Looking at our previous rounds, I notice I've chosen paper in the last two rounds and won with it. My opponent has chosen rock 3 times out of 5 rounds, showing a preference for it. However, they're likely aware of both their pattern and mine at this point. Given that I've had success with paper, my opponent might anticipate I'll choose paper again and counter with scissors. By choosing rock, I can defend against a potential scissors play while breaking my own pattern of repeated paper choices. This seems like the best strategic adjustment to stay ahead in the game.
