The bottom position in a Mixed Martial Arts fight or a
Jujitsu/Grappling match. The fighter performing
the guard position is on their back with the attacking fighter between their legs. From this position, the guard fighter will try to prevent the fighter on top from attacking, tightly locking their legs behind the attacking
fighter's back. The fighter performing the guard attempts to neutral the movement of the fighter on top in order to either escape the bottom position or to perform a submission from guard to win the match. A fighter can end up in guard position by either being taken down, being reversed, or purposely pulling their opponent into the guard in order to get the fight to the ground.
Example:
At Pride Fighting Championships' Pride Shockwave 2006, Japanese Mixed Martial Artist and Jujitsu Black Belt,
Shinya Aoki, submitted Norwegian Mixed Martial Artist Joachim Hansen with a
gogoplata choke from his guard.
