The leg pin pass is one of the first I learned, but the way you need to swing back and sit confuses a lot of beginners, who try to slide through awkwardly. It's therefore useful to have an alternative from the leg pin, provided once again by Paul Schreiner's Precise Pressure Passing app on Digitsu.
It begins the same way as the leg pin pass I'm used to. As you open their closed guard, slide their leg down yours and bring your knee down with it, pinning their leg with your shin. Get the cross-face, but unlike the usual leg pin, also jam your head in and underhook their other arm, locking your hands.
Swing your non-pinning leg towards the other, then drive that knee over their free leg. You should now be pinning both their thighs. From here, you can slip into mount, or if they begin to turn, flick your foot to the opposite hip first and then go to mount.
Teaching Notes: I opted to stick with the guard break I normally use, as I wasn't sure I had enough of the details for the one Schreiner does. He appears to be leaning forwards and looking down, meaning either he has a very different set of principles at work, or that's not the focus of the instructional and he's just getting to a passing position.
Anyway, in terms of the pass, I liked that this gave me another option from the leg pin. The key thing people were doing wrong is a general point rather than specific to this pass, which is leaving space when shoving that leg down. It should be acting as a ramp.
Also, pinning the leg with your shin in the middle of their upper thigh, again to take away any space: a few people were too far forward with their knee, or too far to one side. Similarly, people shouldn't be trying to get their other leg straight through as then they have no base. Instead, it needs to be out to the side for support.
