I do this in even more simple way. I take by "accident" diferent positions for
"Chess Life" revue and ask two program solve them. Number of plies to search is
the same and both do this by brute force. Time found say me all that I want to

I do speak about speed. When positional logic will reach speed that I consider
as good enough I will go into the finalizing of my positional logic, more
exactly my entire chess program. Only mate solving logic don't ask any
additional material when it go into work. It can be compared even now. Comparing
my actual chess program, that is not finalized, to some other that is completely
done is premature and useless. In positional logic only its basic part can be
verified for speed even now.
