Probably we used Genius version in almost the same time. I think that I ended my
mate solver in around 4 or 5 years ago, and this is at that time that I used
Genius 2.

Recently, I went back to my solver and speeded it a little bit. Still not ended
making my changes for all 5 version of solver that I have. One month ago I had
some trouble with my old AMD and was forced to buy my new Intel 600Mhz. Now,
when I am ready to continue working with my mate solver, I expect also to use
many positions for verification, just as before. It could be that some Genius
version will help in seeing my speed. But Genius 2 look like very slow. And how
are Genius 5? I speek only about mate.

It could be that this version is written on C and it make it so slow. Genius 2
is for sure Assembler written but "free" one look not like the original that I
remember. I still must have it somewhere. New one have more Windows look. By the
way, I like very much Genius 2 graphics. Look very pretty. Thanks, Uri, for
spotting "free link"!

See you later,
