Hi, Paul!

You did better that me. Mine found by selective in 12 moves deep in 5 seconds.
Brute force was slow and I stopped searching right after 8 move.

This night could not sleep because of people that did a lot of noise one floor
below. In order of doing something, went to the Web to listen my radio programs
and put this position in the same time.

Cheers,
Leonid.
