dido to keeping your lead foot on the outside. If he's insisting on staying outside he's looking to double jab and back you into his power hand. Look to counter with a jab hook and takedown, don't circle out or back straight up, good consistent push kicks will make him a little weary of stepping in if you wanna keep it rangey. Might wanna give a bit of space and set your stance maybe 30-45 degrees to your right shoulder. It feels strange but it makes a smaller target and presents a tougher angle for him to work around, he may eventually give in and settle for inside positioning or chasing you into your power side. He's gonna wanna throw lead attacks and at this angle if you give a little space it's easy to step to the outside and counter. As backwards as it may seem look to lead with your back hand. 2-3-2-, 2-1-1-2. End combos with kicks, esp to his lead leg, inside or out, it keeps his footwork and range a little off balance. Cross check his back leg when he kicks low, don't let him get comfortable with landing any 10s.
