Caro-Kann Defence: Classical Variation B18 Caro-Kann Defence 4... Bf5 · Caro-Kann Defence: Classical Variation The Classical Variation. Black develops their bishop and attacks White's knight on e4. White often sticks to the main line with /5. Ng3/, forcing the Bf5 back. However, other options exist. The aggressive Burris Gambit, /5. Bd3/, has given White surprising success and the interesting /5. Ng5/ is an aggressive move, often aiming to play the Martian Gambit. Other moves are generally not very good. 5. Nc3 retreats the knight to where it was before, while the ambitious 5. Nc5 is perhaps too aggressive and the knight can be kicked away easily, while 5. f3 defending the knight is playable but White will have to be careful to not weaken their kingside.
