My opponent has chosen paper once and rock twice so far. There seems to be a slight tendency toward rock, and they haven't chosen scissors yet. Since my opponent might be expecting me to choose scissors after the previous ties with rock and scissors, I'll choose paper instead. Paper beats rock if they continue their recent pattern, and if they switch to scissors thinking I'll choose paper, they would win - but this risk is worth taking since I need to start winning some rounds to catch up in the overall score.
