I choose to place my 'X' on the opposite corner (2,2). With 'X' already occupying the center (1,1) and your 'O' in the top left (0,0), an opposite corner move is classically strong in Tic-Tac-Toe. This move sets up potential fork opportunities where I could create dual threats on subsequent moves, pushing for a fast win if you aren’t able to block both threats.
