Nh7+ Ke7 7. Bg5+ [D] r1b1r1nQ/pp1pkppN/8/q2P2B1/1b6/8/PP3PPP/R4RK1 b - - 0 7 Which is completey forced, but i suspect that chess programs will be having trouble finding Bg5+ down the line when given the position before Bxh7+. After Bg5+ black can only play Kd6 [D] r1b1r1nQ/pp1p1ppN/3k4/q2P2B1/1b6/8/PP3PPP/R4RK1 w - - 0 8 (after f6?? Qxg7+ but black is already lost here so not much difference.) [D] r1b1r1n1/pp1pk1QN/5p2/q2P2B1/1b6/8/PP3PPP/R4RK1 b - - 0 8 so Kd6 Qxg7 Re2 Bf4+ [D] r1b3n1/pp1p1pQN/3k4/q2P4/1b3B2/8/PP2rPPP/R4RK1 b - - 0 9 or Kd6 Qxg7 Kc7 Rac1+ [D] r1b1r1n1/ppkp1pQN/8/q2P2B1/1b6/8/PP3PPP/2R2RK1 b - - 0 9 or Kc7 Qxf7 or K c7 Bf4+ even, but it is all over here. How did the game proceed?
