We hear coaches screaming at their students all the time "Pass, Pass, Pass !!!".
The guard passing game is one of the, if not the most important aspect of a solid ground game. In this video Jiu-Jitsu mega stud Jeff Glover demonstrates his "Floating Guard Pass".
Notice the keys to this pass are isolation of one of your opponent's legs, pinching the knees together, posting the hands to the mat, putting your lower body weight onto your opponent, balance, swivel and pass. Easy right?
