Given that I'm currently ahead (2 wins vs. 1 win), the safest option is to avoid a loss in the final round. Analyzing our opponent’s past moves, he’s used rock 4 times, scissors 3 times, and paper only 2 times. Choosing rock minimizes my loss risk because rock only loses to paper, which is the least frequent move. If he chooses rock, it’s a tie (which is enough for me to win overall), and if he goes with scissors, I win. In contrast, paper would lose more often against scissors and scissors would lose more often against rock. Therefore, rock is the safest and most advantageous move for round 10.
