We do loads of touch sparring in my gym, if the other lad takes the pass and uses force rather than skill putting a little weight behind a shot to the liver normally puts them back in their place.

My coach is normally super tight on it, if some one clips you with a hard shot that can happen, correct technique and speed can often make it hard not to hit hard... if some one takes the place step it up if they are totally out of their class with you, they won't want none of it...

I always explain to the new lads you learn more boxing than you do fighting, there's a pub round the corner for that...

Only lad's wanting to compete/have competed etc get to do full contact boxing.

One things for sure, you won't learn a thing blowing inexperienced fighters out...
