You are correct, I'm suprised to see how many people think it's the hook, cross etc... the straight right hand or as some call it "overhand" is the most powerful punch, obviously the straight left if your a southpaw, just watch the Franklin - Quarry fight and you see that Rich knocks him out with the straight left punch. Many one punch KO's are done with the straight punch (overhand) it's the one punch where your arm is at full extension meaning all your power is at the very end, if you have the right gap your opponent is in full one hell of a ride.
