As the others have said, provided that it's fundamentally sound, any line is good if you understand it better than your opponent! However, I've had good results against the Sicilian by setting up the Maróczy Bind and recommend it.

Eh, I wouldn't base it on your statistics either. That is to say, you shouldn't play an opening if you only ever lose with it obviously, but ignore statistics otherwise. Try some good lines out, if you like the positions you're getting, stick with it, if not, then move on to something else! It helps to play over a few master games with the opening (wins, draws and losses) to see what your themes are.

I know, just thought I'd mention it anyway.

On occasion, I make use of the Maróczy bind in the 2. ... d6 3. d4 cxd4 4. Qxd4 line I play. Though, I usually end up playing for c5 which is a different.
The disadvantage of the Closed, GPA and various Maróczy bind setups is the positional nature of the position. In my opinion, below-average players do well to avoid that.
That said, most Maróczy bind formations come from 3. d4 cxd4 4. Nxd4, which is something most below-expert players should probably avoid...

Thanks for all your guys' help! I think I'll just stick with the Alapin. Oh yeah, and also I have another question. I know I should also know the ideas behind the openings as well in case the opponent goes off the book line. So are there websites or books that'll explain to me the ideas behind each opening? (they don't really do that in Nunn's Chess Openings) Thanks once again.

The best web guide I know of to the ideas behind the various openings is Dr. Dave's at the Exeter Chess Club. Of course, he doesn't cover every opening and every line of every opening, but he gives good overviews of the main ones. There's also a lot of other great info on that page.

Hope that helps.

Certainly a helpful page, I used it quite a few years ago.

You can't play the Maroczy Bind if Black doesn't play g6, but Nf6 attacking the e pawn which you have to protect with Nc3. (after that the c-Pawn is locked)

I recommend the Grand Prix Attack, which can be deadly for Black if he doesn't know it. (You don't have to play d4, don't worry) Study it here: The Grand Prix Attack

opening principles, depending on your level read Mastering the Opening by John Watson it great information on just that kind of thing.

The Alapin is pretty theoretical in itself. You'll just reduce the number of lines you'll have to learn, but you will still have to keep up to date. And some of the lines are very sharp.

From the black side of the Sicilian, I can say that the move I loathe the most is the Bb5 lines, either in d6 or Nc6 variations. In the d6 line, it's almost like an improved version of the Maroczy, and in the Nc6 line, you have to squirm for a pretty long time before you can claim equality. Generally, Bb5 is less tactical and more positional.

There are a lot of lines in the Alapin, but not as many choices for black. Black's probably going to play either 2...d5 or 2...Nf6. Anything else would be a transposition out of Sicilian territory. White can basically choose one pet line against each response and concentrate on those. Against the Open Sicilian, you need a line against tons of different variations of open Sicilian.
