Looking at the pattern of my opponent's moves, I notice they've chosen rock 3 times, paper 3 times, and scissors 2 times. In the most recent round, they chose rock, and there seems to be a tendency for them to not repeat the same move consecutively. Given that the current score is 2-4 in their favor, they've already secured at least a tie for the overall game, which might make them play more conservatively. Rock would be a conservative choice for them in this final round. Additionally, I won with paper in the previous round, which could make me more likely to stick with a winning move. Considering these factors, I'll choose paper to counter the anticipated rock.
