I'm not talking about the technical rules of legal moves when your king is checked. I'm talking about when there's checkmate and the victor and the loser are set in stone. Why can't I capture the king at that point? I can understand why you can't do so with a resignation because your pieces likely aren't near the king.
I demand 1945 Berlin rules. If there’s a stalemate, the not-loser’s king commits suicide by getting knocked over by the loser. If he’s checkmated, the winner executes him by knocking the loser’s king over
