Hmmm... it depends on his approach. If he's more Muay Thai than TKD then you're gonna have to rely on your MT skills. If he decides to get more TKD on your ass then you are gonna have to be wary of a couple of factors. Remember to watch out for that axe kick, he can mess you up big time if he catches ya with that one. Unless he loads up that side kick with some pre emptive footwork then you are not really gonna have much of a problem dealing with it. Just watch his footwork, and hopefully you have been working on your boxing because most TKD and MT people don't seem to be able to use it singly. ( I'm not ragging on anybody, I'm a MT guy and Kyokushin guy myself.) Close the gap and keep pressure on him, you might want to spend the first round being cautious and getting a taste of what he does. Good luck and I hope that you kick his ass.
