Hi, Paul!

I went to see this position in 8 moves. Mate really existe in 8, like you said,
and mine moved: White Knight B5-D6. I have no idea about 7 moves. See 7 moves by
brute force can take very long time for my program. When I solved position with
selective search for 8, it already took 6 min 41 sec. Brute force for 7 can take
easely few hours.

Greetings from Montreal,
Leonid.
