Beowulf has skill modes, and implementes them pretty simply. Basically, it just gradually removes the search improvements one by one, adds randomness into the move ordering, adds randomnes into the positional evaluation, and disables the hash table, etc... I think this is pretty much the only acceptable way forward. Even *ColChess* still beats me when searching to 2 ply if I'm playing fast Blitz games. (Of course it has quiescence search too...) Yes, I _am_ that bad, BTW. I'm not sure what kind of ELO the lower skill levels play at. It's probably still around 1800 or so I'd expect on decent hardware. Cheers, Col
