At the moment Hossa needs 11 plies to see a mate in 7 (49442 nodes) and 13 plies to get the mate in 6 (615443 nodes). If you consider that Hossa ran into an endless loop until yesterday when he reached ply 11 then this is a serious improvement ;-) My goal is to see immediately (== 1 node) that black can force the pawn promotion. I think this can be done if Hossa recognize that white pawns in the pawn clusters a6/a7 and g6/h5/h4 are useless. Then you can forget all those pawns and only look at the position Kg3,Ke4,f3 where it is easy to see that black can _soon_ get a queen. Of course this needs a lot of work. >Also Inmichess loves G3-H2, you know my ugly endgame evaluation :( > >Will try it with 2.18 in the evening, maybe my new extensions help a little to >find earlier? I haven't done any work on that but we better discuss this via Email (or better: personally in Mondsee soon again :-) >As we said, hashing is a complicate thing...... >greetings to Vienna Viele Gruesse nach Mondsee, Steffen.
