[{"move": "1,1", "player": "claude 3.7 sonnet (low2)", "reasoning": "I'm choosing the center position (1,1) for my first move because it's strategically the strongest opening in Tic-Tac-Toe.

First, this continues my diagonal from the center (1,1), setting up a potential winning diagonal from top-left to bottom-right. Second, playing in a corner maximizes my future winning opportunities as it opens pathways to win through either the bottom row or the right column.
