KNEE SHIELD TO BACK TAKE

The knee shield to back take is the half-guard transitional technique in which the bottom player uses the knee-shield framing to off-balance the top player forward, then climbs around to the back when the top player overcommits to a passing direction. The technique is one of the highest-percentage back-take entries in modern half-guard play and was refined by Lucas Leite and the broader half-guard offensive community in the 2010s.

The entry begins from an established knee-shield half guard with the bottom player on their side, knee wedged across the top player's chest, underhook secured on the trapped-leg side. When the top player attempts to clear the knee shield by walking around it, the bottom player extends the knee-shield leg sharply to push the top player forward and upward, simultaneously pulling with the underhook to rotate the top player's body. As the top player's torso rotates, the bottom player swings their outside leg over the top player's shoulder or hooks the inside of their thigh, transitioning into a back-control configuration.

The technique exploits the fundamental tension in half-guard top: the top player must clear the knee shield to pass, but clearing the knee shield exposes them to the back-take if the bottom player has won the underhook battle. Lachlan Giles' no-gi half-guard system features this transition extensively, and Gordon Ryan has used variations of it in ADCC competition. Defensively the technique is countered by maintaining the underhook battle from above (the top player's underhook neutralizes the bottom player's), by stuffing the knee shield rather than walking around it, or by transitioning to the leg-drag pass before the back-take can develop.
