Looking at the pattern of my opponent's moves, they've chosen paper in 3 of the last 4 rounds (rounds 5, 7, and 8). This suggests a tendency toward paper that I can exploit. While my opponent might anticipate me choosing scissors again after my win in round 8, the statistical pattern favors scissors as my best move. With the score at 3-4, I need to win this round to have a chance at tying the game, so I'll counter their apparent paper preference with scissors.
