Nooo, I'm a 1.e4 man, always have been and always will be, apart from my odd experiment with 1.b4 or 1.h4.
I generally despise mainline theory though, I learn just enough theory so as to know how to avoid it without getting crushed
As for the 4...f5 line, if the best black can do against what looks an insane gambit is give it back for a slight space/development lead, white should be happy. This position is playable for white, he has ideas to undermine the centre and as Schiller points out, black will have trouble castling, at least short-term.
And well, as for the line which should be talked about on the sicilian forum, it seems a moment of drunken craziness, but it seems extremely difficult to defend. Even 5.Nc3 Bf5 6.Bb5+, playing it as a proper reversed budapest with f4 chucked in, seems decent enough. This forum is giving me a lot of zany ideas for my post-christmas break openings! But I tested out the queen sacrifice in one online game, play continued 6.Bxf7+ Kd7 7.Qxg4 Nxg4 8.Be6+ Kc6 9.Bxg4 e5 10.Nf7 Qf6 11.Nxe5+ Kb6! 12.Nc3 Qd8 13.Nc4+ Kc7 14.Nb5+ Kc6 15.a4 Nd7 16.d4 a6 17.d5+ Kxd5 18.Bxd7 axb5 19.Bxb5 Ke6 20.Be3 Kf7 21.Ne5+ Kf6 22.Nd7+ Kf7 23.O-O-O Qa5 24.Ne5+ Kf6 25.g4 h6 26.h4 Rd8 27.g5+ Ke6 28.Rxd8 Qxd8 29.Be2 Ke6 30.Bg4+ 1-0
I thought at first this was nothing but a bit of whimsy, but I dont think black can get away with 5...Bg4, and after 5...e6 6.Nc3, I seriously like white's position, with ideas of f5 in the air, and seemingly no way to even hold the e4 pawn. Maybe we've just refuted the sicilian?
