The Accepted, Main Line is a variation of the Evans Gambit, catalogued as ECO C52. The line runs 1. e4 e5 2. Nf3 Nc6 3. Bc4 Bc5 4. b4 Bxb4 5. c3 Ba5 6. d4, reaching the position shown below after 11 half-moves.
Both sides have pawns in the centre (White on d4 and e4, Black on e5), and one pawn capture is available, so the structure has not settled yet. Development is level at two minor pieces each, and Black is up a pawn of material. It is Black to move after six moves. White’s a-file pawn is isolated.
On the Evans Gambit generally: A romantic gambit sacrificing the b-pawn for rapid development and a strong center. Named after Captain William Evans.
