Difficult pawn calculation
21... Rc8xc1 22. Be3xc1 Ke8d7 23. Bc1d2 Rh8c8 24. Rb3c3 Rc8xc3 25. Bd2xc3 Kd7c6 26. Na3c2 d5
? Here, both sides calculated the same line but with different results... as it turns out, we were both wrong!
27. Bc3xe5
The idea was the pawn would eat its way to c2 and both Kings would be bound to that spot, resulting in a "who gets Zugzwanged" battle
27... dxe4 28. Be5xf6 exd3 29. Bf6xe7 dxc2 30. Be7g5 Kc6d5
Both sides had calculated Black King to b1 and White King to d2, leaving just the pawns to play
31. Bg5c1
However Kf1 first here, then Bd2 instead of c1 was considered better
31... Kd5c4 32. a3 Kc4b3 33. Kg1f1 Kb3a2 34. Kf1e2 Ka2b1 35. Ke2d2
So now the critical position... we both wanted this, but who is better?
35... h6
? What surprised me was that g7-g5 here for Black was actually the winning move, as Fritz evaluated the position at -5.07
36. g3
Black is still winning however, with move h6-h5 this time
36... g6
? Incredible, this swings the evaluation completely the other way, now White is winning
37. h4
(I really wish I was at a level where I could calculate these sort of lines with accuracy)
37... h5 38. f3 f6 39. g4
There are multiple ways this could go, all lead to Black's zugzwang and eventual mate in the corner
