Thanks, Paul! It is much better that what I found. I knew only that selective
search found mate in 11. By brute force I reached only 6 moves, seeing that 7 on
my program will take already too long. It could be as long as 24 hours and more,
after my branching factor. Even if I am not ready for installing now in my DOS
program hash (it help a lot in brute force search) I am tented to come soon to
my mate solver and try few ideas for speeding up its brute force part.

Greetings to you from Canada,
Leonid.
