The Complete Williams Guard by Shawn Williams

Great stuff

I follow Shawn on his Instagram and he always produces nice tips which I use to improve my game. I've been working on clamp guard and his instructional provides seamless transitions between his guard and the clamp guard as well as numerous tips on transitioning from closed guard etc.

good breakdown

nice breakdown of the williams guard with intricate detail

good submission details

Aside from Williams guard, there's a lot of detail related to submissions, including omoplata and triangles. I like the content on reverse kimura as well. There's a ton of content, that requires time to go through. It's a similar teaching style to that of John Danaher.
