Black gets three pawns for his piece, and an attack [ White may have been contemplating something like: - 9...Nh6 10.Bxc4 dxc4 11.Nxc4 Qc7 12.0-0 Nxb4 13.Nd6+ Bxd6 14.exd6 Qxc3 15.Bd2 Qc6 16.Bxb4 Nf5 17.Ne5 ]

10.cxb4 Qxb4+ 11.Ke2 Bxa4 12.Qd2 c3 13.Qa2 Bb3 14.Qb1 Qa4 15.Ke3 Nh6 16.Bd3 Nf5+ 17.Bxf5 exf5 18.Qxf5?
White has allowed himself to be diverted by a pawn sacrfice [ 18.Re1 Rather better was to attempt artificial castling 18...Be7 ( 18...Bb4 19.Nc2! ) 19.Ke2 Bc4+ 20.Nxc4 Qxc4+ 21.Qd3 Rc8 22.Qxc4 Rxc4 23.Ba3 Bxa3 24.Rxa3 0-0 25.Rc1 Rfc8 26.Kd3 ]

18...Be7 19.Ng5 Bxg5+ 20.Qxg5 0-0 21.Nc2 Qd7! 22.Ne1 f6
White is lost
