Just an idea.
This may or may not help in the golf,
but is good to know anyway.
If you take this magic square:
2 9 4
7 5 3
6 1 8
and play tic-tac-toe on it,
you have three in a row iff you have three different
cells so that the sum of their three numbers is 15.
Source of the idea:
Csákány Béla, Diszkrét matematikai játékok.
1998, Polygon, Szeged
Update: changed 1 in 1st row to 2. Thanks to jdhawke and also QM for noticing the typo.
Update: this one does not check for valid moves so it's easy to cheat.
Also, it does not detect ties yet.
