I’m playing offensively. I notice that row 3 already has two O’s in columns 3 and 4. By playing in column 2, my piece will drop to row 3 (since rows 5 and 4 are occupied in that column) and form three consecutive O’s (at columns 2, 3, and 4). This creates an immediate horizontal threat—if I get to play next, I can win by completing the connect four with a piece in column 5. This forces my opponent to block my winning move, thereby giving me a strong advantage. Therefore, I choose column 2.
