Brinkmanship is where we give up all the negotiation effort and advance on the opponent forcing him to retreat. In the chiken game, in which both participants advance the car towards each other at full speed, one of the players removes the car's direction and throws it away, showing everyone what he has done, thereby forcing the other player to detour rationally to save your life.
