Performance Across Rating Levels
Popularity and results vary sharply by rating level. The 1200 bracket has 2,775 games (0.00% of all games at that level); White wins 53.7%, Black 42.2%, 4.1% are drawn. At 1800 the opening surfaces in 0.00% of games; White wins 50.5%, Black 44.4%, draws 5.1%. At the top end (2500+ Elo), popularity is 0.04% with 9.6% draws — a clear sign of how much theory rules the line at master level.

Move Diversity and Theory Depth
What players actually play after the opening moves depends heavily on rating. At 1200 Elo, the top reply is O-O, played 67.4% of the time. There are 3 other moves seeing meaningful share, and 89.1% of games stick to established theory. Entropy: 1.66. By 2500, O-O dominates at 89.5% of replies; only 2 viable alternatives remain and 99.7% of moves are theory. Entropy drops to 0.52. 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
- Playing outside main lines — At 400 Elo, only 85.5% of moves follow established theory — at 2000 that climbs to 98.3%. Most of the gap is players who pick a reasonable-looking move over the best one, and the position quietly drifts.
- 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.
- Playing without a plan — Each Dutch Defence: 1.d4 f5 2.c4... 5.Nf3 middlegame demands a specific approach. Decide whether the position calls for attack, manoeuvre, or simplification before reaching for a move.
