I watched this speed chess game live and the move blew my mind.
Spoiler
35.Qxg6+!!
Two exclams is a brilliant move. Discovered checks can be nasty and that's true here. The discovered checks of the bishop are devastating.
White's move blew my mind but after I saw that - I could easily see this very simple continuation: check, kill the bishop, check, kill the queen and it's effectively game over.

Daniel Naroditsky is one of the best speed chess players in the world. And he's been on a roll recently.
After seeing this, I wonder how the game would have proceeded if Black had foreseen the move and accepted the rook's loss:
White could still do Qxg4 to take the rook but then the discovered check is averted and Black is free to move
