Annotated Game #271: Play what you know - or at least what your opponent does not

The first round of the next tournament I played featured a poor strategic choice on my part. I hadn't properly prepared the opening (a Caro-Kann Two Knights) so was afraid to enter into my own repertoire line. Instead, I chose to play the main line - having no real experience in it - and handed my opponent a big lead in development, positional plus and an early attack. My deficient understanding in the line was bad, but really the strategic opening decision was even worse, choosing something that logically my opponent would have more experience in, rather than "risking" entering into my own repertoire sideline, which it was much less likely my opponent would know, even if my memory was also faulty.

Showing the value of not giving up early, analysis identified where I objectively got back in the game (and could have even achieved counterplay, with some active choices). However, my opponent did not give up her attack either, and eventually broke through. A well-deserved win on her part.

Book completed - American Grandmaster: Four Decades of Chess Adventures

 

I recently completed American Grandmaster: Four Decades of Chess Adventures by GM Joel Benjamin. I had picked it up as a bargain used book from a dealer at chess tournament a while back, and finally decided to read it during lunchtime at work, my interest primarily being for daily annotated games review. It was not particularly well suited for this, however, as the majority of the actual chess content consisted of individual positions, game fragments, or complete scores but with only a couple comments included. There were enough games at a sufficient level of annotation to be worth going through, but this was a minority of it. If you are looking for something more comprehensive and challenging for annotated games but still with a personal perspective, My Best Games by Victor Korchnoi is world class, while GM Walter Browne's The Stress of Chess...and its Infinite Finesse is a much more detailed and improvement-oriented version of a chess career book with well-annotated games.

From my perspective, it seems the book tried to be multiple things, but was mostly a breezy and candid, but not quite a tell-all, recounting of GM Benjamin's chess career. This mostly consisted of complaints (and occasional praise) about tournament conditions, memories of poor treatment (or occasionally special experiences), and chess politics. The Deep Blue vs. Kasparov project got an interesting treatment and GM Benjamin's perspective was certainly unique, although the narrative was not exactly comprehensive. The book was published in 2007 but the focus was on Benjamin's junior and earlier career, really through the 1990s. As such, a lot of the references - especially to the politics and various failed professional associations - feel quite dated. If you weren't around the 1990s, therefore, it's probably not going to be particularly relevant.

Annotated Game #270: Learning the Slow Slav the hard way

This last-round tournament game is yet another example of the main lesson from Annotated Game #267: How openings are really learned. Here it's a Slow Slav that I had little depth on previously, but studying this game and looking at a couple database examples now have armed me much better for future clashes in the opening.

Annotated Game #269: Symmetrical = wild??

Due to having a bye round in the tournament (and having quickly lost my first game as Black), I surprisingly ended up having two Whites in a row. This one, despite being a Symmetrical English, turned into one of the wildest games I have played in at least the past few years. 

Similar to Annotated Game #265 and others, I often get the sense from my opponent's initial hesitation to respond to 1. c4 that they have decided to simply mimic moves, rather than actually follow a prepared repertoire. The problem from White's perspective is that in this opening, that works reasonable well for Black up until around moves 8-9. The positive aspect, as I've also learned, is that once asymmetry is reached, Black may have less of an idea about what to do in the middlegame.

In this game, Black's asymmetric move 9 allows White to obtain a small positional plus and led to what could be a comfortable, even winning middlegame. One of the main lessons for me was a failure on move 14 to kick Black's strong centralized knight on d4 - this is something that I recognize I have repeatedly failed to do in other games, also with poor results. A big benefit of analyzing your own games is recognizing these types of specifc patterns that recur and then correcting them; I articulated this in more detail in Annotated Game #192: The problem of mental perspective. 

Starting on move 17 the game gets a lot crazier and mutual time pressure contributes to a number of swings in evaluation. I wish I had been able to spot the more sophisticated way to play, but felt relatively good at the end of an exhausting wide ride, escaping with a draw.
