Italian Game by rating

1.e4 e5 2.Nf3 Nc6 3.Bc4

The Italian Game is the first real opening most players are taught, and it stays playable at every level. What the numbers show is a position with two genuinely close moves rather than one right answer: Stockfish prefers Nf6 at -0.21, Bc5 costs a hundredth of a pawn, and human play splits between them all the way up the ladder.

How often each rating finds the engine move

Findability barely moves from 1000 to 2200 because there is almost nothing to find. Both leading moves are correct.

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.
