Looking at the previous rounds, I notice some patterns in my opponent's play. They've chosen rock twice (rounds 1 and 4) and scissors twice (rounds 3 and 5), with a tendency to follow scissors with rock (as they did in round 4). Since they just played scissors in round 5, there's a chance they might play rock again. However, they might also be recognizing that I've been cycling through scissors→paper→rock→scissors→paper, which might lead them to anticipate me playing rock next and countering with paper. By choosing rock now, I'm slightly breaking my own pattern while also being prepared if they play scissors again, which they've shown a preference for. Given the score deficit (1-3), I need to make a strategic choice that gives me the best chance to catch up.
