The disadvantage from your miss was due to being down the important d5 pawn. Basically, in the caro kann, the d5 pawn is the pride of your position. You prepare pushing it on move 1, and almost always support it with e6. Not to mention, it's your only pawn in the center. My reccomendation is to try not to get into central complications before castling, and also try not to hang pawns. Your main idea in the exchange caro should be the minority attack (Rb8, b5, b4, bxc3 and putting pressure on the queenside). You can study S&Ss on chessable to improve your caro knowledge.
Thank you so much for the detailed advice! I really appreciate you taking the time to explain the importance of the d5 pawn in the Caro Kann. The idea of executing an attack with Rb8, b5, b4, and bxc3 in the exchange variation is a strategy I'll work into my game. Thanks for the tip on Chessable💪🏻
@@mokertho It's my pleasure. I always enjoy helping people go through the same things I went through, especially as I played the caro for most of my rating climb.
