Hi Uri >Let me understand. >Suppose White has 40 pseudo legal moves when black has 30 pseudo legal moves. >Do you give white bonus of 1 pawns? Yes that is exactly right. Do other people also count pawn mobility in the function ? I didnt do this as I thought it probably wasn't that useful and it improved speed a tad. >I think that in this case the bonus is too high. >I suggest that you try smaller values. >I read in the past a claim that a bonus of 0.03 pawns for square may be the >best. Thinking about it again I guess that this is a good example of a mistake a beginner is likely to make. Once you spend time working on adding a feature, the temptation is to make the alteration too effective, causing an over compensation. I will modify it to 0.03 and give it another test Thanks for the help Geoff
