I would say now to Karlsson (head of the list) who asked me those 2 >computers: "You are a surgeon, you can pay for your own hardware"." When i asked a few years ago whether i could put diep at SSDF, Karlsson shipped me email that he could only garantuee diep to be quickly on the list if i would ship him a computer or 2. "As we are in big lack of hardware". I then heard from someone else he is a surgeon. >The following comment also needs a bit of clarifiying: > >"Further there gets used a lot of tricks in SSDF.

All these tricks are there. Just try it yourself and measure. >The way it is phrased, one could easily end up thinking the SSDF actually uses >single CPUs to play the matches, as opposed to two separate computers. I'm sure they play basically single computer now. Either that can have 2 processors or 1. >I mean, you'd think that all UCI engines were immediately condemned, instead of >the no. 1 in the SSDF list actually being a UCI version of an engine as is the >case. Shredder interface has its own tricks. Sorry features. In general less than chessbase but he has little choice of course. I do not know how SSDF tests shredder, whether they use the native shredder book in shredderclassic or shredderbook in fritz + uci engine. In the latter game it would get toasted as it would get 1 MB hashtables. If not then chessbase has given order to not trick shredder with the 1MB trick. I did not test that latter. Perhaps some can try here. It's interesting to know the motivation and tricks applied by chessbase. I try to keep updated. For now there is just too many tricks. And majority we cannot check even, because the games are not there. > Albert
