Did you look at the positions? Do you think that the sides have equal chances? The point of Thorsten Czub in his posts some weeks ago was that Fritz's problem was always that it evaluated 0.00 when it is easy to see that both sides do not have equal chances and I remember that he talked about a possible future situation when future fritz shows 0.00 whenfuture shresser understands what is going on. I think that wrong 0.00 happens to every program. Uri
