Caro-Kann Defense: Advance Variation, Short Variation: what should White play?

c3! — Excellent Choice!

✅ One of 2 top moves — you found a winning strategy!

Why this move is excellent: You recognized that the c2 was a point of tension. By playing c3, you solidify the center, provide a retreat for the e2, and prepare to challenge Black's structure. It is a sophisticated, prophylactic choice that most players overlook!

Multiple Valid Strategies

Different paths, same destination: While 60% of humans instinctively choose to castle with O-O, your choice of c3 is actually the engine's favorite! Castling is the "natural" developmental path, but your move is more precise, addressing the pawn structure before Black can create counterplay against the c2 square.
