Looking at the previous rounds, I notice a potential pattern in my opponent's moves. They played paper-rock-scissors in rounds 5-7, which could suggest they might continue or restart this cycle with paper in round 8. Additionally, my opponent has chosen scissors in 3 of the 7 rounds so far (rounds 2, 4, and 7), suggesting they favor this move. Since I haven't played scissors since round 3, it might be unexpected. If they're anticipating me to play rock (which worked for me twice), scissors would be a good counter to their potential paper play.
