How do you always win at tic tac toe?

Against a perfect opponent the best you can get is a draw, but if you start in a corner and the opponent slips, you can build a double threat they cannot block.

Who goes first in tic tac toe?

Usually the player with X goes first. Starting is an advantage, so it is fair to alternate who opens between games.
