No.451 by Karol Mlynka – A paradoxical two-men selfmate! (JV)
Pressburger King (Super Transmuting King): King which definitively takes up the nature of the checking piece (and thus loses his royal status).
Royal piece: Piece that executes a function of the King on the board.

Total chameleon echo model mates by 1+1 units. (The first time mated Pressburger King.) (Author).
On being checked by the pawn, king loses its royal powers. So how can there be a mate? Mate is all about royalty, is it not ? 🙂
Yes.. I think the phrase “..loses his royal status..” in the definition is a bit unclear..
It would be interesting, if it REALLY became a “non-king”.. AND some other piece of the same colour got upgraded to royal status..
Perhaps “On being checked by the ROYAL pawn”, King definitively takes up the ROYAL nature of the checking piece 🙂
There is quite a number of hidden non-obvious rules in Pressburger King (that is why I do not like it).
In fact it immediately gains the checking piece movement power, has to defend against check by moving away, and after this movement loses royal status.
