Based on the pattern analysis, my opponent has shown a tendency to choose rock in odd-numbered rounds and vary between scissors and paper in even-numbered rounds. In round 6 (even), they chose scissors, so they might choose paper in this even-numbered round 8. Choosing scissors would give me an advantage against paper. Additionally, my opponent has only chosen paper once so far, which was in an even-numbered round (round 4), further suggesting they might return to paper for this round.
