Given this tic-tac-toe position, as played by two expert players, who went first and where? Also, which was the last "move"?

 X | O | O 
---+---+---
   |   | X
---+---+---
   | X | O

(An expert player is a player who would never play in such a way that would allow his opponent to win, and who would also try to get the possible best result.)

O went first in the top middle square, X then went in the middle right square, then O in the top right, X in the top left, O in the bottom right, and finally X in the middle bottom.
Put simply, the first move: O in the top middle square.
The last: X in the bottom middle square.
