Hi John, Thanks for replying,

My other post entitled "CM8K personality tourney results-120 games" G/5
The results were for the top two as follows :
CMKKND 32H +10=8-6    14
CM Default +7=12-6    13

although overall score was within one, I thought CM KKND 32H win ratio was
more impressive than CM Defaults, and it does much better against GT-2.
