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.
