Is my pleasure to see you once again. This last position is in reality Chinese character that signify "Day". I thought that it is not correct that I use only Latin letters as position form. Actually today I put "Day" instead of "Middle" that is too much deeper in its solutiion. "Middle" will come next. >I've not yet worked on this new creation of yours, since my K7/600 after >60 hours is still busy crunching on your corrected "US". >http://www.icdchess.com/forums/1/message.shtml?183489 >I know, you warned us :-) but I thought that would not apply to Chest. >That there is no mate in 8 needed only 40 minutes with an apparent EBF >below 10, so I expected less than 10 hours.

Absolutely the same impression I have when I see some solutions that your mate solver find. Tried even to imagin some possible ways to push my solver farther but until now not went to my code. Still the most attractive for me is my dream to start Linux learning and eventually rewrite everything for 64 bits chip. Fascinating!!! Heiner, I tried "US" on few strong program and branching factor went there beyond 100. Maybe this will make you feel better. >Anyway, many thanks for your creations! They _are_ helpful at least for me. They are helpful for both of us. Even if I was not that ready to restart my writing, because of your presence, I speeded my mate solver twice since you are here. Before I had no reason even to think that speeding mate solver have some sense. Cheers, Leonid. >Cheers, >Heiner
