In round 1, I won using paper against the opponent's rock. Based on behavioral patterns in rock-paper-scissors, players who lose often shift their move – frequently opting for the move that would counter the opponent’s winning move. Since I played paper and won, it’s likely that the opponent will switch from rock to scissors in attempt to beat my paper. To counter a likely switch to scissors, the best response is rock, as rock beats scissors. This strategic choice maximizes my winning potential in round 2.
