The opponent has shown a tendency to play rock multiple times (rounds 1, 4, 5) and just played scissors in round 6. Based on common RPS psychology, they might return to rock to counter my previous scissors play. Additionally, they haven't won any rounds yet and might revert to their initial choice (rock) to break their losing streak. By choosing paper, I can counter a potential rock play while continuing to mix up my own pattern to remain unpredictable.
