I've noticed a pattern where my opponent seems to be making choices that counter mine each time. If this pattern continues, they might expect me to choose paper this round (continuing the cycle of rock→scissors→paper). By choosing rock, I'm breaking the pattern they might expect. Additionally, they've used rock once, paper once, and scissors once, showing no strong preference, but if they're tracking patterns, they might anticipate me choosing paper and counter with scissors, which my rock would beat.
