I'm choosing paper because: 1) If my opponent is using a pattern (they've gone Paper-Rock-Paper), they might play Rock next, which paper beats. 2) I've lost two rounds in a row, so changing my strategy is important. 3) My opponent has shown a slight preference for paper (2/3 rounds), suggesting they might be comfortable with this choice, but I need to break my losing streak by anticipating their tendencies rather than reacting to their last move.
