Move Diversity and Theory Depth

There are 5 other moves seeing meaningful share, and 76.9% of games stick to established theory. Entropy: 2.38.

Common Mistakes
- Drifting away from main theory — At 400 Elo, theory adherence sits at 67.6% — versus 80.1% at 2000. The most popular deviation is Nc6 (played 19.1% of the time at 400, much less so up top). It looks fine but quietly hands the better-prepared side an edge.
- 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.
- Playing without a plan — Each Valencia Opening middlegame demands a specific approach. Decide whether the position calls for attack, manoeuvre, or simplification before reaching for a move.
