Punching in the clinch, popularly known as "dirty boxing," is one of the distinctive features of modern bare-knuckle boxing. The regulations of the Bare Knuckle Fighting Championship are as follows: 1. Punches are the only permitted blows and must be delivered with a closed hand (no kicks, elbows, knees or grappling). 2. Elbows are legal as long as they do not connect with the head or body. 3. Kicks to the legs are allowed. 4. No biting, eye gouging or hair pulling. In traditional boxing, punches are delivered with the hands open, but there is no rule against closing them for protection. A boxer can also use his fists while in close range if he chooses to punch at his opponent. Closing the distance between you and your opponent is very important in any fight, but it is vital in bare-knuckle boxing because there are no rules prohibiting contact. You can punch with either hand, but it is best to use the same one for throwing and receiving punches since there are no defenses like a glove to protect your hand. As long as you don't break the rules, you can do whatever style of fighting you want within the boundaries of common sense. Kicking with bare feet is difficult so most boxers prefer to punch from a distance. That being said, there are some elite bare-knuckle fighters who know how to deliver powerful hooks and uppercuts with their closed fists.
