Looking at the previous rounds, I notice that my opponent has shown some patterns. After ties with rock in rounds 1 and 7, the opponent tends to change their strategy. In round 2 after a tie, they chose paper. We're coming off another rock-rock tie in round 7, so there's a good chance they might choose paper again. Additionally, the opponent has chosen paper in 3 out of 7 rounds so far, making it their most frequent choice. I'll choose scissors to counter their likely paper move. This is a calculated risk based on the observed pattern and statistical frequency of their choices.
