Please test it yourself. I may hope SSDF doesn't test within the fritz GUI only,
if so that would mean severe problems.

Ponder = on and off is only nonsense winboard guys can come up with.

Of course i only test myself with ponder on. I do not know about SSDF here.

In diep there were so many problems with persons by accident turning off
pondering, that diep *only* can play with ponder on. No way to turn it off.
