I'm choosing column 2 because it allows me to build upon my existing O piece, creating a vertical pair. This is a good strategic move as it starts developing a vertical threat while maintaining presence in the center of the board, which typically offers more connection opportunities. Playing in columns 3 or 4 would stack on opponent's pieces, potentially giving them an advantage. Columns 0, 1, 5, and 6 are reasonable alternatives, but column 2 gives me the best structure toward building a winning position.
