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.

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.
