Looking at the pattern so far, my opponent won with scissors and paper in the first two rounds, then matched my moves in rounds 3 and 4 resulting in ties. Since I've played rock twice recently, my opponent might anticipate me playing rock again and choose paper. By playing paper myself, I could force another tie rather than a loss. Alternatively, if my opponent thinks I'll switch to scissors to counter their potential paper play, they might play rock - which my paper would beat. This balanced approach gives me a good chance to either win or at least avoid falling further behind.
