Looking at my opponent's pattern, they've chosen paper three times (rounds 1, 3, and 5), scissors twice (rounds 2 and 4), and rock once (round 6). There seems to be a potential pattern of paper appearing frequently in their choices. Additionally, after using rock in round 6, there's a possibility they might revert to paper, which is a common psychological move after playing rock. Since I'm currently behind in score (1-2), I need to make strategic choices to catch up. I'll choose scissors anticipating they might play paper again, especially considering their tendency to use paper more frequently than other options.
