I'll be honest, grappler. For many years, I've taunted the clock choke as a "bogus move." And, the clock choke doesn't like being teased that way, but, it's a Jiu Jitsu technique, so it has no real way of defending itself.
Why do I call out the clock choke, you ask? Well, it because hardly anyone I know can get this finish in action and, even in practice, it can be hard to catch properly. Yeah, Wallid once tapped Royce to it in competition, but that means very little. The question is - can you tap dudes using it and, if so, how often?
The truth is, my beef is not with the clock choke. It's just an innocent technique that no one seems to apply properly. It's actually a solid choke to hit when your opponent's in turtle position. With that, I leave you with a proper breakdown demo'd by GB black belt and MMA figher, Alberto Crane.
Watch, practice and attempt frequently. And, if you roll with me, try it and I'll give you a cool $100 if you can catch me with it (never happen).
