Main Line (3...Nf6)
1.e4 e5 2.Nf3 Nc6 3.c3 3...Nf6 4.d4 Nxe4

Black grabs the e4 pawn. After 5.d5 Ne7 (Ne5 is also playable) 6.Nxe5, White has active piece play for the pawn.
A arma surpresa a 1.e4 e5: pouca teoria, estrutura d4 rápida, desestabiliza adversários mal preparados.
1.e4 e5 2.Nf3 Nc6 3.c3

A Abertura Ponziani (1.e4 e5 2.Cf3 Cc6 3.c3) prepara imediatamente d4 para construir um centro ideal. Pouco jogada ao mais alto nível por causa de 3...d5!, o lance de igualização, continua a ser uma arma surpresa eficaz ao nível de clube onde poucas pretas conhecem esta resposta precisa. As pretas que tentam 3...Cf6 deparam-se com 4.d4 e um centro branco esmagador. Carga teórica mínima (20-30 variantes), ideal para um jogador de 1.e4 que queira evitar a teoria pesada da Espanhola e da Italiana.

1.e4 e5 2.Nf3 Nc6 3.c3 3...Nf6 4.d4 Nxe4

Black grabs the e4 pawn. After 5.d5 Ne7 (Ne5 is also playable) 6.Nxe5, White has active piece play for the pawn.
1.e4 e5 2.Nf3 Nc6 3.c3 3...d5

Black's main equalizing try, sometimes called the Jaenisch Counter-Attack. After 4.Qa4 dxe4 5.Nxe5 Qd5 6.Nxc6 Qxc6 7.Qxc6+ bxc6, a balanced endgame arises. (The true Ponziani Counter-Gambit is the sharper 3...f5.)
The Ponziani is an excellent surprise weapon at club level. Study the main 3...Nf6 4.d4 line and you'll win many games on preparation alone.
Add the Counter-Gambit lines (3...d5). The sharp tactical play rewards calculation skills.
Use the Ponziani as a rapid/blitz weapon. In classical games, prefer the Italian Game or Ruy Lopez for deeper strategic battles.
At club level: surprisingly strong. At the top level: rarely played because theory favors Black slightly. As a surprise weapon, it scores well because most opponents have no preparation.
3...Nf6 (main line) or 3...d5 (Counter-Gambit) are both good. 3...d5 is the most ambitious, immediately challenging White's center. Avoid 3...Bc5 which allows a quick d4 with tempo.
The Italian Game plays 3.Bc4 (developing the bishop first). The Ponziani plays 3.c3 (preparing d4 directly). Both want a big center with d4, but the Ponziani is more committal and rarer.
Rarely at the top level. At club level it's a favorite of surprise-weapon players who want to avoid mainline theory. Low theory load, high practical value.
Yes, it's one of the easiest openings to learn for White. Simple plans (c3, d4, develop pieces), few forcing lines, and most opponents won't know what to do.
