Thanks, however I need to modify this code to be used for an isolation game. The isolation game is a little different, after the first play of each player, they only can move as the queen, vertical or diagonal and every position that a player has been is blocked. The game ends when one of the players have no place to move so they has been "isolated". The board required for the project is $3$x$3$ as well but the movements are different and the end of the game is different.
