Common Mistakes
- Drifting away from main theory — At 400 Elo, theory adherence sits at 87.5% — versus 95.8% at 2000. The most popular deviation is Nc3 (played 25% 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.
- 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.
