Looking at the previous rounds, I notice the opponent has played rock, paper, then scissors in sequence. This could be coincidental, but if they're following a pattern, they might return to rock next. However, since I just won with rock in the last round, they might anticipate me sticking with rock and choose paper to counter it. By choosing scissors, I can beat their paper if they make this prediction. Additionally, this creates unpredictability in my own pattern, making it harder for my opponent to anticipate my next move.
