At the GM level I believe the alapin sicilian is the most popular anti-sicilian.
Anti-Sicilians

Yes. the alapine looks interesting. Through abit of logic for inexperienced players I think that the Alapine is a bit more positional, as it can lead to knight and bishop development problems

I play the Alapin.
As far as I know, the Bb5(+) systems are also very popular at GM level (besides the Open, of course).
And then there's Zviaginsev's 2.Na3!? :-)

For practical purposes 2 c3 is a better anti-sicilian because the Bb5(+) lines cant be played against 2...e6 or 2...a6 ( OKelly) sicilians.

I do not think the Wing's Gambit is sound enough, as IM Andrew Martin pointed out in one of his recent articles, 3...d5 gives black full equality. Nevertheless, you might find enough fire in 2.b4 in club level matches!
I think I have read somewhere that in the Alapins, should black choose to take the pawn (for example, 1.e4 c5 2.c3 g6 2.d4 cxd4, with black intending to strike back in the centre with d5), instead of white taking back with the pawn, some masters have tried Qxd4!? instead.

I really like the Closed Sicilian because theory is not an huge portion of understanding the opening. Knowing the ideas and how they relate to one another can turn the game in your favor

Yes. the basic winning idea for White when playing the Wing gambit is.
yes! and thats how the 2.b4 bites if black doesnt know the theory (very often in clubs!) and does not play the 2...cxb4 and 3...d5!
There is also 1.e4 c5 2.a3!? which has quite a large book written about it. I blieve it's great because it is possibly the most unknown of the anti sicilians.

I think that the e pawn will stop d5. for example.
sry, i meant 1.e4 c5 2.b4 cxb4 3.a3 d5

ok thanks. I do notice that against inexperienced players it can come as an absolute surprise. my friends are Sicilian players and I see the shock horror on their face when instead of my usual 2. f4. I play Wing gambit. I wrote an article on the psychology of gambits. interesting (i hope)
Although Wing Gambit is quite dubious
I play the Alapine as it takes all the book out of those dragon or Najdorf players.
White allows an isolated D pawn for well placed bishops as well as well posted knights and an open C file to play in.
1 e4 c5.
The Sicilian Defense, statistically one of the best openings for black. It appears in 1/6 of Grandmaster games. There are many ways of playing the scenario. Most common are. 2. Nf3 (often goes along classical lines and the dragon) 2. d4 (morra-smith) 2. Nc3 (Closed, but often goes to a Grand Prix Attack). 2. c3 (Alapine)
And one of my old favourites, very agressive. 2. f4 (Grand Prix attack, often comes from closed). Those are the main anti-Sicilians, recently though, i have found an almost unknown alternative: 2.b4. The Wing gambit. Maybe it is my mania for trading c pawns for d pawns, and b pawns for c pawns, or extinguishing the opposition's central command, but I like the look of it.
I started this topic to see what the general audience uses as an anti-Sicilian
