Annotated Game #185: Take those free tempi

This next tournament game continues the theme (from Annotated Game #184) of the value of a tempo.  My opponent at various times gives me a free tempo; in particular, 15. Qc1 is a turning point in the game, as I am able to then seize the initiative.  The value of the advantage of active piece placement is then demonstrated a few moves later, as various tactics hang in the air and my opponent misses a key square weakness.

The game also illustrates the strengths of the Caro-Kann Classical as a defense, as Black's setup allows his pieces to spring into action whenever White lets up the pressure; along those lines, see also the classic pawn break suggestion by Komodo on move 17.

Book completed: Mastering Opening Strategy


I recently completed Mastering Opening Strategy by GM Johan Hellsten (Everyman Chess, 2012).  The book took a beastly long time to complete - more on that below - but I think it was worth it, in the end.

Instead of a detailed theory of opening concepts, a la Ideas Behind the Chess Openings, GM Hellsten's book has four core chapters that center around a number of annotated games and long quiz sections, along with a short fifth one on opening preparation.  The chapters are:

1 - The Nature of Development
2 - Crime and Punishment
3 - The Battle for the Centre
4 - Restriction
5 - A Few Words on Opening Preparation

My comments:
  • Chapters 1 and 2 overlap a great deal, in the sense that pretty much all of the examples show how the less developed side is punished for neglecting opening principles regarding the value of rapid piece development.  A lot of them revolve around king-in-the-center positions, which you learn must be cracked open as soon as possible, otherwise the slower side can consolidate.  Piece activity (via development) and looking for opportunities to initiate attacks with early sacrifices, done to open lines in the position (especially towards the enemy king), are key elements that are illustrated repeatedly.
  • Chapter 3 is interesting, as in a number of cases the importance of the center is underlined by efforts on the wings to undermine it.  There are plenty of examples of seizing central territory with pieces and/or pawns and using that to dominate the opponent, though.
  • Chapter 4 is primarily about prophylaxis, with the focus being on limiting (sometimes severely) your opponent's piece development.  This is probably the most sophisticated chapter and underlines the importance of understanding your opponent's plans as much as your own opportunities.  A number of positional crushes are presented at the top levels of professional chess, showing that this really is an effective and important concept.
  • Chapter 5 contains some useful principles on building an opening repertoire, although does not try to be comprehensive.  Hellsten's observations on the opening being the most apropos area of the game for exploring your personal taste/style were quite interesting, especially in light of previous insights shared here on the concept of style in chess.  Basically the idea is that you should look at openings with structural and style similarities when building a repertoire, with a number of different types of factors highlighted.  This is not necessarily a new idea, but Hellsten explicitly focuses on the opening as most suitable for the expression of "style" choices and largely discounts it for middlegame play.
  • Be prepared for a long time factor in working through this book.  Each of the chapters has a number of example annotated games, which works well, then a large number of games (long fragments, sometimes complete games) as quizzes where you are supposed to identify the next move.  For example, Chapter 3 has 34 example games and 37 quiz games.  If you take them seriously and don't blitz through them, even going through relatively rapidly (say 5 minutes per example game and 10 minutes per quiz game), that means a typical chapter will take you around 540 minutes = 9 hours.  So that means around 36 hours total for the whole book.  So if you go hard at it for an hour a day, every day without a break, it will still take you over a month to complete.  I typically did study sessions in 15-30 minute daily chunks, not sequentially and with substantial breaks sometimes, so that meant it ended up taking well over a year to work through it.
  • If you're expecting a detailed, systemic exposition of opening theory and principles, this really isn't the book for it.  If you're looking for a number of well-annotated illustrative games with connecting and recurring themes related to the opening phase, then that better fits the description of this book.  Repetition of the themes has ingrained the basic principles in my chess thinking and should help me take better advantages of these types of opportunities in the future, even without retention of all the details.

Annotated Game #184: One tempo and the initiative

In this next tournament game, the role of the initiative is again highlighted.  As White, by move 16 I have achieved a great-looking position against my opponent's Dutch setup, but by a couple of moves later he is firmly in the driver's seat on the kingside, thanks to my losing the initiative.  I also make a critical mistake letting his knight into the e3 outpost, but then bravely (and somewhat desperately) sacrifice the exchange to get rid of it, in the hopes of eventual counterplay.  My opponent returns the favor later on, getting distracted and giving me a crucial tempo to let my queen penetrate his now-bare kingside, which gets me a perpetual and a draw.

It's interesting to see the importance of not wasting even a single move in tense positions and how quickly the initiative can turn - and then turn back.  It also yet again points out the importance of never giving up the fight until you are actually lost, with the game following a similar trajectory in that respect to Annotated Game #183.

What are your chess goals for 2018?

GM Gregory Serper has posted an excellent and relevant article "What are your chess goals for 2018?" over at Chess.com.  It's the season for New Year's resolutions, and he takes on several of the most common ones for chessplayers.  In particular, I found the below observation to be valuable in helping define how often one should play serious games:
2) Play more tournaments.
This is a very good resolution, provided that you use your common sense. It is difficult to get better in chess if you don't play serious over-the-board tournaments.  However, if you play a new tournament every single weekend and don't have time to analyze the games, it might be very entertaining experience, but you are not going to improve your chess much. 
Ideally you need to find a tournament frequency that will allow you to analyze the games, learn from your mistakes and play every new tournament as a new, improved self!
As mentioned in The Long Journey to Class A, over the past year I've found that playing tournament-level games on a monthly basis has let me strike a good balance between staying "warm" with competitive chess and offering enough time in between for meaningful study.

It was also a pleasure to see his reaction to the "gain rating points" goal:
When you set a goal to gain a certain amount of rating points, you shift your focus from chess to rating and therefore the fear of losing will ultimately stifle your creativity.
It's far better to set a goal of becoming a stronger player, ideally identifying the particular areas for personal improvement through your own analysis, and then let your rating catch up in its own good time.  Becoming a stronger chessplayer is fundamentally a lifestyle choice (establishing positive study/training/playing habits) and a longer-term commitment to excellence, rather than a quantitative goal.

My top chess goals for the year, in no particular order:
  • Integrate additional openings (or variants in my existing repertoire) into my play, by employing them in serious games, to help broaden the number of position-types that I'm familiar with and inject some variety into my game.  I've already started playing the Dutch Stonewall, to good effect.
  • Learn additional fundamental endgame positions by heart and delve further into the different types of endgame strategies (in rook endings, minor piece endings, etc.)
  • Make an effort to learn more comprehensively all of the typical middlegame structures and plans on a strategic level, so I better can recognize and apply them in my games.
