Annotated Game #353: Striking the second-best blow is not enough

In this first-round tournament game, I achieve an ideal Colle-Zukertort attacking formation as White out of the opening and nearly put my opponent away after a couple of his inaccuracies. However, my initial attack failed to fully connect as I could not find the knockout blow. The second-best move (according to the engine) was enough to keep up the attack's momentum and give me a second chance, but again I failed to find the key idea, which was to shut down my opponent's queenside counterplay possibilities first, before returning to prying open the h-file. My opponent did not give me a third chance and recovered well, taking advantage of an open White backfield to first infiltrate his queen, then decisively with a rook. A valuable game to study for lessons in attacking dynamics and strategic prioritization.

Training quote of the day #66: Junta Ikeda

 From IM Junta Ikeda's Substack post "Deciding to play" on his mindset for tournaments:

Acknowledging that you’re going to make mistakes and potentially lose, even if you play your best, takes some pressure off whether you’re the top seed or bottom seed. It’s not necessarily a mechanism for defending yourself in advance from painful losses, ‘unlucky’ results or having excuses ready. It’s being objective and accepting that chess is a hard game and it takes a lot of time and tournaments over months and years to know more about yourself and your chess. And there will be many painful losses and tournaments, but you’ll keep learning and adjusting with each one.

Annotated Game #352: Simul vs. GM Ben Finegold

This simul game, played versus GM Ben Finegold at this year's National Open in Las Vegas, ended up in an exciting finish. As with other GM simuls I've played in, I was able to do well with my opening prep, studying published games and focusing on the most likely lines I would face. GM Finegold has publicly touted the Torre Attack setup versus the Dutch Defense, and we in fact enter that, following some other games in the database until around move 8. In the middlegame, I make some awkward, piece-restricting moves that GM Finegold takes advantage of positionally with easy, harmonious development, which is instructive to see. The end becomes wild as I boldly (finally!) emphasize piece activity for practical chances and could have drawn (or even won), but was not able to find the more subtle solutions, and White then wins with an aesthetic discovered checkmate.

Book completed - Chess Duels: My Games With The World Champions

 

I recently completed Chess Duels: My Games With The World Champions (Everyman Chess, 2010) by GM Yasser Seirawan. As part of my study/training process, on a daily basis at lunchtime I normally work through a book of annotated games, ideally written by a master-level player that showcases their internal thought process. There are of course a number of good "Best Games" type books out there - including ones I've previously completed - but I found this one to be uniquely valuable in several respects:

• Seirawan includes all his career games with the world champions he played against, not just the best ones, which immediately differentiates this collection from others. While in fact he has an excellent competitive record against them, some of the games (win, loss or draw) inevitably feature his blunders and bad decisions. This balance makes the book even more valuable for instructional purposes, since he can provide firsthand explanations of not just why moves (or evaluations) were incorrect, but the thought process behind the choices. It also serves to humanize and normalize even his bad play, which of course we can all relate to from our own experience, making us feel better about chess.
• The background stories he shares about himself and his opponents are similarly humanizing and provide interesting context to the games. I found the content overall to be appropriately balanced and largely focused on chess-relevant themes, rather than trying to be too biographical. He had particularly fascinating accounts of some of the behind-the-scenes activities of Fischer and Kasparov.
• While the events of international chess politics are of course historically dated (through 2010), this is still the best review and set of insights into those World Championship-level issues that I've seen. Personally one of the reasons I was turned off from an interest in tournament chess for a number of years after college was the interminable series of Kasparov-Karpov matches, which were followed by a fragmented, confusing and opaque world championship process. Seirawan provides an insider and largely objective viewpoint on all this, without letting it become too much of a rant.
• For those familiar with his live commentary style, Seirawan's authorial "voice" is similarly clear and well-organized, as well as being appropriately humorous (often self-deprecating) while still taking his subject matter seriously.
• Factors that were behind historical world championship controversies are still relevant to what we see in today's top-level chess scene, as evident in the following excerpt, where Seirawan comments on Garry Kasparov's retirement from competition in 2005:

Kasparov's retirement left the chess world in a sad state. It was denied the joy of seeing Kasparov play, and the World Championship title itself no longer seemed to have legitimacy. After all, the title only meant something if chess players around the world thought it did. With multiple and ever-changing Champions, and shorter and shorter matches, the chess world could really only look to the rating list to determine who was "number one."

Annotated Game #351: Completing a trilogy of ugly wins

This final-round game is another ugly win, making a trio for the tournament. I felt better about it than the others, however, since the middlegame was more interesting and I got into a losing position only after missing an excellent attacking continuation at a critical point (move 25). After that, I needlessly panicked as White got the initiative, then landed some hard blows against my position. My practical decision-making was good, however, in that I kept posing White problems, which eventually he failed to solve in the best way, thereby letting me back into the game. The denouement comes after a crucial bid for counterplay is allowed to succeed by White, then I force a transition into a winning queen endgame.

Nd4 Qg4 {awkward, but I wanted to maintain the protection of the Bc8.} 39. Nb5 $2 {my opponent ignores my counterplay possibilities with the queen.} Qg5+ {played with a great sense of relief. Now it is White who can easily miss the right continuation.} 40. Kd1 $2 (40. Kc2 $11 {this is the only move that does not lose.}) 40... Qxh5+ 41. Ke1 Qxb5 $1 $19 {now c8 falls but after the dust settles, I have a won queen ending.} 42. Rxc8+ Nxc8 43. Qxc8+ Kxg7 44. Qc7+ {these endings are always tricky and I have managed to draw them myself when theoretically lost. The trick to win is normally to force an exchange of queens into a won K+P ending. This can take a lot of maneuvering, however, especially (as in this case) when both kings are open to checks from the opposing queen.} Kg6 45. Qd6+ Kf5 46. g4+ Kxg4 47. Qg6+ Qg5 48. Qxe4+ Kg3 49.
