I added an evaluation routine that gives points for [number of my stones
around me] - [number of opponent stones around me] and then give
poioints for that, but that caused a significant drop in elo on cgos
(see 00:00 at 13/8 at

Maybe I should change the evaluation to
[number of my stones] + [number of empty crosses around me] - [opponent stones 
around me]

Don; are you the maintainer of the CGOS server? Tried getting it to work
on my system at home but it seems the current TCLKit is not compatible
with it. Am trying to run it at home as well so that I can quickly do a
testrun to see if a change has a negative or positive effect.
