1.e4 c5 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 g6 5.Nc3 Bg7 6.Be3 Nf6 7.f3 O-O 8.Bc4 Qb6 { This was my first outing with this opening and White has fallen into a small trap. } 9.Qd3? { A panic reaction. } ( 9.Bb3 to protect b2 has what looks like a problem after 9...Nxe4 but in fact White need not be too afraid of this continuation because of 10.Nd5! Qa5+ 11.c3 Nc5 12.Nxc6 dxc6 13.Nxe7+ Kh8 14.Nxc8 Raxc8 with equality. ) 9...Ne5 10.Qe2 Qxb2 11.Kd2 Qb4 12.Bd3 Nc6 13.Rab1 Qa5 14.Nb3 ( 14.Rb5 would have been better. ) 14...Qxc3+‼ ( 14...Nxe4+ 15.Bxe4 Bxc3+ 16.Kd1 Qxa2 would also win but not as beautifully. I spent a long time checking the queen sacrifice to make sure it was correct but my hand was still shaking and my heart pounding when I played it. ) 15.Kxc3 Nxe4+ 16.Kc4 Nd6+ 17.Kd5 ( 17.Kc5 makes the game finish even quicker after 17...b6+ 18.Kd5 Nb4# ) 17...Nb4+ 18.Kc5 Bc3‼ { The key move, trapping the White king in the middle of the board. White can do nothing to stop the Black b-pawn delivering checkmate. } 19.Bd4 b6# 0-1
