Recently I started sparring. In boxing, the athlete who jabs is told to keep right hand tucked at right side of face (pictures below). Just curious, why the right hand isn't taught to be more in front of the face, tucked below the eyes ready to block or catch/parry the punch? Is there a reason its traditionally taught to keep at side? I seemed to have little more luck in front, as its hard to throw a long hook to left side.
Pictures below where face is more open to punches, etc
