The Caro-Kann Advance is playable for both sides. With black, 3. ... Bf5 is undoubtedly best. 3. ... c5 was completley in the dustbend until starting out the caro-kann revived it. It's still a little shaky. You end up with a french minus some tempos, so 3. ... Bf5. There are 3 good moves.
4. Bd3 Bxd3 is easy for black. You just play for c5 and maybe f6 later to break up the center.
1. 4. Nf3 e6 5. Be2 play for c5
2. 4. h4 threatening to win a piece and gaining space. I play this some. 4. ... h5 seems to be best 5. c4 e6 if black plays dxc4 white gets an exposed d pawn on an open file. white on the other hand uses the e4 square for pieces with Nge2 and Ng3 Nc3 Ne4.
3. 4. Nc3 The most dangerous I always like 4. ... Qb6 (4. ...e6 5. g4 Bg6 is the main line) 5. g4 Bd7 White doesn't get the attack rolling against the exposed bishop. I think young Kasparov played 4. ... Qb6.
You really have to learn a little theory. This is just an overview. 3. exd5 cxd5 4. c4 drove me back to the french defense.
