Few years ago, Chrilly Donninger explained to me personally, that it is not possible, to get correct mate scores with hash tables (!!??). Later, he explained, that it does not matter, to get correct mate scores (which I would agree to, when it is really guaranteed, that the engine will deliver mate in all circumstances. Still I would not like a mate in x score, when it really turns out to be only mate in x+n with positive n. I of course, prefer to have may engine only show mate in n, when it is a strict lower or upper bound.) In this context, can anybody show the mate in 16, or do we have to doubt it? When Hydra is still using "vague" mate scores, I would not be too impressed. Also, no mention, if Hydra used TBs. With TBs finding mate in 19 seems not too difficult; I assume many engines will find it in reasonable time. In the concrete position, probably almost any engine will win - so it does not really matter, what score it shows; be it +7 or +20 or mate in x. Regards, Dieter
