On Celeron 600Mhz. LLchess mate solver by selective search, 10 moves deep, mate
found in 0 seconds. This signify that time is less than 0.055 sec.

Actual position have very good branching factor, even for brute force search. By
brute force I went only 8 moves deep and it took for program less than 2 minutes
to respond.
