I'm selecting column 1 because it would start building a potential diagonal threat. If I play in column 1, it creates the possibility for a diagonal connection from bottom-left to top-right (if I can later play in columns 0, 2, and 3 at the right heights). It also begins developing the left side of the board where I don't currently have any pieces. However, I must note that based on my analysis, the opponent (X) has already won with a vertical connect four in column 3.
