Based on the previous rounds, there have been many ties (5 out of 8 rounds), suggesting my opponent might be trying to match my moves. In the last round, we both played scissors, so there might be an expectation that I'll switch to rock next (following a common pattern). If my opponent anticipates this and plays paper to counter, scissors would be my best choice. Additionally, the opponent has beaten me twice when I played rock and paper, so trying scissors gives me a fresh approach when I need to catch up in the score.
