Would this make a good best move puzzle?

For which move? I think that around move 18 after the pawns get gobbled there are some good questions to be asked

@MyKindaPotato on move 21 black plays Rc3+ discovered check to win the queen.

@acgusta2 this would make a good puzzle, but if people know beforehand that there is a tactic, it is sort of easy. Good job finding that petite combo!
