Very interesting example! Another might be in Formula 1 racing. Certain driver's (Senna [1]) have been known to force passes by putting the other driver into a no-win situation. The passing driver might dive to the inside of a turn with no hope of slowing enough to avoid hitting the car they are passing. Their only hope is that the other driver will decide to avoid an accident, allowing the pass. If they don't make way then both drivers are out of the race. Maybe the aggressive driver receives a penalty for reckless behavior. If they do make way though, the aggressive driver now knows that they can do this again and again to this same competitor without being punished for it. Some of the greatest drivers in history (Senna, Schumacher, Earnhardt in NASCAR) had reputations for this. Another example could be unspoken collusion between poker players in a tournament. When one player is all in with their tournament life on the line they may be called by multiple other players who have more chips than them. These other players can still bet against each other in a side pot, but often won't and may consider doing so bad form. If one does continue to bet it may force the other to fold. This improves the betters chance of winning this hand, but it also improves the all in player's chance of winning and staying in the tournament. By not betting the two callers increase the chance of knocking this player out increasing their expected winnings for the tournament.
