I noticed the promising diagonal with my O’s at (5,5), (4,4) and (3,3). If I can eventually get an O at (2,2), that would complete a diagonal connect‐4. By playing in column 2 now, I’ll drop my piece into row 3 (since row 5 is X and row 4 is O), thereby filling the gap so that the next O dropped in column 2 will land at row 2—the perfect spot to complete the diagonal. This move forces my opponent to block in column 2 on their next turn, giving me a strategic advantage. I’ll play in column 2.
