In this YouTube video by Martial Arts Books And Videos From Turtle Press, Master Sang H. Kim presents 6 scenarios and the self defense techniques to use in each of them. There are counters for hair grabs, frontal choking, collar grabs, belt grabs, front shoulder grabs, and rear shoulder grabs.
Practice these carefully with a partner. A rule of thumb in martial arts training is to practice a technique slowly, until you have it just right. You can work on speed later.
