Before you there are two boxes, one white and one black. Each box contains money; one has twice as much as the other. You may choose either box and keep whatever money is inside.

You choose the white box and find $100 in it.

Okay, the first rule to solving logic puzzles is to read the intro thoroughly because there's often clues and tricks in it. I've read this through a couple times now carefully and this statement still seems to be impossible to me:

Proposition 2. The amounts [that you're able to gain or lose by swtiching] are the same.

I'll keep thinking...

A question for you then:

Suppose I'm all set to pick box A. After I pick box A, should I switch?

Well what if at the last second I change my pick to box B. Should I then switch back to A after I pick?
