C[Chinese rules, 25 handicap stones, Komi=0.5.

Black: ManyFaces of Go 12.013 -- Level 18-kyu
White: ManyFaces of Go 12.013 -- Level 2-kyu (Monte Carlo)
Operator (manually): Ingo Althofer.

White uses dynamic komi internally, with "Rule 42".
It starts at komi=330.5. When the evaluation of its
Monte-Carlo tree search is 42 % or higher, dynamic komi
is reduced by an "appropriate" amount (until hopefully at
some point the true value komi=0.5 is reached).

In the sequel after (almost) each move of White its
current evaluation (in %) is given. Often, only the number
without the %-symbol is given.

Black computed according to the true value of komi
all the time.]

White wins (in best Monte-Carlo style) by 0.5 points:

White Score= 193.5 =
65 surrounded points
+ 103 stones 
+ 25 points handicap compensation
+ 0.5 komi

Black Score= 193 =
86 surrounded pints
+ 107 stones

In total, White used about 45 minutes of thinking time
(on a dual-core with something like 2GHz processor speed)
in this game.]
