Annotated Game #63: Third time's the charm (?)

The first game of my next tournament is already covered in Annotated Game #3: Attack of the Clones (as the original, not the copy).  The second game isn't quite a clone, but it is yet another disappointing example of turning a Caro-Kann into a French (see Annotated Game #47).  If the practice of analyzing a game a week for this blog does nothing else for my game, it will ensure that I never do this again, this being the third time I have seen this error.  Let's hope there's not a fourth one lurking out there...

Unlike the previous efforts, at least I managed to secure a draw in this game.  White's cramped 7. Nd2?! development probably gets most of the credit for this, as does his failure to find a recurring tactical theme of trapping my light-square bishop on the queenside.  Black's setup isn't horrid, but it lacks counterplay until White allows some maneuvering by the Nc6.  The final position is interesting, as White's rooks are cut off from each other and Black ends up chasing the one on the 7th rank around.

Some lessons learned from the analysis:
  • Never get off the boat play ...e6 in the Caro-Kann Advance when there's still a chance to meaningfully develop the light-square bishop.
  • Properly evaluate the effects of minor piece trades, to ensure that you're not getting the worse end of the deal (move 9).
  • Look for the most active square for your minor piece and place it there (move 14).
  • Be wary of taking away squares from your own advanced pieces (moves 18-19)

  1. The comment on 13. a3 for white is interesting. I read so many beginner books advising not "wasting time" with moves like this it took a lot of experience to realize how useful this is to restrict the Nc6 when there is nothing urgent going on elsewhere.
