Kihon Kata Sequence 9

	Kihon Kata Sequence 9: gedan barai through 90 degrees oi tsuki		Tori threatens with a fist or finger. Trouble is imminent and it is time to be proactive.
			The most general function of a reaction hand is to grab and pull. Here uke grabs and pulls, blindsiding tori.
			This naturally sets up an oi tsuki.
			Often a good attack is a rapid succession of strikes to the same area. The reaction hand still does work, taking hold of whatever is available (in this case a shirt): pulling to increase the impact of the blow, unbalancing to keep tori from attacking, and exposing vital areas.
