Move Diversity and Theory Depth

There are 4 other moves seeing meaningful share, and 69.1% of games stick to established theory. Entropy: 2.69. By 2500, Be2 dominates at 64.6% of replies; only 2 viable alternatives remain and 96.6% of moves are theory. Entropy drops to 1.27. The narrowing is significant — strong players consolidate around a small set of best moves, while amateurs scatter across many plausible-looking options.
Main Lines and Variations
From the position after 1.d4 Nf6 2.c4 c5 3.d5 e6 4.Nc3 exd5 5.cxd5 d6 6.e4 g6 7.f4 Bg7 8.Nf3 0-0, the recognised continuations are:
Each branch leads to a different middlegame character — the resulting pawn structure decides what kind of game you get.
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.
