Information for the stats.

Stockfish provides Win, Draw, and Loss probabilities for each player based on engine vs. engine data.

Game Point Loss (GPL) represents the number of points lost by a player by making “sub-optimal” moves compared to the engine. A point loss of a move is the difference between expected value of a player’s move and the best move according to engine Win-Draw-Loss probabilities. The lower the GPL, the better the player played according to Stockfish.

Note that in Norway Chess, a win earns 3 points, while in a draw, the Armageddon winner gets 1.5 points, and the loser gets 1 point.

The Game Intelligence (GI) Score is calculated by subtracting the player's GPL from the game result. This score combines human decision-making and engine evaluations in a single measure. If the game isn’t finished, then expected GI score is provided.

If both players play perfect engine moves, their GI would likely be 1, given that the majority of engine vs engine games end in a draw. However, when a player takes a calculated risk that results in a win, their GI could rise above 1. Moreover, if one player plays perfectly while their opponent blunders, then the GI has the potential to reach as high as 3.
