The single most likely result >will be 10-10 but this will still be a fraction of the time. The nunn match has only 20 games. It is a symmetric match without opening book from 10 known positions every position is played twice(one time fritz is white ans 1 time Junior is white) I did not say the new Junior is significantly better than fritz5 but significantly better than the old one(the old one lost 14.5:5.5 in the nunn match) Uri > >- Don
