Hi Detlef My bot is not pro jet but i build gosu games <https://play.google.com/store/apps/details?id=nl.ingele.gosugames> ( similar to waltheri.net <http://ps.waltheri.net/> ) and i found certain "odd" positions occurring in 200+ games where over 80% of the pro's chooses move A while 90% of the games picking move A is lost by that player.
suggesting pro players in certain positions choose a "sub optimal" move to me it seems that the influence of these "sub optimal" moves is diminished by using reinforcement learning for a limited time, unfortunately my implementation is not ready enough to verify this..
