If executed correctly, the aggressive boxer will lunge in and sail harmlessly past his opponent like a bull missing a matador.

This is rarely seen in professional boxing as it requires a great disparity in skill level to execute.

Ricky Hatton was caught with the check hook as he was lunging in; Hatton continued forward as he was knocked off balance and proceeded to ram his head into the ring post as Floyd Mayweather stepped out of harm's way.

2) The Backstep Check Hook First of all, this variation is deemed risky as the boxer might end up in front of the opponent, exposing himself to their attacks.

Instead of pivoting off to the side, a step backward is taken with the rear leg thereby enabling him to get out of the way of their punches while landing the check hook.
