Newcomb's Paradox -- Solved!

There are two boxes A and B. A always has $1,000, and B has a million or nothing. You may take B alone or A+B. If a Guesser guesses you'll take B alone, he loads a million in B. If he guesses you'll take A+B, he leaves B empty. Do you have free will even though he knows what'll you do? Yes.

If the Guesser is perfect, you should take B alone. But what if he is imperfect? Find the solution here!
