What
This technique is one of the fundamental fighting strategies (Mae Mai) of Muay Korat. The core idea behind this move is that by stopping the attack at its power source, even a very powerful swing punch can be easily stopped.
Why
Muay Korat swing punch is a trademark of this style: it is a fierce attack that packs a lot of power, when properly executed. By striking the shoulder, the defender can stop the attack before it is completed thus making it easy to defend.
How
When the opponent starts to turn his body in order to strike, the Korat Boxer steps forward and throws a straight punch to the shoulder. The straight punch blocks the momentum of the opponent’s attack and, if executed with enough force, can even dislocate the attacker’s shoulder.
