I'm analyzing the board: my pieces are at (5,2) and (5,3) in the bottom row. By placing an O in column 1, it lands in row 5 and creates a horizontal line of three O’s in row 5 (columns 1, 2, and 3). This sets up a double threat: I can win on my next turn by dropping an O in either column 0 (to complete O’s in columns 0-3) or column 4 (to complete O’s in columns 1-4). My opponent can only block one of these threats, ensuring my win. Therefore, column 1 is the best move to force a win.
