THE EVANS GAMBIT

Board Position
A major variant of the Giuoco Piano. White's attack is accelerated by playing a 4.P-QKt4(b4) gambit (move 4w, left) invented by Capt. W.D. Evans in 1824. Board Position
Black usually accepts the gambit and then, with careful play, has little to fear after move 7wb (right). White's compensations for the pawn sacrifice are a strong centre, quick developing and good attacking chances. The refutation (as so often with gambits) is to give the pawn back at a convenient moment.
Popular lines include the Normal Position (a branch of the main below), the Cordel Var. (below), the Alapin Var., the Richardson Attack, the Compromised Defence and the Evans Gambit Declined.
