After using scissors heavily in recent rounds (and losing to rock in round 9), my opponent might anticipate I'll switch to rock as a natural response. By choosing paper, I can counter this potential rock play. Additionally, I've only used paper once in the entire game (round 1), making it my least predictable move. Even if my opponent chooses scissors expecting this adjustment, a loss would still leave me tied at 4-4 in the overall match. Given my current lead, this balanced approach offers the best strategic value.
