How to deal with the Sicilian Wing Gambit? The Sicilian Wing Gambit is never popular with good players, thus, it is only played as a surprise. But, how to deal with this unexpected surprise? It seems to me that all responses would just worsen Black's position. What to do if I face it?

[White "Wing"]
[Black "Gambit"]
[fen ""]

1.e4 c5 2.b4
The easy way out is to just play 2…b6. This move certainly doesn't "just worsen" blacks position:


Now both players can fiancetto the bishop, but a black bishop on b7 actually has a target, the e4-pawn.
If white plays 3.bc bc the b-line is open. This makes the option of 0-0-0 quite unattractive, an option that is much more often utilised by white, especially in the sicilian.
If white doesn't take on c5, he will sooner or later have to deal with the threat against b4. Actually, he will have to evaluate the threat against b4 every move!
