I hope the >program will keep getting better. It has kept getting better. Look from where is started. The predecessor is still in the list, Complete Chess System. Also I cannot share your opinion. I don't think it is weak.I also do not think it cannot COMPETE against "brute-force" or fast-searchers. In Paris it did well, using fast-hardware like the others. It competed good against Dark Thought and others. It sacced some games unsound. But this was the intention when we designed CSTal, that is should sac. Otherwise we would have named it CSPetrosian or whatever. IMO it showed good playing strength ALTHOUGH it sacced ! You have to understand that Chris is changing the engines faster than you can test them. If you test them and he produces almost ONE engine each day, you have to speed up to understand WHAT cstal is. It is moving any day. Forwards, backwards. But I do not believe it is a loser. My results speak against this. How can it kill genius (championship 1993 paderborn) and be a loser ? How can it kill junior (championship 1993 paderborn) and be a loser ? In the moment e.g. the winning position in the autoplayer game vs. genius on my 200 Mhz machines develops from a 1-0 into a 1/2 by repetition. This is still a draw. And I am sure there is nothing bad with those games, here it is BTW: [Event "60/60"] [Site "k6/200 Mhz "] [Date "????.??.??"] [Round "1"] [White "Genius5"] [Black "CSystem Tal"] [Result "1/2-1/2"] 1. e4 e5 2.
