The main post says
@Talisy is a sock puppet of
@REGIUMchess. There is a user in chess dot com called E02519, ardent defensor of Regium Chess, who plays the same weird moves in the opening as
@Talisy.
Game by E02519

Both games share exactly the first six weird moves by White. Both games were played in February 2020.
It appears, however, that the behaviour of the user here is less aggressive than that of the user there (fortunately).
Is this enough to deduce that RegiumChess = Talisy = E02519? Or are they just different evasive angels? Will
@kokko say I'm wrong?
One thing we know for certain is that there are at least two people involved in Regium: the person filmed and the person filming. Just as there are only two men in the team who, we strongly suspect, are not from thispersonisnotreal.
