Thanks, Heiner!

Your help is all the time valuable. This positions look like very easy and with
more, or less normal branching factor up to depth 10. At 10 it jump
dramatically. At least, it is true for my program. If mine looked 9 moves only
in 23 min. and had previous branching 6.65, it not responded for 10 moves even
after 8 hours. This signify that branching factor jumped more that two times.

Cheers,
Leonid.
