Better luck next time

There's a cute little bit in today's NYT about everyone's favorite tie breaking game:Ro-Sham-Bo.

After some vigorous training, the author enters a professional Rock, Paper, Scicors tourney. Right before the first round begins she locks eyes with her opponent and says, "I'm throwing rock."

The poor guy thought to himself, "If she is, she expects me to throw paper, in which case she would throw scissors, in which case I should throw rock. If she really will throw rock, then at worst we would tie."

The result: He threw rock. She threw paper. She won.

As she notes, it's a very Princess Bride kind of logic.
