	The game of "toe-tac-tic" is a draw for two perfect players, as
the first player chooses the center and then mirrors the second player's
moves.  (The reason that I posted it is that the solution is a lot like
that of the penny puzzle).  If the first player chooses any square other
than the center, then the game is a win for the second player.
	And, yes, Marvin Gardner had thought of it first, so it isn't
unique work (even if it was original).  Thanks to:

Kim Althoff  (kima@pesnta)... For showing 2nd player win in most cases
Joe Miller   (jmil@homxb).... For correct solution and pointer to Dewey 793 *
Carl W. Lee  (lee@ukma)...... For pointer to Gardner
Karl Heuer   (kwh@bentley)... For correct solution

    * Puzzle books can be found near 793 in the Dewey Decimal System.
