Annotated Game #251: Repeated patterns and learning through analysis

This first-round game was played nearly a year after my previous tournament experience (Annotated Game #250), so I expected to have some mental rust and was not disappointed in that regard. It is a hard-fought game nonetheless, against a high Class A opponent, and provides a number of valuable lessons through analysis. One recently-highlighted pattern in my play is the failure to adequately contest open files, particularly the c-file as Black, which plays a central role in the strategic element of this loss; see also Annotated Game #242. It's this sort of revelation that makes analyzing your own games such a useful practice.

Other useful highlights:
  • A simpler way for Black to meet this sort of London System / Exchange Slav setup is given on move 5.
  • Neither side benefited from moving their f-pawns in the early middlegame. For me as Black, it was an erroneous strategic idea, as my play should have been focused on the queenside and center, given the structure. The classic "pawn-pointing" theory of determining which side of the board to play on works here, with my f7-e6-d5 pawn chain.
  • Stubborn defense has its rewards, as I fought hard in a strategically lost position and created the move 51 opportunity to reach a drawn position.

Nc5 a5 {this at least is a correct idea, fighting for space on the queenside and being happy to open the a-file for my rook if White seeks an exchange.} 20. a4 b4 {Komodo rates both this and the pawn exchange equally. With White having a better-placed knight, I thought it was better to seal the queenside rather than open it up. It should also simplify planning.} 21. Rc2 Ne4 $6 {yet another move by this knight instead of mobilizing the a8 rook, which now has nothing to do. This ends up giving White too much control over the c-file, although it is not yet decisive. It also creates an additional pawn island for Black.} (21... Rac8 $5 $11) 22. Nxe4 $14 fxe4 {we now have a Dutch structure with queen and rooks. From playing the Dutch, however, I should have better known that when there is an open c-file, this favors White.} 23. Rfc1 $6 (23.

Now instead White has the initiative.}) 24. Rc6 {my opponent does a good job of identifying the most vulnerable target in my camp.

Training quote of the day #32: Artur Yusupov

 From Training for the Tournament Player by Mark Dvoretsky and Artur Yusupov

What enables a chessplayer to be successful? In response to this question two essential factors are usually singled out: talent and hard work. But it is not sufficient just to be talented and hard-working. Physical condition, competitive character and the ability to concentrate during play are also very important. No less important is the ability to choose correctly the decision that such work should take and to be able to reach the required standard. Needless to say, this task is far from easy...

Of course, in order to be able to choose a direction leading to self-improvement it is necessary to have a critical understanding of one's game. The authors are totally convinced that the serious study of one's own games is an essential requirement for any chessplayer who wishes to improve. Therefore the theme 'analysing one's own games' occupies a central place.

Annotated Game #250: Learning an opening the hard way

This final-round tournament game is an excellent illustration of how most new openings are learned: the hard way. Learning openings is not really about memorizing variations, it's much more about knowing the standard early middlegame plans and how to handle common tactical and positional themes. 

In the Dutch Stonewall, one theme is the pawn exchange on d5, if White initiates it. The usual rule (retake with the e-pawn rather than the c-pawn) applies here, and as Black I get a comfortable game out of the opening. The next key move occurs in the early middlegame, on move 11, and is the main teaching point: the potential power of the White pin on the a2-g8 diagonal. Here I ignore it and it makes itself felt immediately, then also later in the game on move 21. There are other useful lessons and observations that I got out of analyzing this game, but now I'll be very sure to recognize that theme in the future.

Nc3 O-O 8. cxd5 exd5 {the general rule for an exchange on d5 in the Stonewall is to recapture with the e-pawn.

Bad chess attitudes #3: My losses are too painful; everything is good in my wins; draws are just boring; so no need to look at my games

I'm highlighting in a short series of posts some bad chess attitudes that can harm our performance and hold us back from improving. To avoid being seen as too judgmental, I'll only share ones that I've struggled with myself.

Bad attitudes #1 and #2 both involved reacting in an unhealthy manner to your opponent's choices - in openings and time management, respectively - which in turn meant not focusing not enough on your own play. Here, it's about your game results and what you do with them.

Bad attitude #3 (expanded version): my losses are due to blunders too painful to look at; everything must have been good with my wins; draws are indecisive (and boring); so there is no need to analyze my games afterwards.

The above sentence I think sums up well my own (superficial) attitude about my games for the majority of my chess career, starting at the scholastic level. This sort of reaction to our results I believe is fairly common and is even understandable, while unproductive.
  • It is in fact difficult to relive losses, especially ones involving painful blunders. This is the first hurdle to get over. Giving yourself a bit of time before fully reviewing the game can help, as after a day or a week the emotional reaction is lessened and you can look at the game score more objectively.
  • A certain amount of work and energy is necessary. This means saving full game analysis until after a tournament, for example, when you are more hungry for chess again. Recording some initial comments and thoughts can help capture your thinking process in the moment - a good time for this is while you are putting a game into your personal database - but it will be more productive to save the heavy lifting for later.
  • Feeding games to an engine in order to see where you and your opponent blundered, then filing them away does not count as analyzing your games. This was part of my own practice for over a decade of non-improvement (see "The Long Journey to Class A"). It is now even easier to do this, thanks to the capability for near-instant "analysis" of games on major chess sites (such as Chess.com). In reality, this consists of a single engine pass that evaluates positions at a relatively low ply (move) level. This may have some use as an immediate blunder-check tool, along with its entertainment value; however, judging from public comments, many players take it far too seriously.
  • Your wins and draws contain just as many lessons for improvement as your losses. Serious work will reveal flaws in your wins, sometimes even more so than in your losses. (This may be part of why people avoid performing an objective analysis of all of their serious games.) It will also highlight strong moves and ideas that you found, as well as general patterns of your strengths and weaknesses over time. This type of self-knowledge and increased chess understanding cannot come from any other source.
The basic problem with bad attitude #3 is that if you keep on doing the same things without understanding why, you will end up getting the same results. "Why don't I progress if I play a lot?" is a common refrain. I do think that relatively frequent play, especially with opponents near or (ideally) somewhat above your current level, is necessary for improvement. Once you reach a certain point where simply playing more is not teaching you enough, however, it is time to go deeper in your understanding of chess, which of necessity includes analyzing your own games

Video completed: "Why You Should Always Have a Plan" by Tatev Abrahamyan

 

"Why You Should Always Have a Plan" is the seventh video in the Chess.com series by Tatev Abrahamyan. I've resumed going through them after being distracted by various things. The main point of this lesson is to continue to actively plan at all stages of the game, including while playing with a winning advantage. In other words, don't just assume that once you achieve a comfortable position, even one where you should win, you can just coast for the rest of the game.

The first example game is Akobian-Caruana from the 2017 U.S. Championship. Caruana is up two connected passed pawns in the late middlegame, which should be enough to win. A apparently careless move by Black drops a pawn, then after a rook exchange they end up in a Q+N endgame with just the one extra passed pawn for Caruana - which again should be enough to win. Black passes up a chance to grab back a pawn and then White is able to get an annoying pin on his knight. Getting out of this, Black opens himself up for a knight sac tactic that would result in a perpetual check. White did not in fact play this, which turns out to be lucky for him, as later Black blunders and drops his knight, losing. It's not mentioned whether the two are in time trouble or not - which seems likely - but the game is still a good illustration of why even strong players cannot simply go on autopilot with what should be a winning advantage.

The second game is GM Alejandro Ramirez vs. GM Le Quang Liem, from round 5 of the 2019 Gibraltar Masters tournament. Abrahamyan points out how White followed an incorrect plan in the early middlegame starting on move 15, moving his knights without much purpose around the queenside instead of focusing on available kingside targets, with complex play. The outcome was poor placement of the White knights and giving some free improving moves for Black, who then was able to target White's weaknesses and collapse his position relatively quickly.

The final example is FM Carissa Yip - FM Annie Wang from the 2019 U.S. Women's Championship. Abrahamyan highlights how well White has set herself up in this Classical Sicilian, but in the middlegame she does not find a good plan to go from there. Black in contrast has a clear plan to play on the queenside, attacking White's castled king position. White decides to force the issue in the center, where she has built up her forces, but the resulting exchanges actually give Black better central pawn control and free up her pieces as well. The resulting attack is instructive, with Black bringing all her pieces into play while White's pieces all end up on the kingside, providing little help.

In each example game there are opportunities to pause and look at some key positions, which helps make the lessons more engaging beyond the overall theme, which underlines how drifting planless in the middlegame (or endgame) is a bad idea.
