Greco–, 1619: 1. e4 b6 2. d4 Bb7 3. Bd3 f5? Bauer calls this move "simply suicidal". Black gravely weakens his kingside in an attempt to gain , but White can win by falling into Black's "trap". Normal is 3...e6 or 3...Nf6. Also possible is 3...g6 ("" – Andrew Martin) heading for a Hippopotamus Defence, when Martin considers 4.f4 f5! (as in the game Serpik–Blatny, U.S. Open 2003) strong for Black. 4. exf5! Bxg2 5. Qh5+ g6 6. fxg6 (diagram) Nf6 7. gxh7+ Nxh5 8. Bg6# 1–0
