My opponent has chosen scissors in rounds 3 and 5, and rock in rounds 2 and 4. There seems to be a pattern where the opponent alternates between scissors and rock. Following this pattern, my opponent might choose rock in this round. However, I've noticed that my opponent has been countering my moves effectively. Since I've chosen paper and rock recently, they might anticipate me choosing scissors and go with rock again. Instead, I'll try to break my own pattern and choose scissors, anticipating that my opponent might switch to paper to counter what they think will be my next logical move (rock).
