If you’re unfamiliar with algebraic chess notation, check out the wikiHow article to brush up. As well as freeing your queen, you need your opponent to expose their king. If Black then moves their bishop pawn 2 spaces to f5 to tempt White, the checkmate in three moves is on!
This isn’t a smart move from your opponent, but maybe you can lull them into it. The idea of this move is to make sure nothing can block off your route to your opponent’s king after you make your next move.
You really need your opponent to play into your hands to pull off this three-move checkmate.
You are trying to tempt your opponent to move their bishop and knight pawns. You need your opponent to respond by bringing out their bishop pawn one square to f6. It can also work if they move their knight pawn forward two squares on this turn, as long as they move the bishop pawn on their next move.
In order to clear the way to your opponent’s king, you need them to move their knight pawn ahead two spaces to g5.
Again, this looks simple and it is. So, don’t expect it to work very often! In theory, there are loads of variations on this. The key moves are getting your queen to h5, and your opponent’s bishop and knight pawns out of the way of their king.
