They wouln't since they'd lose, just try it in CB's friendly mode in >where choosing 0.50 has this effect, 1.00 is just slightly better than 0.99, Slightly better, means that with a 1.0 one player IS NOW a full pawn ahead. No game is won or lost by "hundredths" of a pawn. No game is Won by a "Partial" piece either. A Bishop, or Knight is evaluated at 3.0 Pawns; Rook at 5 pawns until the eval is 3.0 or better, no player is a full piece ahead. >0.99 doesn't mean "neither side has an advantage" just as 0.50, 0.49, or 0.51 >doesn't mean either. > >Best Regards.
