interesting with each year as the organizers find new players to invite – I’ll be curious to see who plays next year!

This Saturday, I will be playing Grandmaster Alexander Shabalov in a simultaneous exhibition at the Pittsburgh Chess Club – so make sure to look out for the “Grandmaster Eats Me Alive” video that will come out Sunday, I’m looking forward to seeing how the reigning US Open Champion will plow through my repertoire!

Five for Five: Winning with the Bishop Pair

This past Sunday marked a landmark win for me, as I managed to continue my perfect record in the Pittsburgh Chess League, getting my fifth win in five games. Getting a result not only meant helping my team, the Univesity of Pittsburgh, beat Carnegie Mellon University 3-1, but also meant extending my unbeaten streak in four-board team events to eleven games (8 wins, 3 draws).

I thought that this game was rather instructive, as the result was a direct reflection of the positional imbalances that occurred during the game, a pair of bishops against the pair of knights. Let’s have a look:

Steincamp – Puranik (Pittsburgh Chess League, 2016)

1.c4 Nf6 2.g3 c6 3.Nf3 d5 4.Bg2 Bg4

Screen Shot 2016-02-01 at 09.50.14
One of the advantages of playing …c7-c6 before …e7-e6 is that Black has the option of developing his light squared bishop to a more active square.

5.O-O Bxf3?

Screen Shot 2016-02-01 at 09.52.34
It’s only move 5, but Black has already made a critical mistake! With this move, Black gives away the bishop pair for no compensation. While Black’s pawn chain from b7-d5 seems to blunt my bishop, attacking b7 will eventually force Black to concede the diagonal.

6.Bxf3 e5

Screen Shot 2016-02-01 at 09.55.29
Black grabs the center here with this move, with the hopes that a space advantage will outweigh the bishop pair. However, I have a nice resource – can you find it?

7.d4!

Screen Shot 2016-02-01 at 09.57.16
It was critical that I play this move first. 7. d3 is too passive, and 7. Qb3 is easily met by 7… Qb6. This move forces a transposition to one of two common openings:
Screen Shot 2016-02-01 at 09.59.29
Should Black choose to capture on d4, we have a reversed Main Line Alapin where White has the Bishop pair and an advantage in any endgames. For example 7… exd4 8. Qxd4 dxc4 9. Qxd8+ Kxd8 10. Bg5 Nbd7 11. Rc1 and my activity will offer me fair winning chances.

7…e4

Screen Shot 2016-02-01 at 10.02.02
My expert opponent chose this move, which transposes into a Main Line Reversed French, with a few critical distinctions. 1) My pawn is on e2, not e3, so I don’t have the familiar “bad French bishop”, 2) without his light squared bishop, my opponent will find it difficult to defend both b7 and d5, and 3) already behind in tempi, Black has still yet to castle, which makes f2-f3 powerful if timed correctly.

8.Bg2 Nbd7 9.Nc3 Bb4

Screen Shot 2016-02-01 at 10.06.17
In an effort to stop f2-f3 with …Bxc3, Black offers his second bishop. While this solves a short term problem, Black surrenders a lot of attacking potential without his dark square control.

10.Qb3

Screen Shot 2016-02-01 at 10.05.42
This move forces Black to give away his bishop, and when he does, I will recapture with the b-pawn for two reasons. 1) To allow my bishop to develop via a3, and 2) to make a half open file targeting Black’s weakness. If the b7 pawn moves or falls, Black’s position will crumble.

10…Bxc3 11.bxc3 Qb6 12.Ba3!

Screen Shot 2016-02-01 at 10.10.10
This move stops Black from castling kingside. It was important to not trade queens on b6, as Black could recapture with the knight and then head to c4 with some counterplay.

12…dxc4?

Screen Shot 2016-02-01 at 10.11.44
This move not only opens the position but drastically weakens Black’s e4 pawn. By opening the diagonal for my queen, the f7 pawn can also become a weakness in some lines. Black had to try 12… Qxb3 13. axb3 dxc4 14. bxc4 Nb6 but Black still has the long term disadvantage. During the game, I found 15. Bc5 to win the a-pawn, but my friend found 15. Rfb1 which is stronger, cleaning Black’s queenside majority.

13.Qxc4 Qa5 14.Qb3 b6 +-

Screen Shot 2016-02-01 at 10.15.03
In my mind, this move gave me the win. This not only weakens the diagonal but also means Black’s king won’t be safe on the queenside. Knowing this, I deemed it appropriate to go on an all-out assault on the monarch.

15.f3!

Screen Shot 2016-02-01 at 10.16.48
A thematic move in the French, and the winning move here. I calculated a bunch of winning lines here tactically, but I could have also just relied on pure intuition, for example:
Screen Shot 2016-02-01 at 10.18.21
15… Nd5 is not Black’s best move, but it highlights the issues with his position the most after 16. fxe4 Ne3 17. Qxf7+ with mate soon to follow.
Screen Shot 2016-02-01 at 10.19.57
This move only postpones Black’s problems as 16. c4 will pick up the pawn as 16… Qd2 fails to 17. Rad1 Qxe2 18. Rde1 Qd2 19. Rxe3+ Kd8 and Black is clearly much worse.
Screen Shot 2016-02-01 at 10.22.14
15… exf3 with the idea that if 16. exf3 0-0-0 is a bold one, although it offers Black some chances to get play on the e-file. That’s why I had prepared 16. Bxf3 so 16… 0-0-0 fails to 17. Bxc6, and I still have a massive pawn center after e2-e4.

15…O-O-O

Screen Shot 2016-02-01 at 10.26.15
Black just decided to give up the pawn for the sake of king safety, but my bishop’s view from g2 is quite nice.

16.fxe4 Qh5 17.Qc4

Screen Shot 2016-02-01 at 10.27.24
Both attacking and defending! Black had two threats, …Nf6-g4 and …Qh5xe2. This move defends the e2 pawn, and any of Black’s mating threats are secondary to Qc4xc6+ with Ba3-d6# to follow.

17…Kb7 18.e5

Screen Shot 2016-02-01 at 10.29.21
Highlighting the inevitable problem Black would face when he chose …e5-e4. At some point this diagonal would open, and without any light square protection, Black is doomed. My opponent sacrificed a piece, but that failed to parry my plans.

18…Nxe5 19.dxe5 Nd5 20.Bxd5 Rxd5 21.Bd6

Screen Shot 2016-02-01 at 10.31.00
Cutting off the rook with two ideas, e2-e4 to expose f7 or Ra1-d1, simply to trade the rooks and go into a won ending.

21…Re8 22.e4 1-0

Screen Shot 2016-02-01 at 10.32.23
Black resigned, seeing that 22… b5 23. Rab1 will force Black to give up the rook or conceded checkmate.

While I had a lot of ideas this game, the battle only lasted 22 moves! That is the power of the pair of bishops – find ways to open the position and create static weaknesses, and at some point, your opponent will blunder under pressure.

I won’t have another tournament game until February 13th, at the Pennsylvania G/75 State Chess Championships, but this game is definitely an encouraging sign concerning the direction of my preparation.
