Learn How to Use an Intermezzo: Mate in 2
This puzzle is a classic middlegame mating net built around an intermezzo, where a forcing check changes the move order and leaves the enemy king with no safe squares. The key idea is that the first move is not the final blow by itself; it is a tactical interruption that drags the king into a worse position. Once the defender is forced to respond, the follow-up is a direct mate supported by the queen and pawn coordination on the kingside.
