good opening for white against the sicilian


It doesn't look like you have done badly versus the Sicilian.
According to your Insights, you have played against it 11 times and have a 63.6% win rate against the open Sicilian.
You have played 7 times versus the closed Sicilian with a 71.4% win rate.
Both are pretty good.
Maybe you have another account.

Apart from the obvious answer which is the Open sicilian, I believe there are a lot of interesting sidelines to try off.
Against 1.e4 c5 2.Nf3 Nc6, the obvious one would be the Rossolimo with 3.Bb5, which nowadays it could be said it has the same quality as an open sicilian.
Against 1.e4 c5 2.Nf3 d6, probably the Canal/Moscow with 3.Bb5+ is a simple and easy solution against it.
Against 1.e4 c5 2.Nf3 e6, it's a bit more tricky, but you can explore 3.g3 in the case you are interested in a King's Indian attack transposition, or either 3.b3 , which is a bit wacky but interesting sideline for white.
Other than that, you can always explore stuff like the Grand Prix attack with 1.e4 c5 2.Nc3 Nc6 3.f4 or the Tiviakov (Rossolimo-Grand Prix) stuff with 1.e4 c5 2.Nc3 Nc6 3.Bb5, both are relatively simple and practical weapons, specially for low time controls as online rapid and blitz.

No. The King's Indian Attack is an excellent option, but NOT with that move-order.
The proper way to enter the King's Indian Attack against EITHER the 2. ... e6 Sicilian or against the French Defense (that's 1. ... e6) is to immediately play d3 so that you can reply to Black's ... d5 move with Nbd2! preventing an exchange of Queens.
The line that you suggest loses all of White's opening advantage right in the early opening.

i have done well with the closed sicilian (the early be3-qd2 lines) and been beginning to dabble with the nc3 grand prix (the line with early qe1 ideas)although theoretically both should give black an easier equality. but one line which i think is underrated is open sicilians with early g3. Like the closed sicilian, they tend to be more positional but unlike it, black usually doesnt get a massive queenside expansion. I find that if black is not prepared for it,he can get in easy positional trouble at not much risk for white, but even if he successfully navigates the opening, he wont get any real attack going if white knows how to neutralize the queenside play.
There is this at first weird maneuvering in some of these lines where you first go a4 (To stop b5) and then play ra2!? which at first seems bizarre, but it has two purposes, one is to better play b3 which both supports c2-c4 (usually after the knight on c3 has gone to d5) and to potentially support bb2. But the other purpose is that since the queen rook in the sicilian often goes to c8, ra2 protects c2 after b3.

Not true. 3.g3 is perfectly OK after 2...e6.
White should answer an eventual ...d5 with exd5 plus d4 which is a typical potential IQP case.
