Because apparently we can't get enough threads about clinching. lol
So, a boxers clinch is slightly different from an MT clinch in that you don't have to think about knees. You have to think more about hooks and uppercuts.
what's you're preferred work in this range? push out? body shots? hooks? uc's?

...also, in boxing clinching is a rest play quite often and that's why it's not allowed to be held for too long unless stuff is happening while in the clinch, ie: shots being thrown.
