Early Bc4 stuff: the bane of all sicilian players. Everybody is convinced it loses by force, but it just doesn't. White players can adopt this just to mess with you.
It certainly does not lose by force. I don't think I have ever seen a GM play this. Club players play it because they want to avoid the theory. Often they just want to develop their pieces w/o any real plan. I very rarely have any trouble in the opening here.
And it can be more common than the open sicilain at club level.
A long time ago I was a friend of a Yugoslav GM who was a student in an English University just before England got it's first GM. We went up to play in a top open tournament in Edinburgh where noone knew him. He got to play 4 rounds as black against present and past chess champions of Great Britain. Every game was the same. I'd look in and black seemed to be doing fine. I'd look in later and white had sacked a piece with questionable (to me) compensation. I'd look in later and he'd sacked another piece and I could not see a concrete win. Shortly therafter black resigned. It was like watching Tal at his finest. Of course, nowadays black players know the lines better than back then, but the point is that I've seen a GM player play early Bc4 lines against weaker but still respectable players and win quite easily.
well i played one rapid game. My opponent was black. It was very funny...
