Well now everyone knows that rock is the most popular (suggesting you should throw paper), meaning scissors is the best way to start, the smart money will move to throwing rock, which of course means the really smart will start with paper, so to really get the edge you throw scissors. No, wait...
Unfortunately the NS source article is paywalled, so we miss the part where they give the (probably small) improvement in odds that scissors (currently) gives.
The interesting part about RPS for me is the evolutionary/ecological/game-theoretical implications, "Some of the male lizards (call their type "rock") use force, invading the territory of fellow males to mate with females. Others ("paper") favor deception, waiting until females are unguarded and sneaking in. Still others ("scissors") work by cooperation, joining together to protect one another's females. The three types of lizard... are locked in a cyclical sort of standoff. "
And this is one of the main reasons why you see thinly disguised RPS game mechanics in most strategy games, esp. multiplayer online games. Cycles of pwn are the easiest way to prevent absolutely optimal strategies (the I Win Button syndrome).
Interestingly enough, I played in the World Series of Roshambo a couple years back. In the second round I put what Gavin Smith calls the worst beat in the history of the sport on him. It was best of seven, and he got me down 3-0. On the fourth throw I balked, which is a permissible stall tactic. After that I had a feeling he was going rock, so I threw paper. The same happened for the next three throws and I moved on to the next round.
I've been told by a few people that if you look very closely, you can see me throwing paper on the ESPN coverage.
That's the strategy I use while playing against jsomers, but while playing against chengmi, I always use (seconds+2)%3. (Unfortunately, chengmi's watch is 2 seconds fast (or 1 second slow), so he still ends up winning...)
> Alternatively you could throw the move that would have beaten your opponent's previous move. The logic here is that players subconsciously try to beat their own previous move.
Wouldn't that mean you should throw the move that beats the move that would have beaten the opponents previous move?
This line of thinking happens in high level rock paper scissors. You need to predict exactly how many levels deep your opponent is going. Professional RPS players will often throw six or seven doubles in a row before someone wins.
emfle is making a more straightforward point: if you anticipate your opponent will try to beat his latest move, you should not try to beat his latest move too; that would be shooting for a draw.
