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.
