Damiano Defense: Refutation to 2...f6
Main line: 1.e4 e5 2.Nf3 f6 3.Nxe5 Qe7 4.Nf3 Qxe4+ 5.Be2
Opening moves: 1. e4 e5 2. Nf3 f6. Black tries to over-defend the e5 pawn but badly weakens their king. White can punish this with a simple tactical idea.
In this short 1...e5 theory line, you will see why the Damiano Defense is considered a bad opening. White sacrifices on e5, brings pieces out with tempo, and chases Black's queen while the king stays in the center.
