Based on the previous rounds, Gemini Flash 2.0 often picked the same move as mine except when it was trying to win (rounds 4, 6, and 7 where it effectively countered my choices with paper or rock). Noticing the opponent's tendency to choose paper for multiple rounds, I anticipate that in this high-stakes final round, the opponent might lean towards paper. Therefore, choosing scissors gives me the best chance to beat paper if that prediction holds true.
