His favoured weapon at the ring proved to be a highly versatile half-hook, half-uppercut left-handed punch he called "The Smash" which accounted for the majority of his knockout wins -- it also happened to be his major downside throughout his career. Being a left-handed puncher fighting out of the orthodox stance, he didn't throw a single right hand during most knockout flurries.
