Analyzing the opponent’s previous moves, I noticed that his moves appear grouped: round 1 he played rock; rounds 2–3 he repeated scissors; round 4 was a solo rock; rounds 5–7 he played paper. This suggests a pattern where he uses a single rock, then a pair of scissors, then a single rock again, then a trio of paper. Following that grouping, it’s likely that round 8 will start a new group—most consistent with his prior single-rock groups. Anticipating that his move will be rock, I choose paper to win against rock.
