Tic-Tac-Toe: 3 In A Row

Win: If the player has two in a row, play the third to get three in a row.

Block: If the opponent has two in a row, play the third to block them.

Fork: Create an opportunity where you can win in two ways.

Block opponent?s fork:

Option 1: Create two in a row to force the opponent into defending, as long as it doesn?t result in them creating a fork or winning. For example, if ?X? has a corner, ?O? has the center, 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, block that fork.

Center: Play the center.

Opposite corner: If the opponent is in the corner, play the opposite corner.

Empty corner: Play in a corner square.

Empty side: Play in a middle square on any of the 4 sides.
