If you play it
Offbeat openings trade theory for the burden of working everything out at the board. There is no book to fall back on, so every plan has to come from reading the structure — which is hard, and is why the accuracy drops.

White's score with the Ponziani Opening, by rating

In line with White's average at this level (51.8%). 184 games by 83 players · 4.9% draws

The marker on each bar is White's average score across all openings at that rating and time control. We only call an opening above or below that average when the gap is far beyond the margin (±) — about 1.7 times it — because we compare dozens of openings at once, and chance alone would make a few of them look special.
The typical mistake
If you face it
You are being taken out of theory on purpose, and it is working. The reply is almost always the boring one: take the centre, develop, castle. Trying to punish a sideline immediately is exactly how the surprise pays off.

How these numbers are made
Every week we draw about 1,008 Chess.com players at random from the public player lists of twelve countries, never one already drawn in the previous weeks, and read their rated games from the last complete month. These numbers add up the latest 2 weekly samples: 2,016 players, 1,382 of whom played in September 2026. A game counts once even if both players are in the sample, and no single player can add more than 10 games to the same opening and time control, so one enthusiast cannot tilt the numbers. Rating bands use the average rating of the two players in that time control, because ratings are not comparable between blitz and rapid. Bands with fewer than 40 games or 10 players are shown but not judged. The score counts a draw as half a point. The ± is a 95% margin, but a gap is only judged beyond 3.3 standard errors: with many openings compared at once, a looser line would flag openings by pure chance. Players on this site are never part of the sample.
