The CEGT website has Shredder 9 in first place at 40/40

Thats intermediate time no ?

Toga I believe was second 31 points back

Fruit another 6 pts back

and Fritz bilbao another 5

A total 42 points separated 1st place Shredder and 4th place

Toga in my testing at 40 min was a difficult opponent for Shredder
Shredder did better in classical time control
