Thanks for playing the match, Kurt!
Did you use the default selectivity of 4 for Gothmog throughout the match, or did you
change to 6 in the last few games?

Hi Tord
I used the default settings with selectivity=4 otherwise I would have
mentioned that. Now a 40'/40 match vs Junior7 is running with sel=6
but it's too early to say something concrete. This time I took a much
stronger opponent to find some weaknesses of Gothmog 0.4.7.
