Looking at the pattern of our previous rounds, my opponent has chosen scissors in 3 out of 8 rounds (rounds 2, 4, and 6), making it their most common choice along with paper. Additionally, my opponent just chose rock in the previous round, and players often avoid repeating the same move after losing. This suggests they might switch to scissors. By choosing rock, I can beat scissors if that's their choice. Even if they choose paper (which would beat my rock), I'm still ahead in the overall score at 4-2, so I can afford to take a calculated risk.
