Looking at the pattern so far, my opponent has gone rock → scissors → paper. If they continue this cyclical pattern, they'd play rock next, which would beat scissors. However, I've chosen paper twice already (rounds 1 and 3), so they might anticipate me choosing paper again and play scissors to counter. By choosing scissors myself, I can either tie if they choose scissors or win if they choose paper. Additionally, mixing up my strategy after showing a preference for paper keeps my play pattern less predictable.
