However CM KKND 32H does defeat GT-2 and CM Default at least 50-60% of the time (entertainment games only... OK cruel posters). Do you think that somehow the custom personality CM KKND 32H clears it's hash tables better than Default? It doesn't make sense but the results seem to make it appear that way.Why else would CM KKND have better results? Thanks for your time, Paul
