Field notes
Players give a probability-based expected score for White, where a win counts as 1, a draw as ½, and a loss as 0. The squared error is compared with a House benchmark that combines Stockfish’s position evaluation with the players’ rating gap. The page says records and usernames live in the browser; a player code can carry them to another browser, but anyone holding that code can play as that user.
