Move Diversity and Theory Depth
Looking at move selection shows how forcing — or not — the position really is. Below 1600 the samples are small (15 games at 1200, 65 at 1400), so the comparison starts at 1600, with 254 games. There, the top reply is b5, played 72% of the time. Two other moves each take at least 5% of games, and the top three moves account for 92.5% of games. Entropy: 1.40. By 2500 (2,889 games), b5 dominates at 59.5% of replies; two other moves reach 5% and the top three moves account for 94% of games. Entropy rises to 1.54. Even elite players don't fully agree on the best continuation here, which keeps the position dynamic.

Common Mistakes
- Neglecting development — Extra pawn moves in the opening are tempting, especially when you "know the moves". Developing a piece each turn is the simple correction.
- Overextending the attack — Gambits look like permission to throw everything forward. They aren't — every attacking move should improve a piece. Random checks and threats burn the initiative once they fail to coordinate.
