Vienna Game by rating
1.e4 e5 2.Nc3
The Vienna Game is a quiet second move that keeps the position flexible, and it is one of the few openings here where the engine's choice and the natural developing move are the same thing at every level.
How often each rating finds the engine move
Flat and high across the range, 34 to 39 percent early and 54 to 59 percent late. Rating buys very little.

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.
