I'm selecting position (2,0) for two key reasons:

1. Defense: My opponent has X pieces at (1,1) and (2,2), creating a potential diagonal winning threat through (0,0)-(1,1)-(2,2). Though I already have an O at (0,0) blocking this particular diagonal, I need to be mindful of fork opportunities.

2. Offense: By placing my O at (2,0), I'm building a potential winning line in the left column. I already have an O at (0,0), and after this move, I'll need just one more at (1,0) to win.

Additionally, taking (2,0) prevents my opponent from creating a potential fork situation. If I had chosen a different move, my opponent could potentially create multiple winning threats that would be impossible to defend against simultaneously.
