It may sound sarcastic, but I mean it serious. Could you give a specific rule
for such easy endings, where it is just counting?

I think, many programs probe TBs rather deep in the search, so that such an
artivact will not happen too often. If it will happen, it might be an
indication, that the position was a draw already earlier. Anyway, also here I
would be interested if you could suggest a position, where you think, this may
happen.

BTW. I gave this position to Yace without any TBs, and let it analyze for a
rather long time. The PVs are rather unreliable from the first occurence of an
attached "H" to the move, because of totally overloaded hashtables (I used 30 M
hash, K6-2 475):
