Seeing Critter's learning at work again, I'm really one more time impressed, how well tactical hard positions are kept in small session file as for their single best move and eval with just a little Forward- Backward. Only Houdini (guess it had position- learning up to version 5, at least later ones didn't have it anymore neither) and SF_PA (Preserved Analysis) from Jeremy Bernstein did do as well as that way back then. Does maybe anybody have an email- address of Richard Vida, he or she could share with me per PM?
Maybe Richard reads here now and then still, my question to him was, if he would mind Critter 1.4 getting disassembled, which without his permission of course would breach his proprietary right, regards
Peter.

I ran Critter 1.4 , with session file on , thru 1000 engine match games against a 3600 elo engine. Critter's playing style changed amazingly after these games.

Well, The King from CM9000 (now almost 25 years old) is still pretty good. Of the seven positions in this thread, it correctly solved five of them in under two minutes (and two of them in under twenty seconds), on a fairly slow machine.
