I'll have to delay my work on it until I'm done with "US" :-( Hopefully I will catch up, one day :-) I will not miss any of your creations! :-) >>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.

Maybe this will make you feel better. Umm, Uhh, 100+, well, yes! Now I feel better indeed! >>Anyway, many thanks for your creations!

Before I had no reason even to think that speeding mate solver have some >sense. So, a bit of competition is quite refreshing, isn't it? E.g. your "selective search" is already on my TODO list. I want to be as fast as you are :-) :-) Also, I currently work on access to Nalimov EGTBs, in order to not be outsmarted by those "normal" programs :-) That competition makes me move, also. Fine!
