How to win at Rock Paper Scissors

I found this cute little article this morning: How to Win at Rock-Paper-Scissors (and also how to cheat).

Funny how the imperfections in strategy are so concretely rooted in people being bad at being random. First, from the perception of the qualities of “rock” over the other ones, and later on from the fact that people are not very good random number generators in never throwing 3 rocks in a row.

    Although I love the photo, I prefer the slightly more scientific approach:

    This is based on the simple principle that people aren’t random as well, but this program will deterministically beat any human. There are even simple HMM models which will beat every human, every time.
