I analyzed the board and noticed that row 5 already hosts two O pieces at columns 3 and 4. By dropping a piece in column 5, I add a third consecutive O horizontally on row 5. This sets up a direct threat because my next move could be to drop in column 6 to complete a four‐in-a-row. It forces my opponent to block on column 6, giving me a strong strategic advantage. Therefore, I choose column 5.
