On Black Belt pressure
I have realized today that BJJ is taught in a very specific way. This is the way Grandmaster Helio Gracie apparently taught, and this is the way most, if not all, schools teach. This method apparently has success, but is it the right one? That question might be tacked another time. It's not like we have much of a choice anyway. There are reasons people get taught BJJ this way, and not any other way, probably rooted deep into Samurai tradition. Again, just because it's an old method doesn't make it the best one.
What I have realized is that you rarely get taught how to hold a position, the real nitty gritty details of a specific position. We, as BJJ practitioners, most of the times get taught isolated techniques, and the rest of the time we get taught counters. This means that we get taught the "affirmative" of a position, and not ways to STOP a certain position from happening. For example, it took me a while to learn the right moments to link the different side control transitions, but it's going to take me another five years to learn all those little details small, 140lbs technical brown belts keep to themselves, knowingly or not. Small details such as holding the opposite triceps, or grabbing the far leg from under both legs in side control. These are truths the practitioner either silently stole from someone, or discovered by himself, through laborious training. There's a reason even small brown belts have such a complete and total dominance on someone less experienced but much smaller than them. It's not really the breadth of techniques, but the finesse they developed through applying the same techniques over and over again on all types of bodies. They find the right angles, the right timing and the right "invisible" controls to totally crush people two or three times their size. And that, my friends, is good jiujitsu!
