I analyzed the board and noticed that column 4 is the best spot: it already has two O pieces at row 5 and row 4. Dropping an O in column 4 will fall to row 3, stacking three vertically. This creates an immediate threat since on my next turn I could drop another piece in column 4 to complete a connect‐four, forcing my opponent to block. It also helps set up a diagonal threat, building potential for a fork. Therefore, the best move is to drop my piece in column 4.
