There is a big dichotomy in the field of Brazilian Jiu-Jitsu. On one hand – there are the sport BJJ specific techniques. On the other side, there are self-defense techniques. And there is potentially a big difference between the two. At first and foremost, the fact of the matter is that Brazilian Jiu-Jitsu is a martial art. And this means that there are many techniques that you can apply in a real fight, aside from the sports mats.
To be fair, there are many BJJ techniques that may be very useful in a street fight. The rear-naked choke, the armbar, the triangle, the leg lock – all of these basic BJJ techniques can work with devastating effectiveness. However, Heelhooks in street altercations has often been debated. In this video we can see a case of heel hook in a street fight incident
Remember, don’t fight in the street, compete in Jiu-Jitsu. You should only fight back to defend yourself or if you have no other choice.
