You're asking for a program which moves instantly if it's in a "familiar" position that it has searched deeply enough already. The only program I know with this feature is Chenard, by Don Cross. http://www.intersrv.com/~dcross/chenard.html As you noticed, this feature interacts with opening book learning. Who wants the program to instantly repeat all the moves of a game it lost--how boring! Chenardonly stores positions up through move 15 of the opening. Your solution is to let the program think overnight analyzing openings (or it could use idle time between games). This is called offline book learning. Almost all chess programs with opening book learning use online learning, meaning that they don't need any (appreciable) extra time outside the game itself to do their learning. The only chess program I know with offline learning is Hossa by Steffen Jakob: http://www.jakob.at/steffen/hossa.html Offline opening book learning is much more powerful than online learning. I'm rooting for this feature too. Jay
