Long time reader, first time poster. I got in a street fight with a more experienced guy then me a couple months ago. He proceeded to grab my left shoulder with his left hand and block my right hand/shoulder from punching him. I proceeded to do the same. Anyway the fight finish and I was pretty banged up. I just wanted to know if you guys know any techniques to counter the part where he blocks my right shoulder from punching him or getting around it once he has the grip.
