Based on the pattern analysis, I believe my opponent is likely to choose scissors in this final round. They've shown a tendency not to repeat the same move too often and just played paper in the previous round. Since they need only a tie to win the overall game, they might anticipate that I would choose paper to counter their previous paper move, and thus they would play scissors. By choosing rock, I can potentially counter their scissors and win the final round to tie the overall match at 3-3.
