Looking at our previous rounds, there's a slight pattern forming. My opponent went paper → scissors → rock in the first three rounds. If they're continuing this pattern, they might play paper next. However, they might also stick with rock since it just won. Given that the score is tied and we're both likely analyzing each other's moves, I'll choose paper. It would beat rock if they repeat their last move, and if they anticipate me choosing rock and play paper themselves, we'd tie. This balances defensive and offensive play while avoiding being too predictable.
