Essentials of Stroke

Illustrator Insider Training: Rethinking the Essentials is the first installment in a series of courses designed to show experienced Illustrator users to how master core features and build art more efficiently. Adobe Illustrator has evolved dramatically over the years, and many creative professionals may be missing out on features that have been added to the latest versions. This course takes a fresh approach to core concepts, such as paths, attributes, object hierarchy, groups, and layers. Advanced techniques such as combining multiple effects and customizing textures are also included. Exercise files and a free worksheet are included with the course.

This is possibly one of the best coaching videos I've seen on snooker. It adopts a more modern approach to the art of coaching. Excellent coverage on essentials such as the Stance, Grip, Cue Action, etc. It further analyzes the Grip in detail, showing exactly what the fingers do in relation to the cue action, i.e. relax, tighten, etc.
