After 13.a4 O-O 14.axb5 axb5 White would be well developed and Black's b and h- pawn would become objects of attack. For this reason Black's last move was not as good as Be7.} Nc4 14.Qe2 {If Qc1, Rc8 might follow threatening Nxb2; this move would also be strong against Bc1, and Rb1 would be answered by Nxb2 at once. White now begins to complicate matters, in order to make an attempt of saving himself.} Nxb2 15.Ne4 Bxe1 16.Rxe1 Nc4 17.Ne5 Rc8 {By 17...Nd6 Black could have repulsed the attack. After 18.Nxf6+ gxf6. 19.Nxf7 Kxf7 neither 20.Qxe6+ (Kg7) nor 20.Qh5+ (Ke7) would lead to anything. After the text the sacrifice is correct and leads to a draw.} 18.Nxf7 Kxf7 19.Nxf6 gxf6 20.Qxe6+ {But now he ought to play 20.Qh5+. If Ke7 21.Bxf6+ Kxf6 22.Qh6+ Ke7 23.Qxe6+ and draws by perpetual check. If 20...Kg8 21.Bh6 White's position would be good enough to win. If 20...Kf8 21.Qh6+ Ke8? 22.Rxe6+ Kd7 23.Bf5 Black would stand on a volcano.} Kg7 21.Bh4 Re8 22.Qg4+ Kf8 23.Rf1 Rc7 24.Qf4 Rg7 25.f3 Re2 26.Rf2 Re1+ 27.Rf1 Rxf1+ 28.Kxf1 Kf7 29.Bg3 Qe7 30.Kf2 Bd5 31.Bf5 Nb6 32.Qb8 Nc4 33.Qf4 Qd8 34.Bg4 Qa5 35.Kg1 Qb6 36.Kh1 Be6 37.Bh5+ Ke7 38.Qh6 Rf7 39.Bf2 Qa5 40.d5 Bxd5 41.Bxf7 Bxf7 42.Qxh7 Nd6 43.h4 Qxa2 44.Bg3 Qd5 45.Qh8 Ne8 46.Qh6 Qc5 47.Qd2 b4 48.Qe2+ Kf8 49.Bf4 b3 50.Qb2 a5 51.g4 a4 52.Bc1 Qe5 53.Qd2 Bd5 54.Kg2 Nd6 55.Bb2 Qe6 56.Kg3 Kg8 57.Qh6 Qe1+ 58.Kg2 Qe2+ 0-1
