Bishop's Opening: Berlin Defence, Greco Gambit
4...Qh4+!
Black punishes White's careless 4. fxe5?? and will now either win material or checkmate the White king. White has three legal moves: 5. Kf1?? gets checkmated immediately to 5...Qf2#, 5. Ke2? leads to a long forced checkmate sequence after 5...Qf2+ 6. Kd3 Nc5+, and 5. g3 is the only non-losing move, but it will still lose a rook after 5...Nxg3 6. Nf3 Qe4+.
