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 O-O, played 44.3% of the time. There are 5 other moves seeing meaningful share, and 75.7% of games stick to established theory. Entropy: 2.41. By 2500, O-O dominates at 66.5% of replies; only 3 viable alternatives remain and 96% of moves are theory. Entropy drops to 1.38. The narrowing is significant — strong players consolidate around a small set of best moves, while amateurs scatter across many plausible-looking options.
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.
- Letting White own the centre — Hypermodern openings concede central space on purpose, but only if you strike back in time. Delay the counter-blow and you end up squeezed.
