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

Looks like it's the french ruleset.

"The King must die so that the game may live!"

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

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

just put the tip your hat in the guillotine.

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