def fourth_turn

  if win_two

    else

        block_two

#block _two either executes or goes into the next_move method, which finds an optimal move. If optimal_move executes, it calls another user_turn, which in turn calls fifth_turn as the computer still has not yet won in its fourth_turn to continue the game. This continues until the last turn, fifth_turn, in which the computer either wins or it's Cat's Game.

    end
