Half guard, top
Knee slice

A fast, pressure-based pass. Your knee cuts across their thigh like a blade while your upper body keeps them flat, and you slide straight through to side control.
Step by step
Pin the leg
Grip their pants at the knee, or their lapel, and keep their bottom leg flat on the mat.
Knee across the thigh
Slide your knee across their thigh toward the mat on the far side, your shin pinning their leg.
Get the underhook
Win the far-side underhook or a crossface so they can't turn into you. Keep your weight forward.
Slice through
Keep cutting the knee to the mat and free your trailing foot from their legs.
Settle in side control
Sprawl your hips back as you land and press your chest into theirs.
