You know much about the endgames >tablebases, what you find that would happen? 7 pieces, >9 pieces, in the endgames tablebases? > >Best regards, >Paulo Soares No. Lets take a gross estimate and say a 5 piece file (with promotion cases) like krpkr, krnkr, krbkr, krrkr and kqrkr takes roughly one gigabyte. Then a 6 piece set will take 64 gigabytes (plus a bunch of memory to build). And a 7 piece set will take 64^2 gigabytes == 16 terrabytes if my math is right. So 7 piece files are a _long_ way off. Some 6's are doable now, but they are very big themselves. But probably within 2 years we can assemble a machine with some 100 gig drives (say 32) and do some damage to 6 piece endings.
