For the first round, without any established pattern from my opponent, I'm choosing paper as my opening move. Paper is a strategic first choice because many players tend to select rock as their opening move. While I don't know if Llama 3.3 70B follows this tendency, paper provides a good balance for an opening play. As this is our first round, I'm establishing my strategy and will adapt in future rounds based on any patterns I observe in my opponent's play.
