It seems like it's been a Gojushiho kind of couple weeks! This week's Waza Wednesday takes a look at the opening of Gojushiho, as practiced in the Shorinkan, but other versions of this kata have similar movements. In this case, the morote-gedan-barai (double low sweep) is used to pull the attacker into a strike, and set up the armbar, which is performed with the following osae-uke/uraken-uchi (pressing receiver/backfist strike). We demonstrate against a punch, but as always, the specific attack is less important than the positioning, points of contact, and direction of movement.
*And yes, I completely forgot to make the key points clips black and white the way I usually do :P
