Game Over / Z-Lock — Defending
Defending Game Over and the Z-lock in no-gi — three live finishes from one position. Deny the second leg, hide the heel, and understand why the name is a claim.

The game over position from underneath — a Z-lock structure where the attacker has your leg controlled at both the knee line and the hip, and can attack either heel depending on which of your legs they have.
The name is a claim about the read rather than the mechanics. It is called game over because a defender who arrives here has usually already lost the exchange two positions ago, and what remains is choosing how it ends.
It threatens both heel hooks and the Z-lock itself. Defending against three finishes from one position is why the differential here is the same as the saddle.
Elevated RiskGame Over / Z-Lock (Defending) is an elevated risk technique. Both heel hooks are available, so the knee is exposed to rotation in either direction, and the Z-lock adds a hip attack on top. Loading arrives without warning movement because the structure fixes the leg before anything is applied. Serious injury can occur Immediate once the heel is reached. The presence of three finishing options means the attacker does not need the one you are defending..
If you are new to this technique: read this section before anything else. Understanding the danger is part of understanding the technique.
The person applying the technique is responsible for releasing immediately.
