This move gave white a strong post on the e5 for his knight. 35.Nxc4 dxc4 36.Ne5+ Rxe5 37.dxe5 Rd3 38.hxg5 38.Rd2! Exchanging white rook is simpler. 38... Nd5 (if 38...Rxc3 39.Rd7! then 39... Ne6?? or 39...Ne8?? both will be checkmate with 40.h5#) 39.Rxd3 cxd3 40.Bd2 38...hxg5 39.Bd2 Bg7 40.Re1 Kf7 41.Bxg5 Rxc3 42.Bd8 Fritz suggest the brilliant 42.e6+! Nxe6 43.Bh4 threatening Rxa6 42...Ne6 43.Rxa6 Rd3 44.Bf6 Bf8 45.Ra7+ Kg6 46.Rea1 c3 47.Be7 c2 48.Rc1 defending against the passed c pawn from behind with 48.Bxf8! Nxf8 49.R1a6+ Kh5 and then white place his rook behind the c2 pawn 50.Rc6 is better 48...Bxe7 49.Rxe7 Nd4 50.Rd7? once again placing his rook behind the passed pawn is correct 50.Rc7 50...f4? Black should try for a draw with 50...Nb3 51.Rd6+ ( not 51.Rxd3? Nxc1 52. Rc3 Nd3 53.Rxc2 Ne1 +) 51... Rxd6 52.exd6 Nxc1 53.d7 Nb3 54.d8Q c1Q 55.Qg8+ Kf6 56.Qxb3 Qd2 57.Kf1 Qd4 58.Qb1 Qc4+ 59.Kg1 Qc3 60.Kg2 Kg5 61.Kh3 Kf6 62.Kh2 Qd2 63.Qa1+ Kg6 64.Qa6+ Kg5 51.Rxc2??

Mas succumb at the very last moment. Winning is 51.Rd6+! Kf5 52.e6 Ne2 (52...f3+ 53.Kh2 Rd2 54.e7 Rxf2+ 55.Kh3 Re2 56.Rxd4) 53.Rxd3 Nxc1 54.Rc3 51...Nxc2 52.Rb7 52.Rxd3?? Ne1+ 53.Kh3 Nxd3 52...fxg3 53.fxg3 Na3 0–1 What a pity. Mas was very close to winning against Ganguly .
