Reset rule
Both players begin with the triangle entry already established (as if GAME-TRI-01 was just won). Reset to open triangle position when any win condition is achieved.
Top wins by
Rip the trapped arm free (arm returned past the centreline to the outside), or drive to posture sufficiently upright that the bottom player's hip angle cannot be maintained.
Bottom wins by
Achieve perpendicular hip angle (approximately 45–90 degrees off-centre) with the inside arm isolated across the body, held for five consecutive seconds.
Game Description
This game picks up exactly where GAME-TRI-01 ends. The triangle entry has been achieved — the leg is over the shoulder, the hips are elevated. The question now is whether the bottom player can complete the two remaining adjustments (hip angle and arm isolation) before the top player can escape or neutralise the position.
Hip angle and arm isolation are trained separately in DRILL-TRI-03 and DRILL-TRI-04, but under resistance both must happen simultaneously — adjusting the angle while the arm is being ripped out, or pulling the arm while the opponent drives forward to flatten the angle. This game trains that simultaneity.
How to Run This Game
Setup: Both players begin in the open triangle position: bottom player’s chosen leg is over the top player’s shoulder, hips elevated, the triangle is not yet locked. Top player’s inside arm is inside the loop (as it was in DRILL-TRI-04).
Bottom player’s objectives (simultaneous):
- Rotate hips toward the trapped arm — 45–90 degrees off-centre
- Pull the trapped arm across the centreline and hold it
- Maintain both for five consecutive seconds
Top player’s defensive tools:
- Rip the inside arm back past the centreline — retract the arm from the triangle
- Drive forward to flatten the bottom player’s hip angle
- Frame against the hips or knee to prevent the angle rotation
Scoring: Five-second hold with angle and arm isolation = bottom player scores. Arm successfully retracted past centreline = top player scores. Full posture recovery (triangle entry position lost) = top player scores.
Coaching Notes
The tension between arm isolation and hip angle adjustment is the core skill this game develops. Students who chase the arm isolation first allow the top player to flatten the hip angle; students who chase the hip angle first allow the arm to escape. The practitioner must distribute effort between both goals — not optimising either completely but maintaining both sufficiently.
The top player’s most effective counter is the arm rip combined with a forward drive: they retract the arm while stacking to prevent the bottom player from generating the hip rotation leverage needed to pull it back. Coaches should point this out to top players — the combination is more effective than either alone.
For the bottom player, the arm isolation grip matters. A wrist grip is easier to apply but easier to rip; a grip behind the elbow (controlling the arm above the elbow) is harder to rip but harder to establish quickly. Developing practitioners should learn the wrist grip first, then add the elbow grip as they advance.
Progressions
- Allow the bottom player to close the triangle and apply finish pressure once they hold the five-second position — this becomes a live triangle finish attempt.
- Add the armbar transition: if the top player postures out of the hip angle adjustment, the bottom player may pivot to the armbar (DRILL-TRI-06 territory).
- Start from closed guard — bottom player must earn the entry (GAME-TRI-01) and then convert to the angle and isolation (this game) in a continuous sequence.
