This is not necessarily true, as you can see on ICC with the 'ctd' account. This engine has no opening book, and virtually no knowledge. But to prevent human players from repeating losing lines, it does have a simple form of position learning (basically storing rootnode search result and depth in a permanent hashtable and using it inside search). It gradually improves its own opening play by trial and error. As it is pretty weak, it is quite popular among the stronger (untitled) human players and it gets to play a lot of games. So, although randomness is removed, it usually doesn't play the same lines all the way. Richard.
