Re: Nikyo Basics
Do shomenuchi ikkyo as Erick and others suggested, then slide the hand controlling the elbow down to the wrist, then front pivot bring the hand up, circling with the blade hand of your hand not controlling the wrist...their hand should drop into your 'tiger's mouth', the space between your thumb and the rest of your fingers. Make sure your grip with that hand controls their thumb. This is one basic variation...shoulders should be back and down to "close" the spine, elbows just slightly bent, and apply the control with your hips without leaning forward.
There are many other basics and variations...the goose neck control is ususally not considered a basic from what I've seen...more of an applied come along standing control.
