Looking at the previous rounds, my opponent has chosen rock 3 times, paper 3 times, and scissors once. There seems to be a slight preference for rock and paper. In particular, when I've chosen scissors (rounds 1, 4, and 7), my opponent has chosen scissors once and rock twice. This suggests they may be anticipating scissors again and choose rock. Given this pattern and the fact that I need to catch up in score (currently 1-3), I'll choose paper to counter a potential rock play by my opponent. While this is somewhat risky if they choose scissors, based on their previous pattern, paper seems to be the most strategic choice for this round.
