So the tablebase depth parameter sets the ply depth, at which Fritz starts to
access the tb's, is this correct? (I didn't understand this settings until now -
thanks!)

But the behaviour in the position above is still buggy, because when Fritz is up
a pawn (on the 7th rank!), why doesn't it consider other continuations than the
repetition, even at depth 2?

It's a bug.
