I was making a suggestion towards a selected subset of tbs., as a kind of
performance compromise (to reduce slowdown effects but at the same time, get
most of the practical 5-piece benefit = R vs. R):

I wouldn't mind if you would test all types of engines in the endgame tests
(those which access tbs. and those which do not). If you test in Fritz, the GUI
will provide "some" tbs. support if the engine in itself cannot, but only in
tablebase positions if they are reached in the game. This is in contrast to
other GUIs like WinBoard which don't do this. It is a philosophy question, how
to handle this. I would think, it is more typical for a normal practise to let
the software make use of such a function, than to unneccessarily restrict
engines when the GUI could help them to perfectly finish a game. OTOH, that may
lead to (some) results which an non-tbs. engine could not have achieved in
another GUI.

P.S. My opening book PB12moves is involved in the CCRL tests! :-) I'm glad that
I could offer something useful that way, as it seems.
