Also known as: Knee-Elbow Escape · Shrimp Escape (mount) · Elbow Escape
The technical mount escape: frames at the hip, a shrimp to one side, and a knee sliding through the gap — trading mount for half guard, then half guard for guard.
Escape · Gi & No-gi · Difficulty 2/5 · Usually learned at White belt
Starts from Mount as the bottom player → lands in Half Guard.
The details that make it work
Elbow wedges inside their knee; shrimp onto your side to make a gap at one hip.
Slide your knee through the gap and hook their leg — you are in half guard the moment the knee passes.
Chain it: the upa threat makes them post wide, which opens exactly this lane.
Where it goes wrong
Trying to force the knee through while flat on your back with no shrimp.
How opponents counter it
Grapevine the legs before the shrimp
Float to technical mount as they turn
