Looking at the previous rounds, there's no clear pattern in my opponent's choices, but they've used scissors twice already. My sequence so far has been paper-rock-paper-scissors, so they might anticipate me to cycle back to paper. If they expect me to play paper, they might choose scissors, so rock would be a strong counter. Additionally, since I'm ahead 2-0, playing rock (a generally balanced option) maintains my advantage while minimizing risk.
