Assuming your king is the white one:

You need to convince all the black pawns that sacrificing themselves to the strange machine will turn them white in the afterlife… or some other political racist bullshit

You are playing with the WW2 dlc you can call in an airstrike

“The King must die so that the game may live!”

If you can get a pawn to the other end of the board, you can turn it into a Scarlet Pimpernel.

This is very inappropriate. There are kids in this community. Please call it chess.c*m

Depends. Are Jokers still wild?

You can force a tie by convincing the mob that the black king is also a king so it must be also executed at the same time as you
