Is this kind of like a sidekick...where you fake a Teep/front-kick and turn it into a Sidekick? If yes, then this does work well vs. MT from my experience. It's very annoying. Only downside is that my nuts are wide open for accidents when they throw inside leg kicks. The general Sidekick also works well vs. MT, very annoying but both doesn't seem to do much damage usually. I've been Sidekick to the throat a few times, and that hurts but didn't stop the fight. This is why I pressure fight with hands a lot vs. Karatekas, K-F, etc. because they like to keep distance w/sidekicks.
What's Northern Gong Fu like? I've sparred mostly with these guys: http://www.dennisbrownshaolin.com/I also find, in general, the fighting techniques of northern Gong Fu styles and Muay Thai to compliment each other nicely.
The Black dude (Boxer), is Arthur Williams (or something)...and held 2 Boxing world titles and had a high win/KO record too. He was a little out of his prime in that video....but many Boxers seems to be very arrogant and thinks that they can beat up Kickers easily w/o needing to train how to address kicks. Although they only enter K-1 when they're out of their prime, can no longer get fights in Boxing and mostly, need the money. And K-1 loves bringing them in b/c it's a spectacle and sells tickets.your video is a prime example of what happens to people who have never dealt with powerful leg kicks before. I'm sure that boxer was very tough, but people who aren't used to those types of leg kicks simply can't handle them...
