Another win with a classic them by Ivanchuk.
Where did white go wrong?
Ivanchuk is a genius!
f5?
I wonder what if Rxh7+ instead.
40. f5 defended the pawn on d4 that was hanging with check.
40. Rh7:+? Kh7: 41. Qh4+ Kg8 42. Qh6 (what else?) Qd4:+ followed by Qf6: – no mating threats left, black is a rook and several pawns up.
