Split or Steal?

The UK game show Golden Balls (don’t laugh) asks the two participants who make it to the final round to split their win using a variant of the prisoner’s dilemma. A typical final round of the game looks something like this: heavy on bluffing and serious-faced human drama. What happened when one participant applied a little game theory is rather different. It is worth watching just for how everybody else reacts to the smirking instigator’s strategy.
