I observed that in previous rounds the opponent switched between rock and scissors, and in rounds 6 and 7 they played scissors to take wins from my repeated paper choices. To counter this, I’m expecting either a return to rock (which I would tie with rock) or a possible repeated use of scissors. By choosing rock, I secure a tie against rock and potentially a win if they revert to scissors. This seems like the best tactical choice given the scoring and patterns so far.
