What a fool I am! I exchanged my queen for two coordinated rooks. Nothing wrong with that if you look at the position on the left. I figured that with an outside passed pawn that can be easily defended and sheperded by my rooks, I can win this game. So, I continued with 40. h4. This game actually ended in a draw after black went on perpetually checking my king after several moves. I won't show how that went, but I can tell you that I missed 40. Rb7+, Qb7 41. Rb7+, Kb7 42. h4 and winning. You see some, you miss some.
