In the diagram position White could have won with the immediate 21.Bxh7+!, while the game continuation 21.f4 Ng4 22.Bxh7+ Kxh7 22.Qxf8 was nicely refuted by Black. Two queens in enemy territory - enjoy!
"Check all checks and captures" is a useful tip when accessing sharp positions, however, in the diagram White uncorked a bomb move of a completely different kind. I'm curious to see if you can find it!
