Annotated Game #356: Cramped to death in the endgame

This next tournament game features what should have been a comfortable draw as White in a King's Indian Defense (KID) by transposition - with some opportunities for advantage passed up along the way - but which devolved into a highly cramped loss. The key error, if not the final losing one, was exchanging queens on the c-file to reach a cramped minor piece ending. This was simply unnecessary and reflects a repeated tendency I have to worry excessively about an open file with an opponent's major piece (queen/rook) on it, even if I have all the penetration squares effectively under control. My opponent does an excellent job of demonstrating how squeezes can happen in endgames, although I had opportunities to relieve the pressure with an f-pawn break. Very instructive.

Annotated Game #355: The Stonewall does its job

After an unfortunate loss in the first round of the tournament and barely escaping with a draw in the second, in this next game I was satisfied enough with a relatively easy and clean draw against a higher-rated player. I transposed into a Modern Stonewall as Black and achieved equality early on, which was the job of the opening to accomplish, but I missed a couple of chances to press for a clear strategic advantage. My opponent did well to disrupt my plans with 12. Qb3! and this lesson should help me keep a better eye on tactics along the g8-h2 diagonal in the future.

Annotated Game #354: Learning the Staunton Gambit the hard way

In this second-round tournament game, as a relatively new player of the Dutch Defense, I faced my first Staunton Gambit. Although it is now considered somewhat theoretically deficient for White, it is still dangerous if Black is not fully prepared. This fact is well-illustrated below, as I confuse the necessary move 4 response with that for other lines in the gambit. White as a result gets exactly what he wanted out of the opening, including a clear pawn-up advantage. In the early middlegame at first I am barely hanging on, but after sorting out my pieces I am able to target my opponent's vulnerabilities and gain equality, after some interesting tactics (including a big missed one for White). I was happy to reach a fully drawn position and will certainly remember more of my prep for the next time I see the Staunton Gambit.

The engine validates the 0.00 evaluation and I had a lot less time on my clock, plus was tired enough from defending to mistrust my ability to try to press for a win with the two bishops.} 1/2-1/2

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.
