Simple AI

Is there a simple way to figure out a way to find out which turf in a list is the closest item there is without taking diagonal steps? I want to create an AI which would step to a cardinal line from an opponent.

Diagram:
Legend:     @ = Opponent
                % = monster
                + = cardinal directions (rook view)

          +
          +  
          +   
++++++++++@++++++++++++
          +          
          +             
   %      +            
          +     
          +     
          +


Basically, I want % to step three tiles up so it hits the imaginary line.

Just check the x/y co-ordinates for the various mobs, and then move the mob accordingly. Eg.

  %  |
     |

Monster is at (3,5,1) and Player is at (6,3,1)
With the x-values, 3-6 = -3, or just 3 for distance.
With the y-values, 5-3 = 2
After this, just check the distance between the two results, and them move the monster accordingly. So we would make the monster move south in this to get it in a cardinal line from the player.
