Italian Game, Rousseau Gambit
Chess opening From Wikipedia, the free encyclopedia

The Rousseau Gambit (or Ponziani Countergambit after Domenico Lorenzo Ponziani) is a chess opening that begins with the moves:
The gambit is named after French chess master Eugène Rousseau. White can decline the gambit by supporting the e-pawn with 4.d3. The resulting position is similar to a King's Gambit Declined with colours reversed, and White's king bishop aiming at Black's weakened kingside. Black will have trouble castling kingside, and Ng5 is a likely threat. White's position is better, but still requires careful play.
Key themes for White are to attack Black's kingside and to avoid attempts by Black to simplify the position. Exchanges involving White's light-square bishop are particularly suspect.

White responses
Gambit Declined: 4.d3
White can decline the gambit and wait to capture the f-pawn. 4...Bc5 transposes to the Lucchini Gambit.
Gambit Accepted: 4.exf5
White still has a good game after the inferior 4.exf5, but the position is less clear. Black usually plays 4...e4, which White may meet by 5.Nd4! Nf6 (5...Nxd4? leads to trouble after 6.Qh5+) 6.Nxc6.
4.d4!
