The game of reverse Tic-Tac-Toe, called Eot-Cat-Cit

[Alkatran]

Since the program always beats you, it's correct.

But this isn't about always being beaten, this about choosing one strategy that ALWAYS works for NOT being beaten!

This program will tell you the answer to "Can Someone Win at the game?"

The program uses the move search algorithm already described to play eot-cat-cit against you as player 1 and win every time. Have you run the program to verify this?

It's a pretty good bet that if the program can do perfect play, its win-testing functions are correct.

Perhaps I haven't been making myself clear: the updated version not only plays eot-cat-cit to itself to find a winner, it actually beats you as a human player, where it makes a move then you make a move and so on.
