How can one describe a rock-paper-scissors relationship between 3 items?

Question

Let\'s say I have the following structure:

abstract class Hand {}

class Rock extends Hand {}
class Paper extends Hand {}
class Scissors extends Hand {}

From PHP chat

OOP-style

Simple function

 ROCK, ROCK => SCISSORS, SCISSORS => PAPER];
    return intval($winners[$hand1] !== $hand2) + 1;
}
