Professor Lucas Lepri explains how to prevent knee on belly and escape from side control to open guard. The situation begins with the opponent holding Lucas in side control position and Lucas framing and defending against the mount with his knees. In this scenario the opponent maintains shoulder pressure while attempting to establish the knee on belly position, so Lucas reacts by turning away and off-balancing the opponent. If the opponent does not post, Lucas can roll him and reverse the situation. If the opponent posts and attempts to pull Lucas back to side control, Lucas uses the momentum and pushes him away, creating enough space to square his hips to the opponent and recover an open guard.
