I need to block the opponent's immediate win by placing my X at position 0,1. The opponent already has Os at 0,0 and 0,2, so they would win in the next move if I don't block the top row. Additionally, this move creates a potential winning opportunity for me in the middle column, as I already have an X at 1,1. This gives me a two-way attack setup - I can potentially win either via the middle column or by creating another threat on my next move.
