Perhaps the curse of being such a good calculator is that you can "calculate your way out of" anything, occasionally missing simple defensive resources in the process. } (43... Bg7 44. Nf4 Qd7) 44.

Qc6 Be7 46. h6 { Suddenly, White has tightened the net. There were several subtle moments here that could be easy to overlook when calculating these variations. But why allow the knight to f6? The pawn to h6? The king to get stuck on h8? None of this was forced. } 46... Bf8 47. Nd7! Bxh6 48. Qc8+ { with mate to follow in two moves. } 1-0
