Performance Across Rating Levels

White's edge erodes by 3.5pp from 1200 to 2500 Elo, suggesting Black's counterplay is easier to find with experience.
Time Control Patterns
Time control matters here: blitz players reach for this opening more than others. In bullet, it appears in 0.02% of games (544,379); White wins 50%. Blitz shows 0.03% adoption across 1,252,677 games, White scoring 50.5%. In rapid, the share rises to 0.02% — 187,699 games, White 52.5%. White's score swings 2.5pp across formats, so time control isn't just a stylistic choice here — it shifts the actual results.
Move Diversity and Theory Depth
Looking at move selection shows how forcing — or not — the position really is. At 1200 Elo, the top reply is Nf6, played 38.7% of the time. There are 6 other moves seeing meaningful share, and 72.6% of games stick to established theory. Entropy: 2.58. By 2500, Nf6 dominates at 72.8% of replies; only 3 viable alternatives remain and 97.7% of moves are theory. Entropy drops to 1.26. That entropy collapse is the signature of a line where preparation pays off: at the top, players know the best move and play it.

Common Mistakes
- Drifting away from main theory — At 400 Elo, theory adherence sits at 74.2% — versus 90.4% at 2000. The most popular deviation is e5 (played 17.9% of the time at 400, much less so up top). It looks fine but quietly hands the better-prepared side an edge.
- Neglecting development — It can feel productive to make extra pawn moves early, but falling behind in piece development is what loses most amateur games — especially in open positions where active pieces find squares fast.
- Ignoring the kingside attack — In sharp Sicilian lines, White typically castles long and pushes the h-pawn. Without your own counterplay on the queenside or in the centre, White's attack lands first.
