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 solution by logischer Verstand)

Logischer, if the first two moves were as you suggest: Player 'K' plays at I, followed by Player 'J' playing at H,

then 'player K' has a guaranteed win and would play it as follows:

K   J
I H
E A(forced)
C anything, with 'K' to win on next move (with either F or G)
