About the Caro-Kann Defense
Black answers 1.e4 with 1...c6 and then ...d5. It is like the French, but the light-squared bishop can come out first.
Black often plays ...Bf5 or ...Bg4 before closing the position with ...e6.
The pawn structure is very solid, so Black rarely gets mated early.
Black later frees the position with ...c5 or ...e5 and aims for a good endgame.
