Description
The Ponziani Opening (1.e4 e5 2.Nf3 Nc6 3.c3) is an old open game in which White prepares d4 with a pawn, as in the Giuoco Piano, but before developing the king's bishop. It is named after Domenico Lorenzo Ponziani, who analysed it in 1769.
Origins
The opening is much older than Ponziani: it was already discussed by 1497, by Lucena and in the Göttingen manuscript. It has also been called the English Knight's Game, and Staunton's Opening after Howard Staunton, generally considered the world's strongest player from 1843 to 1851. Frank Marshall wrote in 1904 that "there is no point in White's third move unless Black plays badly". Magnus Carlsen won with it in 2013.
The idea
3.c3 prepares d4 so that White can take back with a pawn and build a centre. Sometimes White also uses the queen on a4 or the bishop on b5. The drawback is that c3 takes the natural square from White's queen's knight, and the e4-pawn is unprotected for a moment, so Black's best replies counterattack in the centre at once.
Main lines
- Jaenisch Counterattack 3...Nf6: Black attacks e4. After 4.d4 Black can take on e4 or on d4; 4.Bc4 is the Neumann Gambit.
- 3...d5: a direct strike in the centre, usually met by 4.Qa4, with the Steinitz Variation 4...f6 and the Caro Gambit 4...Bd7; 4.Bb5 is the Spanish Variation.
- Ponziani Countergambit 3...f5: a sharp counter-gambit.
- Romanishin Variation 3...Be7: a passive reply, usually met by 4.d4.
Strengths and weaknesses
Strengths
- A surprise weapon: few opponents know the theory well.
- Sharp and dynamic play in several lines.
- The same c3 and d4 plan as in the Italian, with different move orders.
Weaknesses
- Considered inferior to other third moves such as the Ruy Lopez.
- Black equalises easily with an early ...d5 or ...Nf6.
- White's queen's knight loses its best square.
Who should play it
The Ponziani suits players who want an offbeat open game and like sharp positions, and is mainly used as a surprise weapon. It is less suitable against opponents who know the 3...Nf6 and 3...d5 lines.
The numbers
On Lichess the results hardly change with rating: White wins 48.2–50.3% and Black 45.2–46.4%, and draws grow from 3.8% below 1800 to 6.5% from 2200 up. There are only about 1,600 master games, too few to draw firm conclusions.
