Subject: Rybka Experiment with TheKing

Author: Mike Byrne

An interesting experiment -- ran series of matches with Rybka vs TheKIng at
Sd=1, sd=2, sd=3, up through sd=11, with no book and no pondering.  The results
are deterministic, ie. they are repeatable, at each level, the games simply
repeat thenselves -- you really only need to two games -- I ran 2  more  (and 4
more at sd=1) to ensure they were repeating.

Observations:
As sd=1 and sd=2, the games were won by black and and were even. Sd=3m Rybka had
slight avdanatge.  Rybka won both games at sd=4, TheKing won both games at sd=5,
at that thatpoint where Theking began using more time.

At Sd=6 , the games were split , although TheKing used more time. At sd=7, Rybka
won the match despite using far less time.

For Sd=8 through sd=11 Rybka won the matches except for sd=9 which was split.
At theses higher levels, Rybka generally used about 1/5 of time that the King
used.

In all cases, the matches and games are deterministic and the games began
repeating after two games.
