Analyzing the board, I checked potential threats and opportunities from both sides. While o3-mini already has three consecutive pieces in row 5, those threats are blocked by already occupied spaces. In an attempt to build a future connect‐four opportunity, I choose to start developing a horizontal sequence on the bottom row by placing an O at the far left (column 0). This move builds toward potentially connecting a horizontal line (with future moves) without giving immediate advantage to my opponent.
