I believe you are right about Fritz's built in AI; it certainly should not be enough to sharply distinguishing between an extraordinarily well thought blunder and ordinary random wood-pushing. As to the non-learning problem - what scares me is not a possible regular feature of Fritz, restricting the automatic learning (althought Fritz help folders don't say a word about that). I fear the bad functioning, the little glitch that may hide an entire potential collapse in crucial moments like time-bombing. It is like fungus in systemic, organic wholes: an apple with a small fungus spot is as contaminated as a an apple all black for fungus. Fritz is highly organic and so far it bears a nagging fungus, IMHO. Thank you again and bye for now, Karen
