Sometimes it’s hard to know how to phrase things in here. I want the Goldilocks Zone. Not to obvious but surely not annoyingly difficult either.
How are these?
Hint: You'll probably want to peek at this.
It’s a “!” move. It took Magnus ~3 seconds to find it. It’s not crushing or anything. But it is hard to see.
Big hint
Poisoned pawn.
Answer
34.Rd3! It sets a trap. Even GMs can fall into a trap in speed chess.
34…Qxe4 is an a terrible move that means white gets black’s queen for the cost of a pawn and a rook.
35.Rf3+. It’s a discovered attack on black’s queen by white’s queen.

I know nothing about chess but I’d have said move the castle one right to put the king in check, then drive the pawns up to pressure it, or move the castle 1 left and pick off work through the two bishops.
