Could someone point me in the direction of a video showing a moving cat stance? I don't think I follow.

not speaking for med, he might have a better example of a "moving cat stance", but this vid has some great stuff. at 2:44 paul uses a cat stance to attack while retreating back, preparing to lunge foward again. simple principles, shift back to create space to go foward anew. since the weight is more on the back leg the front leg can be used to check/kick/or set up a throw as you move your body foward again.

Eh, what video?

bahaha, my bad.

Oh, ok. in this video:

at the 58 second mark, is that still a cat stance, or do you guys call is something else?

in the vid you posted i see a cat stance at the 53 second mark. at the 58 second mark i see a cross step from cat stance into a kick then landing in a short front stance.

Paul Vunak seems to know his stuff for sure,

but why make a big point about the knife locking out (they do sometimes IMO) not being realistic - and them demo that all the way through the video?

He then goes on to 'check' the knife attack at middle range, setting himself up to be cut on the retraction everytime?

Interesting but poorly presented material IMO.

in mr vunaks defence before he checks he has already defanged the snaked by cutting the knife hand/arm of his attacker, the checking pretectects his body from the follow through of his attacker. at middle range if paul had missed the defanging move, then his opponents knife would have carried on to a vital target like the neck or torso/heart.

he covered why he uses the check at middle range as opposed to "long arm range" and how the arm is used differently at close range. that might clear some of it up, i thought the whole video was gold and im considering getting the dvd's.
