Which program gives the right answer in such positions then? None I >know of. Which human gives the right answer in such positions? Nobody's perfect. As an aside, it is worth pointing out that DB2 did not do too badly in that closed Ruy game against Kasparov, where Kaspy resigned in a drawn position. I think that in *general*, for the purpose of *analysis*, either type of program will do more or less equally well. Computers usually suck at such positions regardless.
