Charles, I have said this several times already:
* I don't tune my program against other commercial programs. I almost never play
Autoplayer games. I have only one autoplayer cable at home, I use it sometimes
to make sure that Auto232 still works in my DOS version.
* I don't have many of the top programs. I don't have Nimzo, I don't have
Hiarcs, I don't have ChessMaster 6000, I don't have Shredder. When I play games
against commercial programs, it's always manual games, never more than 4 in one
day, and it's always against Genius5 and Fritz2.
* Tiger's book learning is almost nonexistent. Tiger just avoid repeating lost
games. Tiger is unable to repeat a won or a draw game, except by pure luck. I
admit this is maybe a mistake, I might change my mind in a future version.
* Chess Tiger has been developped by playing against human players at my chess
club here in Guadeloupe. I have always used slow computers like 286 12MHz and
386sx 20MHz.
