The combatant on top will try to untangle the leg and pass to obtain side control or mount, while the bottom combatant will try to transition into a full guard or alternatively attempt a sweep or submission.

The lockdown (known in judo as niju garami)[1] is a variant of half guard where the defending practitioner further intertwines the legs to achieve a figure four.

Using the more extended of their legs, the practitioner traps and drives the foot of the opponent upward; thereby attempting to limit the ability of the opponent to pass to full mount or side control.

Z guard - also known as the 93 guard is a position where the practitioner locks his feet together and clamps down on the opponents thigh while using their top leg knee to exert pressure into the opponents hip.

The Z-guard is a must for any practitioner as it creates a strong barrier between you and your opponent with the top knee controlling that distance while there is a push pull effect happening with the bottom leg.
