Re: What technique would you apply to neutralize Brazilian Jujitsu attacker
I regularly use it, and it is a big part of my game. Like anything else, it takes lots of practice. Plus one needs to be pretty familiar with all the positions that it connects too. Bravo's book does a very good job of explaining how rubber guard-half guard-butterfly all work together. I don't use butterfly much, but I transition from rubber to half freely.
Rubber guard, x-guard, de la Riva, all of Marcello's new stuff with platas...BJJ, or rather submission grappling, is very much a constantly growing and evolving thing.
