Past, Present, and Future

Hi everyone!  Apologies for a bit of an extended absence, the last weeks have been very busy for me (in a good way).  Three weekends ago, I played in a tournament up in Maryland as a warm-up for the VA State Scholastic Tournament two weekends ago.  Then, last weekend, I traveled to Schaumburg, Illinois – slightly west of Chicago, IL – to play in the K-12 High School National Championships.  Overall, there were many ups and downs, and probably more downs than ups all said and done.  Today, I want to share some sequences in a few of the games I’ve played recently that will hopefully provide some instruction for all of you.

We start with a big of a tragicomedy from the recent Nationals tournament.  In this game, I played White against Nikhil Kumar, a young 2370 rated player that I’ve played once before – however, in that game, I was Black, so this was new territory.  I was out of book early in the opening, but it went well despite no prior knowledge.  I eventually reached a superior position with a crucial decision ahead of me in terms of how to defend a piece.

I don’t want to let my d-pawn recapture on e6 if Black trades, so I wanted to defend my knight – the question was, how?  The two moves I came down to were either Re1 or Nfd4.  Each move has its benefits.  Re1 brings the rook into the game on the open file and threatens to penetrate deep in Black’s territory.  Nfd4 would ensure that a knight recaptures on e6, thus keeping control over a lot of squares that Black’s rook wants to go to, especially d8, and it would also avoid losing a tempo if Black tries to push g5-g4-g3 and attack on f2.  In the end, I believed that the pros of Nfd4 outweighed those of Re1 as I was especially worried about f2.  However, that ended up being the worse choice (although both were still advantageous).  According to the silicon engine, the best line was 21. Re1 g4 22. Nh4! g3 23. Kf1 and the evaluation is more than +2.  White can sidestep any fork threats and allow Black to capture on f2 while the rook and knight(s) feast on Black’s weakened kingside.  I missed the idea of Nh4, attacking f5 while preserving pawn structure integrity; instead, I only saw Nfd4 after g4, which would protect the f2 pawn at the cost of running into doubled pawns after the bishop captures on d4, but even this was apparently not that bad.  After all that, in the game, I managed to miss 21. … Nxe6 22. Nxe6 c6, after which I had to give up the advantage with 23. dxc6.

Later in the game, after much simplification and time scramble, I arrived at this position in the endgame with it being my turn.

Kobla – Kumar, Position after 36. … a5

Black just played 36. … a5.  It’s a clear draw after 37. gxf5, which keeps Black’s king near the kingside and I can just maintain opposition.  However, I managed to confuse a few different lines I had calculated and played 37. a4, which completely loses.  Granted, I had 6 seconds on the clock, but this was still going to be relatively simple to hold, as long as I played 37. gxf5.  After 37. a4, the win for Black is easy after 37. … f4, gaining opposition and putting me in zugzwang.  The game went 38. Kc3 Kc5 39. Kb3 Kd4 40. Kb2 Kd3 before I resigned.  I was definitely upset with myself after the game, but alas, life goes on.  In any case, the lesson to be learned is endgames, endgames, endgames!  I know for sure I will be trying to get back into studying endgames after this comedy of errors.  I know I’ve mentioned this before, but for those of you that are interested, I highly recommend Mark Dvoretsky’s Endgame Manual.

Another game of note occurred at the state tournament during the previous weekend.  Once again, I was White, but this time playing a lower rated around 1920.  After Black went out of book a few moves prior, we reached this position:

Mar23_KoblaGnanakumar
Kobla – Gnanakumar, Position after 19. Nf4

I just played 19. Nf4 to threaten Nxd7 followed by capturing on e6 to win a pawn.  At this point, Black played the tricky 19. … Ng4 with the idea that, if I take the knight on g4, Black will capture my knight on f4, and all I achieve is trading a pair of pieces.  However, I had seen this idea before playing Nf4, and I blitzed out 20. Qh3, to which he responded with the best (albeit ugly) move 20. … Nh6.  The critical move is 20. … Rxf4, after which I calculated the following lines:  21. Qxh7+ Kf8 22. Qh8+ Ke7 23. Qxg7+ Kd8 (23… Ke8 24. Qg6+ Kf8 (24… Ke7 25. Qg5+ Rf6 26. f4 with Nxg4 coming next) 25. Nxg4) 24. Qg5+ Qe7 25. Qxf4 and, in the end, I’m up an exchange.

A few moves later, we arrived at this crucial position after 24. … Qe7:

Mar23_KoblaGnanakumar2
Kobla – Gnanakumar, Position after 24. Qe7

There were several ways to progress, and I ended up choosing a move that was not objectively best, but it gave me a comfortable position I could play easily.  As a lesson, don’t always get caught up trying to find the absolute best move in a position.  While it usually helps, sometimes, the time spent on such efforts isn’t worth it.  In this position, I knew my position was better due to superior piece positioning, so I went for a simple variation – 25. Bxf5 exf5 26. Qf3 – that simplifies the position a bit and realizes the advantage of the two knights with many holes in Black’s camp.  I also saw the possibility of 25. Nxd7 Qxd7 26. Rxe6 Qxe6 27. Bxf5 Qf7, but as I was somewhat low on time, I didn’t want to risk losing too much time over trying to win a single pawn.  This approach of playing a comfortable move quickly ended up paying off as a few moves later my opponent blundered an exchange and the conversion was fairly easy.

Overall, as I did mention, my performance in these tournaments was less than ideal, but it just motivates me to work harder for next time.  Finally getting back to playing as also helped, and I hope that being more in touch will help me in the near future.  In other news, my last college decisions come out in less than a week, so I may have a better idea about where I might be going, and I might update you guys on that news next time.  As for now, good luck in your games, and, as always, thanks for reading!

Third Time’s the Charm: The Middlegame

After the first 3 rounds of the Southwest Class, I had 3/3, which included wins against 2 GMs. This was obviously a perfect start. However, in the next three rounds, aka the “middlegame” of the tournament, I got hit with some serious turbulence.

In round 4, I got black against GM Razvan Preotu (2522 FIDE, 2590 USCF). I lost a pawn out of a bad opening, but fortunately I had serious compensation. I scraped my way back to equality, and then…

Preotu 1

This knight endgame is slightly more pleasant for white, but black shouldn’t be in any trouble here, right…? I decided to activate my knight here with 45… Nf7, though 45… a5, preventing white from playing b4, may have been easier. After 46.b4, I made an inexplicable decision: I played 46… Kb6? allowing white to play 47.b5. I instead should’ve played 46… a6, and black really has no problems after that one. For some reason, however, I thought I should also be holding easily after my move.

Preotu 2

Now black is starting to get a bit cramped. Over the next few moves I continued to drift: 47… Kc7 48.Kc5 Ng5 49.Nf4 Ne4+ 50.Kb4 Ng5 51.Ka5 Kb7 52.g3 Kc7 53.Ka6 Kb8 54.Nd3

Preotu 3

Here I played 54… Ne4? which is officially a mistake. Instead, I had to play 54… Nf7, which ties the white knight down to the e5-pawn and takes the d6-square away from the white king if he plays like he did in the game. Black should be holding here, but after my move he’s in huge trouble. My opponent correctly played 55.g4! Ka8 56.b6 axb6 57.Kxb6 Kb8.

Preotu 4

After 58.Kc6 Kc8 59.Nf4, black is probably lost, since after 59… Ng5 60.Kd6, white is winning the e6-pawn. Instead, my opponent played it the other way around with 58.Nf4? Ng5 59.Kc6, walking into 59… Nf7! hitting the e5-pawn. If white retreats with 60.Nd3, black can simply play 60… Kc8 and white can’t get through. My opponent played 60.Nxe6 and offered a draw, which I accepted.

Phew! One of these days I’ll lose a game for playing like this, and it’ll serve me damn right.

3.5/4, 3 GMs and 3 foreigners down. Not bad!

In round 5, I got white against the top seed GM Jeffery Xiong (2666 FIDE, 2750 USCF). Rating-wise this game would be a tough order, but I had white and was in good form…

Xiong 1

So far, everything was all right. I didn’t get any advantage with white, but I wasn’t worse either. Still, there were a lot of pieces on the board, and anything could happen. After the best move 20.Be4!, improving my bishop and attacking the b7-pawn, the positon is around equal. I instead played 20.Bf5?! and missed the tricky move 20… Nh4

Xiong 2

I should’ve played 21.Bxb6, but I was worried about 21… Qxd1 22.Raxd1 Nxf3+ 23.gxf3 fxe6.

Xiong 3

This isn’t so pleasant for white, but in reality, the position isn’t far from equal after 24.Kh2 or 24.Re4 Nxh3+ 25.Kg2 Ng5 26.Rb4. Look what I did instead:

21.Nxh4? Bxd4 22.Qg4? Nd3 23.Red1 Bxf2+ 24.Kh2

Xiong 4

I admittedly missed the very strong 24… Rc4!, but even after a move like 24… Ne5 black is much better. After 25.Qf3 Qxh4 26.Bxe6 fxe6 27.Qxd3 Qf4, I went down pretty quickly.

Okay, what was that…? It was my first setback, and considering that I still had a 2600+ performance, I managed to brush this game off pretty easily.

In round 6, I got black against IM Omer Reshef (2491 FIDE, 2566 USCF). I didn’t hold back at all in this wildly complicated game. My silicon friend points that white did have a big advantage at a few moments, but to my human eyes, the position was just unclear.

Reshsef 1

Material is technically equal here, but white has a central pawn mass versus black’s b-pawns. There’s quite a commotion in the center of the board. And this was after the position calmed down a bit! I honestly wasn’t sure which result I was playing for, but I knew I had to act fast. I played the logical 23… Re6 but missed some details after 24.Qf4, after which I came to the conclusion that I was in trouble. I actually had 24… b5!, a move which I don’t think I even considered, at my disposal. Black has threats including Nxc3 Bxc3 Bd6 and Bb2. White is actually the one who has to play for equality with 25.Qd4! Bb2 26.Qxd8 Rxd4 27.Bd4.

Instead of that, I made a serious mistake with 24… Nxc3. The game continued 25.Bxc3 Bd6 (25… Rxe2 26.Qg4 g6 27.Rd7 Qc8 28.Qd4 is also unpleasant for black) 26.Qd4 Qg5

Reshef 2

27.Rd7! attacking the bishop would’ve given me a run for my money, since I simply won’t have time to take the e2-pawn. My opponent played 27.Rxb7 instead, which is strong but not best. After 27… Bc5 28.Qf4 Qxf4 29.gxf4 Rxe2 30.d4 Bd6, the dust settled.

Reshef 3

White is going to be a pawn up once he collects the b3-pawn, and he’ll have a dangerous passed d-pawn. This is far from easy for black, but it could’ve been worse. Though my play wasn’t the best, after defending for 55 moves, I managed to make a draw.

1/3 in this phase of the tournament wasn’t ideal, but it was a decent result given my opposition. I still had a 2600+ performance, was gaining plenty of rating, and was having a good time. Now all that was needed for a GM Norm was to maintain a 2600+ performance. By my estimates, I would need to score 2/3 or 2.5/3 in the last 3 rounds, which is obviously much easier said than done.

Next up, the endgame!

Winning the Atlanta Open (Part 2)

After winning my first game in a relatively quick manner, I found myself in an early tie for 1st place with 4 other people. Due to there being an odd number of people with 1 point, I found myself paired with NM Prateek Mishra who had ½ due to a first-round bye for round 2 with the black pieces. Having lost my last encounter with him several months ago similar to my first round opponent, I was committed to trying again to get my revenge.

Game 2: Black against NM Prateek Mishra (2206)

Here I was faced with a puzzling decision. I wasn’t sure how to activate either of my bishops without creating any serious weaknesses. However, I knew that if I was not able to develop, my position would quickly get steamrolled so I decided to weaken my kingside in order to gain coordination with my pieces.

After both sides being able to complete development and castle, I found myself conflicted. In this position, I had the ability to win a pawn with g4, but I was not sure if it would be a safe decision. While long-term, I would just be up a pawn and have a favorable endgame, the series of exchanges that would lead to me winning the pawn could result in the h file being opened up and my king could come under some pressure. Eventually, I decided that it would be safe to take the pawn due to me also exchanging the dark-squared bishop for my f5 Knight, which would remove a critical potential attacker.

After successfully winning a pawn I found myself in another tricky situation. Although I had a few options, I wanted to take the simplest course of action as I was very afraid of my king’s safety. Thus, I decided to play Qe8, which attacks the rook. I knew that this would lead to me either trading queens or winning an exchange.

Here, with my positionally slowly consolidating to me being up a clear pawn, I decided to play for a trick which, if executed correctly, could lead to me either winning an exchange or even a piece.

Be6 21. Nxc7 Rec8 22. Rc5 Bf8 23. Rc2 Bf5 24. Rc4 Bd3 25. Nxa8 Bxc4 26. Nxc4

With some incorrect play on my opponents part, I now found myself in the position to win a clear piece. However, I was afraid that if I played 26. Rxc4+ and Rc8 back later to win the knight, the position would be tricky to win. Instead, I found a cute simplification that would result in a position I felt more comfortable in my chances to win.

b5! 27. b3 bxc4 28. bxc4 Rxc4+ 29. Kd2 Rc8 30. Rh4 Rxa8 31. Rxg4+ Bg7 32. Rg6 Rf8 33. f3 Rf6

In this position, my opponent resigned. Exchanging rooks would lead to an easily convertible endgame up a bishop, and not exchanging rooks would result in me playing rook to a6 and winning the a2 pawn.

This win allowed me to stay in first place and was an overall interesting game. Although I was afraid initially for my king’s safety, with some precise play and simplification necessary, I was able to dilute any potential pressure to my king as well as later consolidate to a winning endgame. I hope this game was instructive and that you were able to learn something interesting out of it. On that note, until next time 🙂
