Many BJJ practitioners have made a career out of forcing an underhook from half guard and using it to sweep or take the back. This is a staple approach for many elite-level grapplers, including Lucas Leite, Bernardo Faria, Tom DeBlass, and others. Their success demonstrates how powerful the underhook can be in dictating the pace of a match, turning what seems like a defensive position into a dominant one.

The underhook in half guard is a game-changer, but it’s not without its counters. While securing an underhook from bottom can open up a world of offensive opportunities, experienced opponents know how to neutralize it. Whether by smashing your position, flattening you out, or threatening submissions like the Darce choke, a skilled top player won’t let you take control so easily. This is why mastering not only the setup but also the reactions to counters is crucial for anyone who wants to play an effective half guard game.

SBG’s Matt Thornton is known for his ability to break down these high-level details in a way that makes them accessible and practical for grapplers of all levels. In this case, he shares key insights into making your half guard truly elite—providing adjustments that can make it virtually unpassable. By applying these details, you can stay safe from pressure and submissions while maintaining control, allowing you to effectively sweep, attack, or transition to a superior position.
