When I see his page hasn't been updated since 1998, I think he've lost the
password to the FTP :))))
More seriously, I plan to make a short analyse of each position with Chesstiger
15 and CM9000, 4 by 4 (about 14 threads), here are some previews :
*Chessmasters confirms quite quickly all missing mate by CT15;
*this solution is wrong :
http://www.geocities.com/TimesSquare/6298/book0403.htm#B01 , the first
subvariation is buggy "1. ... b6! 2. Nf4 b5 3. Nh3 (if 3. Kc3 then 3. ... Ng6!
4. Nh3??? Kc5 wins)", CT 15 see easily that 4.NxNg6 is draw
*at least one position have more than 1 solution, EGTB will tell you quickly
...
More later, I received my new comp next week, a barton 2800+ with 1 GB memory,
to replace my old celeron@875 Mhz.
Here is the result by CT15 in the CB interface with the function sole test suit
(15 min/pos, 96 MB hash) :
