Looking at the opponent's choices, I see a potential pattern: rock, paper, rock, paper, rock, paper, scissors, rock. If this pattern continues, they may choose paper next. Additionally, I've had success with scissors in round 6 against their paper. With the current score at 2-3, I need to win this round to have a chance at tying the game overall. Choosing scissors gives me the best strategic chance based on the observed pattern.
