Thinking of this subject i decide to go search for a video of the best left hook iv ever seen....Sugar Ray Robinson vs. Carmen Basilio....you guys remember that? Unfortunately i couldn't locate it now, i have it at home il check it out later, but i saw a few vids of Robinson and he threw the hook palm down a lot, but also threw it palm in.

Another left hook that i recalled was the one in the final round between Oscar Bona vena and Muhammad Ali. Ali elivered that hook palm in althouh it connected on the blindside of the screen.
