What a fascinating question. I hate Tic-Tac-Toe for the very reason that it is impossible to win if whoever starts first knows how to win and it's impossible NOT to draw if both player know how to win.
But I gotta agree with the above post. A more important deciding factor is skill and foresight.
To those who think chess is a draw with best play:
-If you remove one of Black's pawns, do you think it's still a draw or is it now won for White? How much of an advantage does White need for a theoretical win?
To those who think chess is a theoretical win for White or Black:
-With best play, how many moves do you estimate it takes to checkmate?
Note that I'm NOT asking if chess itself is a theoretical win, draw, or loss for White. We all know that's been brought up enough times on the forum.
