Apparently it is not letting me post an image, I’ve been trying.

Scroll to last move, Qd3#, and back up to White’s pawn move right before the checkmate. It will say a certain knight move was best, so preform the knight move. Then do Qd3+/#, and computers shows up as only a check.


I went to review a game I played and won, and found a similar way to checkmate. But the engine/coach shows it as “d3+ is best”, when it should say “d3# is best”. I looked, and I think it is checkmate. Did I miss a move that made it still a going game?
