In chess analysis, numbers indicate board evaluation in centipawns (100 centipawns = 1 pawn). A positive number (e.g., +1.5) means White is ahead by 1.5 pawns in positional or material advantage. A negative number (e.g., -2.0) means Black has the advantage. A score of 0.0 indicates an equal, balanced position.
