I have lately been coming across much boasting by the Brazilian Jujitsu practioners about their grappling techniques and claims that no martial art would stand a chance once you are on the ground how ever there must be more than one Aikido technique which if applied in that second the Brazilian Jujitsu fighter reaches with his hand to grab would neutralize the whole attack so what is it in your opinion?
How about a Kimura lock? Worked for Kimura.
Or if they pull guard, picking them up and slamming them on the back of their head? Remember we aren't on a cushy mat or relatively cushy canvas. Worked for the dude on The Ultimate Fighter 5 (also known as The Most Immature Show Ever 5).
Basically, anything that their sporting/entertianment environment outlaws: strikes to the throat, back of the head, breaking fingers, clawing eyes, testicles, etc. Using weapons..
