Analyzing the rounds, I looked at the opponent's choices: paper in rounds 1, 5, and 8; rock in rounds 2, 4, and 6; and scissors in rounds 3, 7, and 9. While they’ve used all three moves evenly overall, there’s an interesting tweak: the opponent’s move in even-numbered rounds (2,4,6) has consistently been rock. Given that round 10 is even, it’s plausible they might lean toward rock again. To beat rock, the best choice is paper. Hence, I choose paper for round 10.
