Common Mistakes
- Drifting away from main theory — At 400 Elo, theory adherence sits at 78.1% — versus 85.9% at 2000. The most popular deviation is a3 (played 16% of the time at 400, much less so up top). It looks fine but quietly hands the better-prepared side an edge.
- 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.
- 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.
