How do you play against the Sicilian Defense?

"... There is no doubt in my mind that if you really want to test the Sicilian then you have to play the main lines of the Open Sicilian. The problem is that there are just so many of them ... and keeping up with developments in all of them is a substantial task. ... as you become older, with other demands on your time (family, job, etc.) then it becomes more and more difficult to keep up with everything. At this stage it may make sense to reduce your theoretical overhead by adopting one of the 'lesser' lines against the Sicilian: 2 c3, or the Closed Sicilian, or lines with Bb5. ..." - GM John Nunn in part of a 2005 book where he discussed a 1994 game in which he had played 2 c3.
A 700 rating is supposed to buy 30 books on the Sicilian, specializing in 30 move openings?
Stick to the basics like B50...1 e4 c5 2 nf3 d6 3 c3 Nf6 Bd3(going to c2 and then white plays d4)
if 2...e6 or nc6 then 3 nc3....for example 2...e6 3 Nc3 Nc6 4 h3 d5 5 Bb5 d4 6 bxc6 bxc6 7 ne2
Example: game is over by 30 moves....and black has to restudy in case someone surprises again
Hello, guys. What if you play 1. e4 1. c5 2. d4 2. cxd4 3. Qxd4?
Nc6.
I meant if it was a good move or not but thanks for telling me the continuation.

Here is how an IM played white against my Sicilian. Note that he "went out of book" pretty early. Of course I ended up losing but I held my own for quite awhile. I did not get crushed and in fact, the post game analysis showed that my opponent made the first inaccuracy not me. All in all, I'm very happy with my game an he even said I played well. Carry on!

Well,
He asked how to play against the Sicilian. Here is an example of how an IM played against it. Always expect your opponent to play well no matter what your opening is.

I've been playing the 2 c3 (Alapin) Sicilian. According the chess.com's Opening Explorer, my results are so-so but a lot of the games were against 1800+ players. I'm 3 wins, 2 losses and 1 draw at chess,com, the draw coming in the past month against a very strong Bulgarian player I faced on Board #1 for Team USA in an 1800 & Under match where my opponent had recently dropped a lot in rating.
I play it because I haven't memorized a lot of standard variations of the Sicilian and Black has his choice of variations after the standard 1 e4 c5 2 Nf3 d6 3 d4 cxd4 4 Nxd4 where White's d4-N will have to make another move and Black has 2 center Pawns to 1 for White.

Play a (universal) reversed black defense from the white side. Very simple. Saves lot of study time too. Larsen's Attack (i.e. a reversed QID) comes to mind. But the list is fairly long. If you want to go for BIG Theory play the KIA. For Little theory (but still fairly big) play a reversed Schlechter Grunfeld.
And there are still more choices for reversed systems, naturally.
I agree.
A "simplistic" advice that is actually much better and much deeper than it looks.
Indeed, an even more reduced version of this thumbnail advice is --
Play for a Draw, until you get into the endgame. Then play for win, only if you should.
GM Pal Benko did it on a regular basis, to deadly effect.
Me personally, opposite-side castling and all out attacks (ala english attack, yugoslav, richter-rauzer, keres attack and the like); to a degree though this is what the sicilian player probably wants. My recommendation: find a respectable side-line you like, figure out how to get out of the opening, and focus your practice on everything else. Although in an open-sicilian the stronger tactician should probably win; so alternatively, play Nf3 and d4 and brush up your killer instinct with tactics practice.
There are lots of lines with Be3, Qd2, and f3. All pretty theoretical and sharp, but if you're wanting a play this against almost anything set-up it might be viable (the sveshnikov will ruin your day now though.)
As a sicilian player I find that Bb5 takes out quite a bit of fun, so those lines might not be bad if you want to just get to the game and don't mind a quieter game.
