There was an amusing comment related to this over on the Metafilter thread on this earlier today which included this impressive detail:
Naturally, we did what any self-respecting half-in-the-bag Americans would do upon meeting so-called champions of the rock-paper-scissors arena on the streets of a foreign nation, and challenged them to a duel on the spot. We proceeded to go a spectacular 0-24 against our fellow countrymen, before realizing that maybe there's more to the metagame than we had previously considered.
An excuse to post my favorite RoShamBo scene ever: https://vimeo.com/210145683 , from the show Patriot. (There's a lot of context that's missing but it's hopeless for me to try to explain it. I highly recommend the show.)
That is great, I wonder if they memorised the sequence, had notes out of shot, were signalling to each other on the side away from the camera, or just did a lot of takes.
I understand this meta-strategy on an intellectual level, but I'd find it easier to fully understand with a concrete example or an interactive example. It mentions that this meta-strategy only works if your opponent's strategy is consistent. I'd like an interactive version to play with to show that. Also, I'm curious how this strategy fairs against itself.

Any competitive RoShamBo players here willing to share their metagame strategies?
