Annotated Game #369: Play it again, Caro-Kann Exchange

In this final-round tournament game, I again had the experience of my opponent duplicating an opening from a previous round (Annotated Game #367), this time with me as Black in another Caro-Kann Exchange variation. While I normally do not conduct a full game analysis until after a tournament is done, while playing I do make a point between rounds of entering games into my personal database and running through them, both to capture my thinking process and identify any obvious problems that need correcting. I was therefore confident about my preparation in this variation, although my opponent ended up surprising me with 8. Ne5!? This lead to easy equality and a rapid liquidation into a drawn major-piece ending, which I considered a good result as Black against a higher-rated opponent. Two clean games in a row was also a good way for me to finish out the tournament.

Black more often plays ...Bg4.} 7. Nf3 Bf5 {posing the question to White of how to continue - exchange on f5 or continue with development.} 8. Ne5 $5 {the first time I have seen this. White neither exchanges nor develops, instead moving the knight a second time, to the e5 post. It is the third-most played move in the database, however.} Bxd3 {following the normal rule to exchange on d3 if White fails to exchange on f5.} 9. Qxd3 Bg7 $11 {there is no better square for the bishop, and Black has achieved equality without much effort.} 10.

Nd2 {this made me wonder if my opponent was considering queenside castling.} Re8 {the rook typically belongs on the e-file, or at least not just sitting on f8.} 13.

Nf3 e5 {I expected this would result in a general liquidation of pieces.} (14... f6 $5 {would insist on changing the pawn structure, not just prompting a series of exchanges. However, the position would remain equal, per the engine.} 15. Qd2 (15.

Qe3 {At the time I felt this unnecessarily saddled White with a weak e-pawn, but the position is still completely drawn.} Qxe3 21. fxe3 Kf8 {I thought for a while here and decided that I would first prioritize king activity in the center. White only has the half-open f-file for his rook, while I have a choice about where to place mine.} 22. Rd1 Ke7 23. Rd4 f5 {I thought for a while here and this is fine, if perhaps not ideal.} (23...

Meanwhile, White has no exploitable weaknesses either.} 28. cxd5 cxd5 29. b4 {and I accepted a draw offer, judging that the position was completely even. My opponent was much lower on time, although not in any immediate clock trouble.} 1/2-1/2
