The Anti-Caro-Kann Defence arises after 1.e4 c6 2.c4. ECO code: B10.

White plays 2.c4, controlling d5 from the side and steering the game away from standard Caro-Kann structures into English Opening-type territory. After 2...d5, the game may transpose into Panov-Botvinnik structures (3.exd5 cxd5 4.cxd5) or maintain an independent character.
