Say , I got a humdinger of a Jiujitsu technique for you, a real peach of a waza!
See, you start facing opponent who attempts a right sucker unch, perhaps an uppercut from the side of the leg, you sidestep to your left, his right, whilst doing a pass and check or wa uke type thingie, grasp his arm with your right kake uke arm, which passsed under the left, and strike off the back leg with an upward shooting palm shot to the side of the head with your left open hand.
Which hand then goes up the head, and comes back down with fingers hooking nder the eyebrow ridges, and making an little unbalancing circle to the rear of opponent, up around and strainght back down. Kthump!
It's all in the entry, the interception, and the kuzushi or destruction of balance.
And best of all it matches with already sharply honed skills of those on here.
Also, it can be adapted to use many other techniques with, once you efrfect the side entry and position.
