In the first round, both my opponent and I chose paper, resulting in a tie. There's a possibility that my opponent might stick with paper again, as players sometimes maintain their choice after a tie. Even if they anticipate I might switch to rock (which is a common move after paper), they might choose paper again to counter. By choosing scissors, I can potentially beat their paper if they stay consistent, while also breaking the previous pattern. This creates a strategic advantage in this round while maintaining unpredictability for future rounds.
