Moving in on the rear hand ,chokeing it out before any real power is expended through it.
Bit like Ricky did to Kostyas famous right hand but not just doing it with your tuff head moving in like he did!
Stop it with your front glove moving in and throw your other shot straight at his face simultaniuosly which covers the pathway of his other hand as you move away bodily from it in towards his rear arm which is stopped now or going backwards.
All in one complete movement; block, move and hit; two hands working at once while your legs take you out to freedom.
You have to time it for when he is on the right angle or create that angle yourself or at least realize it as you go through.
He will turn in further to you and be punished or back off and you chase his openings as he does, becuase in the extreme that can happen here ;you have changed his rear hand into his lead hand if he doesnt move his legs.

On the other side of the coin If someone does it to you !
The greatest escape if your not over commited is to not resist the push and remove your leg thats under the shot that has been choked out , back out underneath you ,or around behind your lead leg on a 45/ angle so that your head moves out of range of his shot and your original lead hand then comes further into range on him as you have made time and saftey margin so you can reset your leg position and stance to where he now is .
Takes practice with a partner many times to get your mind used to the reaction; doing it slow allows you to see where and when you go in and out of range and where you can utilize your shift in weight for the best reply shot.
