Looking at the pattern, my opponent has chosen rock for the last two rounds (rounds 5 and 6). Given this recent consistency, there's a good chance they might continue with rock, which would make paper a winning move. Additionally, the opponent seems to have shifted away from their initial strategy of consistently countering my moves. With them leading 4-1, I need to make strategic choices to catch up, and paper gives me a good chance to win if they maintain their recent rock tendency.
