- The chooser picks a famous person who is at least as famous as Sandro Botticelli
- The chooser gives one of the person's initials (if it were Botticelli, I could say S or B)
- Guessers may ask yes/no questions - you can indirectly guess something like "Have you ever run for public office?" or directly ask "Are you C. Scott Grow?"
- The game ends when someone guesses who the person is or if nobody guesses for a while
