      • In chess, the Wing Gambit is an opening in which White plays an early b4, deflecting an enemy pawn or bishop from c5 so as to regain control of d4, an important central square. (Or in which Black plays ...b5, but Wing Gambits offered by Black are very rare.)
      The most common Wing Gambit is in the Sicilian Defence (1.e4 c5 2.b4). The most important Wing Gambit is the Evans Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.b4), treated separately.


      Against the Sicilian Defence


      The Wing Gambit in the Sicilian Defence runs 1.e4 c5 2.b4 (diagram). After Black takes with 2...cxb4, the usual continuation is 3.a3 bxa3 (3...d5! is more recently considered superior, when White must avoid 4.exd5 Qxd5 5.axb4?? Qe5+ winning the rook, a blunder actually seen in tournament play in Shirazi–Peters, Berkeley 1984; instead 5.Nf3 is better) and now the main line is 4.Nxa3, though 4.Bxa3 and 4.d4 are also seen. It is also possible to decline (or at least delay acceptance of) the gambit with 2...d5.
      For his pawn, White gets quicker development and a central advantage, but it is not generally considered one of White's better choices against the Sicilian and it is virtually never seen at the professional level. Amongst amateurs it is more common, though still not so popular as other systems.
      After Black's 2...cxb4, another popular third move alternative for White is 3.d4. GMs George Koltanowski, David Bronstein and World Champion Alexander Alekhine have played this line.
      White can postpone the gambit one move by playing the Wing Gambit Deferred, playing 2.Nf3 followed by 3.b4. The deferred Wing Gambit is considered to be best when black responds 2...e6. The Portsmouth Gambit runs 2.Nf3 Nc6 3.b4, where Black is disinclined to refuse the gambit due to the positional threat 4.b5, displacing the knight and disrupting Black's smooth development.
      It is also possible to prepare the gambit by playing 2.a3!? followed by 3.b4.


      Against the French defense


      The Wing Gambit can also be played against the French defense, although this is largely refuted at a grandmaster level. One line, as popularised by Gotham Chess, goes 1.e4 e6 2.Nf3 d5 3.e5 c5 4.b4, and black often takes cxb4 followed by a3 with a further gambit of a pawn in exchange for quick development of the minor pieces, and/or d4 and c3 to solidify the center.
      Black usually plays Nf6 at some point, and White often chooses to play agressively on the kingside, with the option of not castling and keeping the rook on the h-file to support the pawn storm.


      In other openings


      A related idea is found in the Caro-Kann Defence after 1.e4 c6 2.Ne2 d5 3.e5 c5 4.b4, however Black can immediately achieve an advantage by playing 4...d4! (this move is also strong in the second French line given above). Even rarer is the Wing Gambit in the Bishop's Opening, 1.e4 e5 2.Bc4 Bc5 3.b4, which has some resemblance to the Evans Gambit.
      There are several other "Wing Gambits" in various openings, but they are very rare, and not as notable as the openings mentioned above:

      In the English Opening: 1.c4 c5 2.b4, or 1.c4 b5 (The Jaenisch Gambit)
      In the Marshall Gambit of the Scandinavian Defence: 1.e4 d5 2.exd5 Nf6 3.d4 g6 4.c4 b5
      In the Ware Opening: 1.a4 b5 2.axb5 Bb7
