I'm choosing column 1 for several strategic reasons. This move starts building a new potential horizontal sequence from the left side of the board. By placing my piece here, I'm working towards creating multiple winning threats rather than just extending my existing line (which is blocked on both ends by X pieces). This position doesn't give my opponent any immediate advantage, and it keeps my options open for future plays. It also prevents my opponent from potentially using this column to create a strong position later. Column 1 gives me the most flexibility while working towards creating multiple threatening lines.
