9.Qd2! correcting judging the b-pawn would be tough to swallow [9.Bxf6 Bxf6 10.Nd5 Qa5+ (10...Qxb2? 11.Rb1 Qa3 12.e5!! cutting off the bishop from protecting the a1 square /\12...dxe5 13.Ra1 Qb2 14.Ra2+- ) 11.Qd2 Qxd2+ 12.Kxd2 Bg7= ]

15.Nd1?! White won't get the light bishop out of harm's way, but Black also won't capture it [15.Ba2 b4 16.Nd1 h6-/+ ]
