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

Bring out your ballista, or utilize your spy in the opponent king's court. You do have a few in there, right?

they're just trying to give you a chess briss.

Depends. Are Jokers still wild?
