In a Caro-Kann pawn structure white has a 4 - 3 queenside pawn majority. 17.e5 was the correct pawn break, as it eliminates whites queenside pawn majority. If you had played 17.c5, white would have traded down to a 3 - 2 pawn majority, which helps make it easier to create a passed pawn in the endgame. Obviously this is not a hard and fast rule, but "generally" the ...e5 pawn break is preferred for the reasons i mentioned.
After reading what mickynj rote, i had to come back and add that i am in total agreement with his comment. Considering the rating you said you have, you played very well.
Hi all,
Here is my latest game which I would like to share with you and would be glad for any analysis and suggestions on how I could improve my game. I was Black and lost against a 1300 player (I am 1100).
In the end I had less than 2 minutes on my clock.. The moves I lost too much time on was 11Re8 (28 minutes!, because I was afraid of the Bishop sacrifice at h6 and was thinking to play either g5 or Kh7) and 12 Qc7 (16 minutes!, because I was thinking too much of playing Qb6 attacking the b2 pawn but eventually I was seeing it was not working).
After the game with the help of the engine I see that on move 17 I should play the break c5 (and not e5), as I understand in order to keep the pawn chain at the kingside intact. Also in move 18 I did not even consider Nd5 (there I would also attack the Bishop and the Knight would also be protected). Also in move 21 Bxa7 I did not even think of him taking the pawn (most probably due to the time issues, but also I tend to forget such vulnerabilities in middlegame to endgame phase).
