My question is how do you solve that type of problem and if there is a way to solve it without doing the code slower(of course it is easy to solve it by doing the code slower and writing something like if (score<0) { score=-score; score=score>>3; score=-score; } else score=score>>3; I thought also about using (score+4)>>3 but in that case (12+4)>>3=2 when (-12+4)>>3=-1 Uri

Uri, which medicines are you using nowadays?

I really have no clue what you are talking about.
Can you explain what the problem is?

Thanks,
Vincent

see post number 4 in page 1.
It was about some code that I have to prefer pawns in the endgame.

The problem was already solved after the post of Bob hyatt when he suggested to use / instead of >>.
