I notice that the opponent (X) already has two winning threats: a win in column 2 (with X already at positions (0,2) and (2,2) leaving (1,2) open) and a win along the anti-diagonal (with X at (0,2) and (1,1) leaving (2,0) open). Since I can’t block both at once, I choose the move that blocks one of these immediate winning threats. I decide to block the anti-diagonal threat by placing O at (2,0), even though X will then have an immediate win via column 2. This move at least stops one threat and might give a slim hope if the opponent were to miss their winning move. Therefore, I choose move (2,0).
