Question An item is up for auction. Player 1 values the item at
3 while player 2 values the item at 5. Each player can bid either
0, 1, or 2. If player i bids more than player j then i wins the
good and pays his bid, while the loser does not pay. If both
players bid the same amount then a coin is tossed to determine who
the winner is, and the winner gets the good and pays...
