Get Rich Quick Scheme No.47
Legally change your name to Bobby Fischer. Then write some half baked chess books. Like, Bobby Fischer Teaches Chess 2 and My 60 unforgettable games. Some other book ideas, My Systems, Think Like A Tree...erm that wont sell, I know, Think like an International Master. One more The Art of the Immortal Game, any chess books that starts with "The Art of" is guaranteed sales.
