Hello Leonid!

You should try to find titles for your beautiful creations!
For this one I suggest "The King", for obvious reasons  :-)

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".

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.  But this one is a hard nut
for Chest.  I have done some investigations into the variants Chest does
compute... and I'm not pleased.  There are lots of partial solutions
within the tree, and there are quiet white moves involved.  The trees
get really huge :-(

So... that "US" appears to be a good example for a problem where Chest
does not do very well.  I will try to use it to improve Chest, but I'm
not yet sure, how exactly that improvement has to look like.

Anyway, many thanks for your creations!  They _are_ helpful at least for me.

Cheers,
Heiner
