It has occurred to me that it is wrong to evaluate a position in terms of relative pawns (the "de facto" standard - whereby an evaluation of 2 means that you're approximately the equivalent of 2 pawns ahead). This means that many aspects of evaluation have to be squeezed into a dimension which is not appropriate at all. A better way would be to evaluate "winning probability". If a position was a draw, the value would be 0.50 (or 50%). If the player should win 3 out of 4 times, the eval should be 75%. If the player must win from here, then the evaluation should be 100%. It seems strange when you think about it that all programmers have chosen to adopt the traditional "pawn equivalence" standard. -g
