1.e4 e5 2.Nf3 Nc6 3.Bb5 f5!? This (I've heard) is one of the sharpest defenses against the Ruy Lopez. I personally don't like the Ruy Lopez. 😠I know this variation goes 4.Nc3 fxe4 5.Nxe4 d5 6.Nxe5 dxe5 7.Nxc6 Qd5! 8.c4 Qd6 9.Qh5+ g6 10.Qe5+ Qxe5 11.Nxe5+ c6 12.Ba4 Bg7 13.d4 exd3 14.Bf4. If white moves 12.Nxc6? is 12...a6! 13.Ba4 Bd7, which will win a piece for black. 😀
Watch the movie "Searching for Bobby Fischer". There Josh play Schliemann against that hustler. One thing that made me laugh was when the hustler asked "whats that?", Josh answered "Schliemann Defence" before he had even played 2.Nc6 😀
