The knee cut from feet on hips is a fundamental guard passing technique where the top player breaks through the bottom player’s leg frames by clearing one foot off the hip and driving their knee diagonally across the bottom player’s thigh line. This pass bridges the gap between the open guard distance management phase and close-range pressure passing, converting the feet-on-hips battle into half guard or side control where the passer’s weight advantage becomes decisive. The technique rewards patience during the frame-breaking phase and explosive commitment once the cutting knee enters the gap.
The effectiveness of this pass depends on proper sequencing: establishing pants grips at the knees, systematically clearing one frame, and timing the knee cut entry before the bottom player can re-establish defensive structure or transition to a more controlling guard. Unlike the toreando pass which redirects both legs laterally, the knee cut commits the passer to a linear path through the guard, requiring crossface pressure and hip drive to prevent the bottom player from recovering position. The directional commitment makes grip fighting and frame control critical prerequisites.
This pass is particularly effective against opponents who rely heavily on feet-on-hips distance management without developing secondary guard layers such as De La Riva hooks or lasso controls. The knee cut forces a positional transition that many guard players are unprepared for, especially when combined with grip fighting that prevents the switch to spider guard or lasso guard. However, the linear commitment required means that a failed knee cut can expose the passer to guard recovery, De La Riva hook entries, or leg entanglement threats if the bottom player reads the pass early.

Playing as Attacker
Key Principles
-
Control the knees through pants grips before attempting to clear any foot from your hip to prevent uncontrolled frame re-establishment
-
Break the near-side foot off first to create the shortest path for your cutting knee to enter the gap between the legs
-
Maintain constant forward pressure throughout the entire sequence so the bottom player cannot reset their feet-on-hips frames
-
Establish crossface or collar control as the knee enters the gap to prevent the bottom player from turning into you or hip escaping away
-
Drive your cutting knee at a diagonal angle toward the bottom player’s far hip rather than straight down to maximize passing leverage
-
Keep your free leg posted wide for base during the cut to prevent sweep attempts from the bottom player’s remaining hooks
-
Commit fully once the knee enters the gap—hesitation allows frame recovery and guard transitions that are harder to overcome the second time
Execution Steps
-
Establish knee grips: Secure strong pants grips at both of the bottom player’s knees with your thumbs on the inside of the…
-
Break near-side foot off hip: Using your near-side grip, push the bottom player’s near-side knee toward the mat while stepping you…
-
Pin the cleared leg: Once the near-side foot clears your hip, immediately use your elbow, forearm, or knee to pin that le…
-
Insert cutting knee through the gap: Drive your near-side knee diagonally across the bottom player’s thigh line, aiming toward their far …
-
Establish crossface control: As your knee cuts through, release your near-side grip and establish a crossface by driving your sho…
-
Drive hips forward to complete the cut: With the crossface established and your knee across the thigh line, drive your hips forward and drop…
-
Extract trapped leg or consolidate half guard top: If your cutting leg passes cleanly through to the mat, slide to side control by sprawling your hips …
Common Mistakes
-
Attempting the knee cut without first establishing pants grips at the knees
- Consequence: Bottom player easily pushes you away with full leg extension or re-establishes frames before the knee enters the gap
- Correction: Always secure bilateral knee grips as the first action before attempting any frame breaking or cutting movement
-
Cutting the knee straight down toward the mat instead of diagonally across the thigh
- Consequence: Knee gets caught by the bottom player’s knee shield or the cutting angle lacks sufficient lateral pressure to clear the guard
- Correction: Aim the cutting knee toward the bottom player’s far hip at a 45-degree angle, sliding the shin across the upper thigh rather than driving straight down
-
Neglecting crossface control during the knee cut entry
- Consequence: Bottom player turns into the pass, inserts hooks, or frames against your shoulder to recover guard position
- Correction: Establish crossface pressure as a simultaneous action with the knee cut, driving your shoulder into their jaw to control their head position and prevent turning
Playing as Defender
Key Principles
-
Fight grips immediately when the top player reaches for your knees—preventing bilateral pants grips eliminates the foundation for the entire knee cut sequence
-
Maintain constant hip mobility and micro-adjustments to prevent the passer from settling into a stable base for the frame break
-
React to the first foot being cleared by immediately transitioning to De La Riva, closed guard, or knee shield rather than trying to re-establish the same frame
-
Use your hands and arms as secondary frames against the passer’s shoulders and hips when your foot frames are compromised
-
Keep your far-side foot active and threatening on the passer’s hip even when the near-side frame is cleared to maintain at least partial distance control
-
Create angles by walking your hips laterally away from the cutting knee to extend the distance the passer must travel to complete the pass
Recognition Cues
-
Top player secures pants grips at both knees and begins compressing your legs toward their centerline, reducing your pushing power
-
Top player shifts their weight laterally and angles their hip toward the gap between your legs, creating the line for the knee cut entry
-
Top player pushes one of your knees toward the mat while their corresponding knee drops toward the space between your legs
-
Top player releases one grip to reach for your collar or shoulder, signaling the crossface is coming as the knee cut initiates
Defensive Options
-
Re-establish foot frame on hip before knee enters gap - When: When the passer has just cleared one foot but has not yet committed their cutting knee past your thigh line—the earliest and highest-percentage defensive window
-
Insert De La Riva hook on the cutting leg as it enters the gap - When: When the passer’s knee begins crossing your thigh line but has not yet been accompanied by crossface control—hook the cutting leg before they establish upper body pressure
-
Close guard by pulling the passer forward and locking ankles as distance collapses - When: When the passer commits their weight forward during the knee cut and their hips drop close enough for you to lock your ankles behind their back
Position Integration
The knee cut from feet on hips serves as a critical bridge in the guard passing hierarchy, connecting the open guard distance management phase with the half guard and side control pressure game. It functions as a primary conversion tool in passing sequences where the top player has successfully broken the initial leg frames but has not yet achieved a complete pass. This technique integrates with the toreando pass, leg drag, and long step pass as part of a comprehensive passing system from standing or combat base against open guard. When the knee cut stalls in half guard, the passer transitions to half guard passing chains including smash pass, underhook pass, and backstep pass to complete the positional advancement.
