Boxing Punches from a conventional right handed stance:

Introduction

The left hook can be a powerful punch delivered like a stealth bomb.  The opponent does not see the punch that hits them.  That is the punch that KO's.  The unseen punch.

The left jab is the workhorse of boxing in that it should always be in the opponents face, keeping him off balance, blinding his vision and setting him up for other punches.  Joe Louis and Larry Holmes were proponents of the left jab as a powerful punch as well as a punch to set up other punches.  Ali employed a fast stinging jab that cut and bruised the opponent's eye area.  Ali was perfection in foot movement and incredible mobility and reaction time more than the strength of his punches.  Taken together his skills were unbeatable but often unconventional.  He was always breaking the rules so to speak.  Roy Jones is an example of the same kind of fighter who was pure brilliance but age has caught up with him and fighters are able to exploit his mistakes more and more now.  Hopefully, he can hang up his gloves and concentrate on promoting the young fighters in his Stable.

The Mexican Liver Punch is a starching punch when properly landed.  Ricky Hatton used it well but Mexican fighters have perfected the punch.  Julio Cesar Chavez or Barrera come to mind.  Bernard Hopkins KO's the smaller Oscar De La Hoya with a single shot to the liver which was nothing short of a work of art.
