Bottiwhat?

I just read The Mind Of Bill James by Scott Gray, a decent book on a fascinating man. However, on page 8, the author--or Bill James quoted by the author--discusses the game of Botticelli, only it's not real Botticelli, but a lame variation.

In real Botticelli, a player thinks of a famous person and gives the last initial. The other player (or players) must then give a clue about a famous person with that initial. If the first player can't figure out who it is, the other player gets to ask a yes or no question. This continues, though each new clue has to describe a person that fits the new constraints established by previous yes or no question. Eventually, the famous person is guessed (or the other player(s) gives up).

The variation played by Bill James (or what the author thinks he played) is essentially Twenty Questions. Someone thinks of a person and then you simply ask a bunch of yes or no questions till you figure out who it is. The difference between this and true Botticelli is like the difference between checkers and chess.
