King's Indian Defence by rating
1.d4 Nf6 2.c4 g6 3.Nc3 Bg7
The King's Indian Defence hands White the centre and asks for it back later, so the early questions land on White. Playing e4 is both the engine's move and the popular one, and the rate rises sharply with rating.
How often each rating finds the engine move
Early findability runs 44 to 80 percent, but the position two plies deeper reverses it: 46 percent at 1000, 24 percent at 2200.

How these numbers were produced
Stockfish 18 by the Stockfish developers (see AUTHORS file) at depth 20, with MultiPV set to the exact legal move count of each position so no move is left unscored, and Maia3, chessformer, human move prediction, 5m (bundled with maia3-js, UofTCSSLab/Maia3-5M, about 5M parameters) for the human move distribution. Run on 2026-08-29 over 28 positions across 7 rating bands. Findability is Maia3's probability for Stockfish's top move; it is not a claim about win rate.
