Please note, that was discussed in the context, that this should work theoretically, also with failsoft. I don't doubt, that in an eval that show 20 pawns positional advantage often, you will only get few lazy exits. OTOH, the 10 or so instructions needed won't hurt either. Can you please show me a postion, where you get in a few plies a positional advantage of 20 pawns for on side in one line, and in another line for the same position you get 20 pawns for the other side. Also, of course I would be interested in those 2 postitions with the 20 pawns positional advantage. Note, that I have excluded pawn endgames. Regards, Dieter
