If the move to the opponent's outside is done properly, the counters Kung Fu Wang and Fungus suggest will not be possible. Assuming you have moved outside the opponent's right lead:
Your right lead leg should be checking his right leg keeping him from using it.
Your right arm should be checking/grabbing his right arm/shoulder, taking it out of play.
Your left or right hand should be ready to check his left spinning elbow counter.
You should be in close contact (ideally pushing a bit against him with arm, hip and leg) to nullify most any other counter.
If I am able to get to his outside (ideally close to his back) the above conditions will be met. It is then checkmate for my opponent, providing I immediately follow up with an attack. IMO, this is the position you most want to gain. Practicing how to achieve this with various tactics is time very well spent.
