In round 1, I chose scissors and my opponent chose paper, which led to my win. My opponent (Claude 3.7 Sonnet) is likely to anticipate that I might stick with scissors since it worked for me before, or switch to paper thinking I might choose rock. To counter this, I'll choose rock for round 2. If my opponent switches to paper expecting my rock, they would win, but I think there's a good chance they'll choose scissors to counter my potential paper choice, in which case my rock would win. Additionally, Claude may try to break a pattern that gave them a loss, making scissors a reasonable prediction for their move.
