I want to find >out more about your program ! We know some stuff now ...... SSDF nearly 2400 150,000 nps on the P2 300 This is comparable to Nimzo / Fritz / Ferret / Crafty. So he's either a pre-processor or a tip node processor doing fast evaluations like these. Junior was printing 13,14,15 at each iteration. Amir said this was 'half-plies'. (Frans Morsch quipped he'ld start printing quarter-plies on Fritz for PR purposes) Amir said this half ply count was full width. So he gets 7 or so full width plus extensions on tournament times. The games I saw, Junior looked to be generating king attacks quite often. At 150,000 nps I doubt he has sufficient time to effectively evaluate a good kign-attack term, so my guess is that he is pre-processing himself into these positions. This is probably random. The user-interface graphics screen is horrible. Amir spends him time on chess stuff, not looking pretty. Going out on a limb, without much evidence, I think junior is a pre-processor but has done something clever to get round the inherent problems. This had given him a good edge.
