Foundations Stage 4 — Guard Passing Study Guide

Stage 4 of the foundations curriculum teaches the student how to pass guard. This study guide explains why passing follows retention in the curriculum order and how the four introductory passes fit into the broader passing systems.

Why passing comes after guard retention

A student who has learned guard retention first already knows what a passer is up against. They have felt the frames, the hooks, the angles they need to break. Teaching them to pass at this stage is teaching them to solve a problem they already understand from the other side.

The reverse ordering would be worse. A student who learned to pass before learning to retain would be taught to “pass a guard” that is mechanically inert — because they would not know what a competent guard feels like.

The four foundation passes

Stage 4 introduces four passes — one from each major passing family:

Knee-cut pass — the representative knee-slice pass. Cuts across the opponent’s guard with the knee as the wedge.
Over-under pass — a smash pass variant. Closes distance and uses compression to remove the guard player’s hooks.
Double-under pass — both underhooks on the hips, stacking the guard player’s hips toward their head.
Smash pass — from half guard bottom’s perspective, the pass that flattens and settles into a pin.

These four cover enough of the passing-systems spectrum that the student has a toolkit to deploy against different guard types. At developing level, the developing focus blocks will expand this into complete passing systems.

The invariables that drive passing

Passing is a structure-and-angle game more than a power game. The invariables that load here:

INV-02 (structural alignment) — passing requires the passer’s structure to be better than the guard player’s. A bent-over passer loses to a well-framed guard.
INV-05 (angle) — passing is finding the angle from which the guard cannot defend. Smashing into frames does not pass guard; angling around them does.
INV-07 (level change) — most passes involve a level change to remove the guard player’s hip engagement.

The guard passing objectives concept page covers what the passer is trying to achieve in the range.

The pass-to-pin chain

A pass is not complete when the legs are cleared — it is complete when the passer has established a pin (side control, knee-on-belly, mount, or north-south) and the guard player cannot recover immediately. Stage 4 treats the pass and the pin-establishment as a single chain, not two separate skills.

This is an application of INV-08 (position → control → submission). The pass gets past the legs; the control is the pin; the submission comes later (stage 6). A student who celebrates “passing guard” before the pin is established will lose the position on every third rep.

Common errors

Muscling into frames. Passing is angle-based. Driving into a good frame just produces stalemate.
Passing without pin. Getting the legs cleared and stopping there. The pass is not done until the pin is established.
No weight. Passing requires the passer’s weight to be on the guard player. Passes attempted from the knees, with weight on the passer’s own base, are low-percentage.
Forcing one pass. Foundations-level students often commit to a pass the guard defends well and keep grinding. Pass-chaining (e.g. knee-cut to smash when the first fails) is developing-level but worth introducing as a habit at this stage.

Drilling progression

Cooperative. Each pass drilled to pattern-lock, 20 reps each side. Partner gives the guard that invites the pass.
Specific resistance. Start in open guard, passer attempts knee-cut; guard player retains. Then cycle to each of the four passes.
Live. Pass/retain sparring. 2-minute rounds. Restart on pass or sweep.

Completion criteria

Before moving to stage 5, the student must:

Complete each of the four passes with pin establishment against a resistant partner at least 30% of the time.
Transition between at least two passes when the first is defended.
Maintain a side-control pin against a resistant partner for 30 seconds.
Recognise which pass is appropriate for which guard (knee-cut for open guards with legs extended; smash/over-under for half-guard and butterfly).

Next: stage 5 — back position.
