The optimal move here is to play at the bottom-right corner (2,2). This creates a diagonal line with my existing X pieces at (0,0) and (1,1). By placing my X at (2,2), I'll form a diagonal from top-left to bottom-right, creating an immediate winning condition. The opponent's O pieces at (0,2) and (2,0) don't currently threaten to win, so I can focus on completing my own winning pattern rather than blocking.
