The Stafford Gambit
In the first game, if the pawn takes our hoarsey, we take it back and now checkmate unstoppably.
In the second game, the other player sees that we are going to checkmate him, so he tries to prevent it with another pawn, but we can still checkmate him, because our queen can easily take this pawn, because the other player cannot take it back, because he is on top of our bishop. Then we can easily checkmate him.
The third variation is "How can we save this game?", and how can we avoid this mate from black when he attacks us with hoarsey and queen. We won't be better than our opponents, but even if we fall behind, we still have a chance to win.
