Nxh7 Rxh7 ? I assume, in English, you mean 28.Nxh7 Kxh7...? After forcing those two moves, the eval is very favorable, given enough time: Time Depth Score Positions Moves 0:00 1/3 -1.63 1528 29.b5 Kg8 30.bxa6 Nac5 0:00 1/4 -1.63 4914 29.b5 Kg8 30.bxa6 Nac5 0:00 1/4 -1.08 11242 29.g5 Bd8 30.f6 g6 31.Rfd1 0:00 1/5 -1.16 19570 29.g5 Bd8 30.g6+ Kg8 31.gxf7+ Rxf7 32.Qg6 Nf6 0:00 1/6 -0.94 62137 29.g5 Bd8 30.g6+ Kg8 31.Rfd1 Nb2 32.Rxd6 0:00 1/7 -1.04 131777 29.g5 Bd8 30.g6+ Kg8 31.Rfd1 Be7 32.gxf7+ Rxf7 33.Qg6 Nf6 0:02 1/8 -0.47 388471 29.g5 Bd8 30.f6 g6 31.Qg4 Kg8 32.Rfd1 Nb2 33.Rxd6 0:04 1/9 -0.47 785169 29.g5 Bd8 30.f6 g6 31.Qg4 Kg8 32.Rfd1 Nb2 33.Rxd6 0:24 1/10 -0.14 4457893 29.g5 f6 30.gxf6 Bxf6 31.Rfd1 Kh8 32.Nxd6 Rcd8 33.Kh2 Nb2 34.Rd2 Be7 0:54 1/11 -0.12 10488637 29.g5 f6 30.gxf6 Bxf6 31.Rfd1 Kh8 32.Nxd6 Rcd8 33.Qd5 Nb2 34.Rd2 Nb8 35.Bf2 2:57 1/12 0.19 32961624 29.g5 f6 30.g6+ Kg8 31.Nc5 Naxc5 32.Qd5+ Ne6 33.fxe6 Nb8 34.Qf3 Rfe8 35.Qh5 Bd8 36.Qh7+ Kf8 37.Qh8+ Ke7 38.Qxg7+ Kxe6 11:45 1/13 1.11 131179939 29.g5 Kg8 30.f6 Bd8 31.fxg7 Kxg7 32.Qg4 Nb8 33.Nxd6 Qxd6 34.Qxc8 Qg6 35.Qg4 f5 36.gxf6ep+ Rxf6 37.Rcd1 Qxg4+ 38.hxg4 jm
