I guess that also some luck is involved and the consistent behaviour is not the
most expected behaviour even with a program that is relatively better with more
time.
I stopped the last match but I plan to continue it.

I may consider crazybishop later and another experiment is to use different time
control of x minutes/40 moves.

Maybe Jonny was lucky in WCCC but I guess that the main reason for Jonny's
success in WCCC relative to Movei and Crazybishop is probably not luck and not
better hardware but inferior algorithm of the opponents or inferior evaluation
of the opponents.

Time control in WCCC was more than 10 times slower than 10 minutes for game even
if you do not consider pondering.
