Checkmate or Queen capture?


Whats the best decesion here? to capture the pawn and checkmate for a win or taking advantage and and taking out the queen?.feel free to tell me what you think.

For practical purposes, if you can see the mate, then play the mate. If you can't calculate it to mate, then take the queen and finish him off later.
For training purposes, it's nice when a computer shows you a mate you missed. Going over it can help you learn a new pattern of attack. But if you took the queen without seeing the mate, you shouldn't feel bad because it's a completely winning move.
But again it's good to know of the mate because in a future game there may be no queen to take, and a similar mate may be the only good move you have.
