Who played first? (Posted on 2004-05-07) Difficulty: 3 of 5
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.)

(In reply to Sum it Up by Scott)

Therefore, first move: O, North.

X's response: South? No because O will in effect go Middle and force a win.


That's not so; after O plays middle (center) X can play southeast, and the game is a draw.
