Here is the FEN of the hypothetical positon that Shirov analyses to 'prove' that chess programs can't find the mate. I immagine he believed in writing that the programs were incapable of finding the quienscent move Kf2! that is needed to mate. Curiously, CM6000 (& the King), find the mate almost instantly! And a number of the other currently strongest programs find the mate in between 30 seconds to 3 minutes as well. 6r1/2rp1kpp/2qQp3/p3Pp1P/1pP2P2/1P2KP2/P5R1/6R1 w - - 0 31 I've noticed a dissapionting tendency of some of the top GM's, (and some other strong player's as well), too say bad stuff about chess software programs. Its always a pleasure when they are proved wrong! - After all, for the most part, they are not the one's buying them are they? In fact I suggest a pole question (or research topic), be, How many GM's and IM's percentage wise, actually buy and use these programs, with their own money, and not given to them by manufacturer's to promote the product(s)? mrslug - the ikompetent chess software addict!
