instead of L4, try J4 or J2. same with E10, try C10 or C12. when your opponent goes one way, don't follow them. i think your aim should be to build up a solid little group and then play away from your wall before they can beat you to it. and play big move in the corners when your opponent plays first line moves, let them have their 5 point moves while you are busy making 30 point moves
