Essentials

Photo neededWe only show photos that have been checked for accuracy. This position doesn’t have one yet.

Half guard with your top knee across their chest or hip as a shield. The shin keeps them at distance so they can’t flatten you, and it opens sweeps and leg entries.

Your goals
  • Keep the shin across their body as a frame
  • Control their far arm or collar
  • Off-balance them toward the shield
What they want
  • Pass the knee by flattening it or backstepping
  • Crossface you over the top
Key principles
  • The shield is a frame, not a wall: keep moving
  • Pair it with an arm grip
Common mistakes
  • Letting the knee drift low so they stack over it
  • Shielding without any upper body grip
