In spite of Dr. Hyatt's admonishment that this was a loser in Crafty, I'm bent on trying it. Since I do legal move generation I can do the pins for half price - I either have or can use the pin data for one side in conjunction with generating moves. I just finished the routine. My NPS dropped by just over 4% on bench test psitions. I've just started testing an hope to have some indication if pin detection is a win, lose or draw in a few days. One aside - the pin detection is not always more accurate (or mine isn't). In the following position for the move Nxg5 the no-pin SEE correctly returns +1 where the pin-detection SEE comes back with -2. [D] 7k/4q3/8/6p1/4N3/5N2/8/4K3 w - - Fixing this would require keeping track if the pinning piece enters the exchange, which I'm afraid would bee too expensive. Dan H.
