Wilson Reis back take from half guard

This is a somewhat advanced movement from Wilson Reis.

It begins in the deep half guard position (top) and is a pretty excellent unorthodox attack that gives you the back.

As the skill level of competitors goes up, the value of taking the back also goes up as well. I believe it is the position with the most amount of leverage that is the most difficult to defend against, and is fought for so fiercely because of this.
