Friend or Foe?

Six contestants are chosen randomly across the country. None has met eachother before, or have been in the same building with the others. Each contestants were asked a variety of questions, and whatever team of 2 did not answer the most correctly, were eliminated, but first had to decide if they were Friend or Foe with their partner. If they both chose friend, the money they have earned is split between the two. If they both choose foe, then none get the money. If one chooses foe, and the other friend, then the one who chooses foe goes home with the money, and the one who chooses friend goes home with nothing. Each round continued in the same way, only the money doubled.
