My opponent has played rock in the last round and has shown a tendency to play rock fairly often (3/7 rounds). They've also played rock in 2 of the last 3 rounds. While they might anticipate me playing paper and switch to scissors (which they haven't played yet), the historical pattern suggests rock is a likely choice for them. Additionally, when I've played paper previously (rounds 1 and 6), I've won both times. Given the current score (4-3 in their favor), I need to make strategic choices to catch up.
