Strategy:

A player can play a perfect game of tic-tac-toe (to win or, at least, draw) if they choose the first available move from the following list, each turn.

Win: If the player has two in a row, they can place a third to get three in a row.
Block: If the opponent has two in a row, the player must play the third themselves to block the opponent.
Fork: Create an opportunity where the player has two threats to win (two non-blocked lines of 2).

Blocking an opponent's fork:

Option 1: The player should create two in a row to force the opponent into defending, as long as it doesn't result in them creating a fork. For example, if "X" has a corner, "O" has the centre, and "X" has the opposite corner as well, "O" must not play a corner in order to win. (Playing a corner in this scenario creates a fork for "X" to win.)

Option 2: If there is a configuration where the opponent can fork, the player should block that fork.

Center: A player marks the center. (If it is the first move of the game, playing on a corner gives "O" more opportunities to make a mistake and may therefore be the better choice; however, it makes no difference between perfect players.)

Opposite corner: If the opponent is in the corner, the player plays the opposite corner.
Empty corner: The player plays in a corner square.
Empty side: The player plays in a middle square on any of the 4 sides.
