9/6/2014 3:59 PM, FritzBlitz: Gnu BG (4 ply) says 24/22 13/10 is superior by .021. This way, your opponent has 8 hit and cover numbers and 2 double hits which doesn't seem too bad with 8 hit and covers and 2 double hits fo black. Any ideas why there might be such a huge difference between XG and Gnu BG?
