Caro–Kann Defence: 1.e4 c6 2.d4... 3.Nc3 - Opening Moves
Summary

The Caro-Kann Defence: 1.e4 c6 2.d4... 3.Nc3 arises after 1.e4 c6 2.d4 d5 3.Nc3 and falls under ECO code B15. White brings the knight into play, preparing to recapture on e4. The principal continuation is 3...dxe4, which eliminates White's two-pawn center, and White typically responds with 4. Nxe4, though certain gambit approaches involving declining the recapture also exist.
