I remember when David Kittinger took the B+N mate info out of the Forte computer (It was in it's predecessor the Super Constellation). I asked him why and he said he needed the memory for something else. I never bought another Novag computer after that. ******* and >every tester must look at as a matter of fact.

Tablebases will fix many of these problems. I am a very strong advocate of tablebases even if their contribution to rating points is minimal. But I repeat, the final decision as to what a program will or will not do lies with the programmer-_N_O_T_ the beta testers. Do you believe Christophe does not know that Chess Tiger will not mate with a Knight & Bishop? Jim
