This prevents my opponent from easily developing a horizontal sequence in the bottom row while giving me flexibility for future moves.

Playing in column 3 again would allow me to build a vertical chain and secure the center, which is usually an advantageous position in Connect Four.

First, this creates a horizontal threat pattern with my existing piece in column 2, establishing potential for a connect-four across columns 1-4 or 2-5 in future moves. By playing here, I'm also positioned adjacent to my opponent's pieces in column 3, which allows me to monitor and potentially block vertical or diagonal threats they might develop. Column 4 is centrally located, which generally provides better strategic options in Connect Four.
