Looking at the pattern of previous rounds, I notice my opponent has played paper in rounds 3, 5, and 7. There appears to be a tendency for them to play paper frequently. Additionally, my opponent has never won a round so far, which might make them more likely to change strategies and try something new. Given my commanding lead (5-0), I can afford to make a strategic choice. Rock would beat scissors if my opponent tries to break their pattern with that move. Even if we tie with rock-rock, I maintain my lead. While paper beats rock, the risk is acceptable given my current advantage.
