A puzzle I learned from Joel, originated from Peter.
Given a deck of card face down on the table, now I flip the card one by one. Each time you can bet any amount of money from you have in hand. Say if you bet $50 for the first one to be red. If it is red, then you get $50 extra. Or, you lose $50.
You are given $100 to start with. Now the question is what is the maximum amount of money you can always win.
The answer is about $900, with a cute argument.
