Bxc6+ bxc6 7. d4 Nxe4 { Black hopes to maintain the knight here to use as the basis for a kingside attack.} 8. Qe2 f5 9. dxe5 d5 10. Be3 {With Black still at least two moves from castling White should either try to undermine Black's knight by 10. Nfd2 and f3 open the center by 10.c4.} 10... c5 11. c3 { A consequence of his previous passivity, but now Black has the initiative.} 11...
