I'm choosing column 1 for two strategic reasons. First, it blocks a potential threat where my opponent could build a horizontal line starting from positions (2,5) and (3,5). By placing my piece in column 1, I prevent them from getting 3 in a row horizontally, which would put pressure on me to block column 0. Second, this move starts building my own potential winning pattern on the bottom row, giving me more options for future moves while limiting my opponent's development.
