Hello again Steffen,
I checked your problem once again, but with "Deep Fritz" and found out why you
didn't find the solution with this engine. It wasn't because your pc is slow
,but because Deep Fritz can't find the correct answer(Ng5+)and as a matter of
fact it couldn't find it in 2 hours! What do you say to that? It can't do what
it's brother Fritz 7 could do!
Regards,
Terry
