Yes I saw fruit is leading 4-1 against Shredder9(and fruit is losing the 6th game) but there are more games at 40/40 time control at CEGT and in this tournament Fruit is only number 3 at this moment after Fritz. I also saw results when Fruit beated Fritz at blitz see http://wbforum.volker-pittlik.name/viewtopic.php?t=2867 Fruit-Fritz 52.5-47.5 I can only say that nothing is clear based on the results. Uri
