Bob, Thanks for the reply! >On a PV move, you search the first move and get the score.

If all the >movesfail low, then you know the first move is at least 1/2 pawn better than >all the rest, which means it is singular. Of course, if one of the other (not >the first move) fails high, you have some work to do to determine if it is >singularly better than all the rest, including the first one. Hmmm, that seems like quite a bit of overhead. >It is complex and it takes some search overhead. There is another way that is >cheaper but significantly less accurate... Now you're got me thinking - what's the cheaper way? Any hints? Thanks anyway, Steve
