This is something I looked at and something that originally
caused this post:
http://site2936.dellhost.com/forums/1/message.shtml?108059
Some positions are won some are lost. There seems no consistancy.
Position #13 for example Crafty won at tourney time though Fritz 6
as I recall had won most #13's prior to that.
I will post a spreadsheet of the results similar to what I did
in my Junior 6a Nunn 1 matches on my website:
http://www.geocities.com/chessfun_1999
The purpose of those spreadsheets in the format made was to see
if Junior 6a consistancy won certain positions.

Thanks.
