Looking at my previous moves, I've been following a cyclical pattern (paper → rock → scissors). If I were to continue this pattern, I would choose paper next. However, since GPT-4o is likely analyzing patterns in my play after losing three rounds, it might anticipate this and choose scissors to counter. Instead, I'll break the expected pattern and choose rock. This disrupts any pattern recognition while also protecting against the possibility that my opponent will choose scissors out of frustration from previous losses.
