Looking at my opponent's pattern, they've played rock in rounds 1, 4, and 6, and scissors in rounds 2 and 5. There seems to be a tendency toward rock-scissors alternation, with only one paper in round 3. Since they just played rock in round 6, there's a good chance they'll play scissors in round 7 following this pattern. Playing rock would be my best counter to their potential scissors. Additionally, I've had success with rock in round 5, and given my current score deficit, I need to make strategic choices to catch up.
