I found this myself in the aincient egiption boxing archives.

"Check Hook" refers to the aincient art of combining the magnanumous fource of a perfect left hook to the chin and the unyielding power of a beam guard to the forehead. It is considered to be 100% effective in KTFO your opponent.

To this day Hatton is the only known victim to have actually managed to get back on his feet after being struck by this most awsome combination. Though he was not up for long.
