Go up one level in this thread


See these results from a large book test experiment by M.Koppel (CEGT
participant). The test conditions were AMD 2200+ or 2700+, 35+4 or 30+3, 256 MB
hash, no ponder, no book learning, no position learning. Shredder 7.04 always
played matches against Fritz 8, a total of more than 2000 (!) games.

http://miko42.de/dasduell/duellindex.html (complete description, german)

See index lines 01 and 12. In BOTH (!) cases against Fritz 8+Fritzbook, Shredder
scored

52.5% with it's own book, but still
51.4% WITHOUT book

(and without pos.learning which probably would have improved the score even
more, from that 295 games)

I wouldn't say that amateur engines are generally dumb, but Shredder is
definetely NOT dumb without book.
