Aggressive Chess Gambits – The Wing Gambit
This gambit can be used against both the Sicilian and the French Defenses. In both cases, White sacrifices his b-pawn to occupy the center and develop faster.
And it is a very dangerous weapon, especially if Black doesn’t know some precise theory. In the Sicilian it starts with 1.e4 c5 2.b4 immediately:
In the case of 2…cxb4 White usually continues with 3.a3, and then develops quickly with d2-d4, Bf1-d3, and then starts an attack.
In the French Defense, White should wait for …c7-c5 first. After 1.e4 e6 2.Nf3 d5 3.e5 if Black plays 3…c5, then White meets it with 4.b4.
Again, after Black accepts the gambit (4…cxb4), White continues with 5.a3, and then d2-d4, Bf1-d3 with a strong center and a potential attack on the kingside.
