Paul, I am lost a little bit between your and mine messages but this message is
really valuable! I think that Genius 5 use some kind of selective search and
successfully. It could be that it have even this selective search in Genius 2
but I was not able to see it. This make Genius mate search even more impressive
for me.

Paul, what exactly you wanted to say when you said "artificial mates"?

Thanks, Paul, for your trial!

Leonid.
