||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.
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.
