Winning Strategies for Rock-Paper-Scissors

One of my more useless talents is that I'm particularly good at Rock-Paper-Scissors. As a youngster I was put into a skiing school in the mountains of British Columbia and for a week, we spent most of our time on the chairlift playing the game. (We also invented several useless and mathematically inconsistent plays including but not limited to dynamite, water-well and possum... I know, I could have been put in a box and studied.)

It's nice to see some of the strategies I came up with reproduced by the scientific community.

This is fairly similar, but not identical to the way I play (I need to keep my actual system sub rosa in case I'm ever called on to defend my title as Almighty-supreme-Rock-Paper-Scissors champion on Madison avenue.)

There's a second, amusing follow up video here.
