There are two bidders for three items.
Codebook:
* worth $40,000 to the White Spy, $10,000 to the Black Spy
Fake passport:
* worth $25,000 to each
Sniper rifle:
* worth $10,000 to the White Spy, $40,000 to the Black Spy
White Spy has $100,000 to spend, Black Spy $50,000.
Both make one closed bid, naming a sum for each item.
White Spy does so by having the auctioneer bid for him, using instructions based on all available information, which does NOT include the bid of the Black Spy. However, the Black Spy is aware of the exact instructions by the White Spy.
What are the optimal instructions for the White Spy?
What should the Black Spy then bid?
