Just like that
Glimmerscape has a nice article on Kokyu-ho (breath exercise, or breath throw) from katate-dori (one-handed wrist grab). The concept of misdirection in Aikido is one that is easy to understand, but incredibly hard to put into practice. Atemi are used a lot to distract the uke and break their posture, but the sort of subtle misdirection demonstrated in the photos that accompany the article requires a great deal of skill and practice.
