[H.G.Muller]

As can be seen, Matacz even predicted the mating move...

Where do you see that? I only see 0 scores from Matacz.
t seems some bug in the EGTB / bitbase / recognizer code (whatever it is using here).

The whole game is weird
Just compare the scores of Matacz at moves 70 and 71 !

There is Re8 in brackets after Kc8, that is the predicted move I guess.

He means you cannot talk of predicted selfmate because Matacz is not seeing any mate.

[H.G.Muller]

OK, I see.

Well, obviously the position is erroneously listed as a draw in whatever EGT Matacz is using. (Or it is erroneously retrieved as such by the probing code.) It is not a 50-move problem, the last capture was on move 82.
