Nxc3 Fritz opening book suggest 16...Ne6 17.Bxe6 Rxe6 18.Nxe4 Rxe4 19.Nd4 Ba6 20.b5 Bb7 21.Qf3 Rc8 22.Qg3 Rc4 17.Rxc3 Ne4 18.Bxe4 dxe4 19.Qxd8+ Rxd8 20.Nd4 This knight has a strong and secure outpost at d4. 20...g6 21.Rfc1 White control the c file 21...Kf8 22.a4 h5 23.h4 Rd6? It look's like Mas simply blundering a pawn with this move. Staying put with 23...Red7 Is better 24.Kh2 Bd5 24.Nb5 Rd8 24...Rd2 Give more resistance for e.g 25.Nxa7 Rb2 25.Nxa7 White win a pawn. 25...Ra8 26.Nc8 Re6 27.Rc7 Bd5 28.Na7 28.Rd1 Bb3 29.Rd8+ Kg7 30.Rdd7 28...Kg7 29.Nb5 Re5 Not 29...Rxa4?? 30.Nc3 Rc6 31.Nxa4 30.Nc3 Bb3 31.Ra1 Re6 32.a5 bxa5 33.bxa5 Bc2 34.Rc5 Bd3 35.Nd5 Ra7 36.Nb4 Ba6 37.Rc6 Rxc6 38.Nxc6 Rb7 39.Kh2 Rb2 40.Kg3 Kf6 41.Ra4 Kf5 42.Rd4 Rb1?! 42...Ra2 Placing the rook behind white's passed pawn is better. 43.Nb4! Now black bishop has to leave the blockading a6 square. 43...Bf1 44.a6 Ra1 45.Rd7 Ke6 Not 45...Bxa6?? 46.Rxf7+ Ke5 47.Ra7 and black will lose his bishop. 46.Rb7 f6 47.a7 Kd6 48.Nc2 Better is 48.Rb6+! Kc5 (48...Kc7 49.Nd5+) 49.Ra6 Bxa6 50.a8Q 48...Ra5 49.Rb6+ Ke7 50.Nd4 50.Nb4! Threatening Ra6 or Na6 50...Rxa7? 51.Nc6+ 50...Ra2? The last mistake. A little stubborn is 50...Kd7 51.Rxf6 Kc7 51.Rb8 1-0

Mas resign because after 51...Rxa7 52.Nc6+
