Open Guard

From OTMWiki

The open guard is typically utilized to perform various joint locks and chokeholds. The legs can be used to move the opponent, and to create leverage. The legs open allows the opponent to stand up or try to pass the guard, so this position is often used temporarily to set up sweeps or other techniques. Open guard is also a general term that encompasses a large number of guard positions where the legs are used to push, wrap or hook the opponent without locking the ankles together around them.
