The RDLR back step sweep is triggered by the passer’s reaction to RDLR guard. When the passer attempts to exit RDLR by stepping their captured leg backward — the classic back step pass response — the bottom player reads this motion and converts it into a sweep to side control. The passer’s withdrawal creates a base imbalance that the bottom player exploits.
RDLR is designed to threaten two things simultaneously: the back take inversion (berimbolo) and the back step sweep. An opponent who drives forward gives up the back take; an opponent who steps back gives up the sweep. This two-threat structure is why RDLR is a high-value position — neither reaction is safe for the passer.
The sweep itself is relatively simple mechanically: the bottom player follows the passer’s stepping leg with their own body, uses the RDLR hook and shin grip to control the retreating leg, and as the passer’s weight shifts backward, sweeps them to the side. The difficulty is in reading when to commit — moving too early looks the same as moving too late from outside the position.
INV-G01Invariant "The bottom player must maintain their feet between or at the line of the top player's knees. Losing this line allows the top player to advance without engaging the guard."
Why it works hereThe passer's back step is an attempt to take their knee out of the bottom player's foot line and reset outside the RDLR hook. The sweep weaponises that attempt: as the captured leg withdraws, the passer's weight is briefly committed rearward over a single base, and the bottom player follows the leg to keep contact within the foot line until the passer falls. Sweeping early — before the line is actually being broken — fires into a balanced passer with both knees still in range.
See full invariant page → The RDLR sweep uses the passer’s back step — an attempt to exit the foot line — against them. When the passer steps backward, their captured leg’s knee is moving away from the bottom player’s control zone. The bottom player’s response is to follow the leg and convert the backward momentum into a lateral sweep before the passer can reestablish their base outside the RDLR control range. The back step is the passer’s attempt to break the foot line; the sweep is the bottom player’s conversion of that attempt into an attack.
Established RDLR: inside hook on the near leg, shin grip, bottom player on their side. The passer is circling or attempting to pass. When the passer begins the back step motion — the captured leg stepping backward to exit the hook — the sweep is triggered. This is a reactive entry: the sweep opportunity appears only when the back step is initiated, not before.
