Looking at our history, my opponent has chosen paper twice (rounds 1 and 7), and both times were when I chose either scissors or rock. There seems to be a pattern where they choose paper when they think I might choose rock. I've used scissors successfully several times already (winning rounds 1 and 3), and since I'm ahead 4-1, I'll continue with scissors to potentially counter their paper play. The opponent may be expecting me to switch strategies since we've had two scissors-scissors ties, but I think scissors remains my best option to secure another win.
