Based on the opponent's pattern of choices so far (rock → scissors → paper), there's a possibility they'll play rock next to continue cycling through options. However, they might also anticipate that I'll try to counter their pattern and choose paper to beat their potential rock. By choosing scissors, I can win if they choose paper, which seems like a reasonable prediction based on psychological gameplay - they've already won with paper once and might try to repeat a winning move. Additionally, my opponent has won with scissors before, so they might expect me to avoid paper (which would lose to scissors again), making paper a safer play for them.
