I'm choosing column 1 because it creates a strong horizontal threat. By placing my piece here, I'll have three O's in a row (in columns 1, 2, and 3), which forces my opponent to block at either column 0 or column 4 on their next turn. This gives me the initiative and creates a clear threat pattern. While placing in column 4 was also considered, it wouldn't create as strong a connected sequence since my opponent already has a piece in column 4. This move gives me the best opportunity to build toward a win while limiting my opponent's attacking options.
