# Open SicilianEdit

Black's 2...d6 gives him the option of several popular attacking lines, controls the e5 square, supports the c-pawn and activates his queen's bishop.

White's rationale for playing 2. Nf3 was to support a 3. d4 advance which he may now play. His best alternative to this, for rapid development, is 3. Bb5+, forcing Black to block the check with a minor piece that would then be pinned to the king. Swashbuckling players might be tempted by 3. b4, planning an unopposed d4 when the Black c-pawn is diverted to b4.
