I switched from the Sicilian to the Caro-Kann mainly because of the boring c3-Sicilians (another thread?
) I had to play against and the amount of theory where you just have to do your opening homework.
Although at this moment I have only played blitz games with the CK, the games I get are always interesting and fun! One part of the fun aspect is due to the freshness of playing a new opening, but the positions are always imbalanced and there is always room for creativity.
The imbalances which are present in most variations is one of the things which attracts me to the Caro-Kann. There are few Kill-All-The-Black-Fun variations for white such as the c3-Sicilian or the Exchange French. I think you have more chances to outplay (or be outplayed...) your opponent in the CK in the minor variations.
The other thing is the reputation of the CK. When I told my teammates I was going to switch to the CK the first response was "Oh? To get a draw?".
The CK has the reputation for boring play and for players who like a quick draw with black. That reputation already gives you a plus in the opening if you just want to play chess and play for a win!
As a former Sicilian player I love it when white goes all-in in the not so solid Nc3-Advance variation
@Pingudon The CK is still solid in most variations, but not that passive. Wells has written a nice overview of the CK if you would like to check it out.
