I'm choosing column 3 because it places my piece in a central position, which generally offers more opportunities for connecting four pieces in multiple directions. By placing here, I'm also directly above one of my opponent's pieces, which disrupts their potential for a vertical win in this column. This position also has potential for setting up diagonal connections with my pieces at columns 0, 2, and 5 in future moves. While there's no immediate threat to block or win to create, this central position gives me the most strategic flexibility for future plays.
