I'm choosing column 1 because it will create a horizontal line of three O pieces (in positions 1-2-3 at the bottom row). This sets up a potential winning opportunity where my opponent would need to defend both column 0 and column 4 to prevent me from completing four in a row. Additionally, this move builds my offensive position without giving my opponent any immediate advantage. While column 4 would block my opponent's vertical progress, it would also place my piece directly above their pieces, potentially setting them up for future diagonal opportunities.
