Fighters who used their head prefer ot snuck it under their opponent's chin to hide and smother,some sneaked a suspicious amount of head clashes with their opponents. But are there any boxers who just rammed their head into the opponents chest,take out their breath and starts mauling in?
I don't know about the chest directly, but Hammerin Hank definitely kept his head in the opponents shoulders, pushing them back ,keeping them off balance, and not able to get any real leverage on their punches.
