Overview

The knee-in-the-middle pass is a closed guard opening method where the passer drives their knee into the center of the opponent's guard to pry it open, then immediately transitions to a guard pass. [1] The shin splits the guard by wedging through the middle, and the passer transitions directly to a knee cut, leg drag, or other pass. One of the first closed guard openers taught to beginners.

Training Notes

One of the first closed guard openers taught to beginners. The key mechanic is using the knee as a structural wedge that the opponent's locked ankles cannot maintain closure around. Once the guard is split, the passer must immediately transition to a pass — staying in the open position without advancing allows the guard player to re-close or transition to open guard. Featured in instructionals by Bernardo Faria, Andre Galvao, and John Danaher.

Common Mistakes

!Not controlling the biceps — opponent can attack during the guard break
!Stopping after opening — must immediately transition to a pass
!Knee too high — must wedge at the tailbone level
!Not stepping back with outside foot — the step creates the splitting angle
