Waiting for your friend
Rock paper scissors looks trivially simple until you are playing it against someone who actually understands how people think. Three moves. No board. No pieces. Just two people simultaneously choosing from the same three options and hoping.
The game is older than most people realise. References to hand games with the same rock-beats-scissors-beats-paper structure appear in Chinese literature from the Han dynasty, around 200 BC. The version most of the world plays today spread from Japan in the 17th century, where it was called jan-ken. It reached the West in the late 19th century and has been used ever since to settle arguments, decide who goes first, and occasionally determine the outcome of things that probably deserved more careful thought.
The World Rock Paper Scissors Association has run international tournaments since 2002. Yes, this is a real organisation. Yes, there are professional competitors. Yes, skill is genuinely involved, at least against human opponents.
Against a computer that picks moves randomly, yes. Against a human, no.
Research from the World Rock Paper Scissors Association across thousands of competitive matches shows that people do not pick randomly even when they think they are. Rock is chosen about 35 percent of the time, scissors about 35 percent, and paper only about 30 percent. Nobody picks paper as often as the other two, possibly because it feels passive compared to a fist or a blade.
The deeper pattern is what happens after each round. Players who win tend to repeat their winning move. Players who lose tend to switch. This sounds obvious but it is genuinely exploitable. If your opponent just beat you with scissors, there is a better than random chance they will throw scissors again. Which makes rock a better than random choice for your next move.
None of this works against the computer on this site, which picks genuinely at random with no pattern reading. Against another person, these tendencies are real. A Best of 5 match gives you enough rounds to spot them.
If you have no information about your opponent, throw paper. It beats rock, which is the most commonly chosen move. That is the full optimal first-move strategy when you know nothing.
After that, watch for patterns. Does your opponent repeat when they win? Do they cycle predictably through rock, scissors, paper? Do they default to rock when they have not thought carefully? Most players have tendencies they do not notice. Spotting them before they spot yours is what separates a good rock paper scissors player from a lucky one.
The hard part is staying unpredictable yourself while reading your opponent. The moment you develop a pattern you are handing them the same advantage you are trying to exploit.

Rock crushes scissors. Scissors cuts paper. Paper covers rock. Each choice beats exactly one option and loses to exactly one other. No move is inherently stronger than any other over the long run, which is why the game works as a tiebreaker.
Not consistently. The computer picks moves with a genuine random number generator and has no patterns to exploit. Over enough rounds, wins, draws, and losses should come out roughly even. The only way to get a real edge is to play against another person, where human psychology introduces patterns that can be read and exploited. Switch to vs Friend for a proper competitive match.

Choose your format before the first round. Best of 3 goes until someone wins two rounds. Best of 5 requires three wins. Infinite keeps going until you stop. A single round is fast but gives luck too much influence. Best of 5 is long enough for patterns to emerge and strategy to matter.
Nobody knows for certain. The leading theories are that a closed fist is the natural resting position of a hand, requiring less conscious effort to throw than opening fingers for paper or splitting them for scissors. There may also be a psychological association between rock and strength or aggression, making it feel like the powerful choice under pressure. Whatever the reason, paper exploits this tendency and is statistically the best opening throw against an opponent you know nothing about.
