Freeman,
All models noted as plus size are plus size to the best of my knowledge.
Modena,
I figured it was something like that.
McClure,
does it work on only beginers, yes by itself it only works on beginers. HOwever when you start using the pressure to force the grounded op. to switch to hips or over committ then it tends to open some other things such as leg over the top passes.
The easiest thing to do to defend the pressure to reach cross side and cup the back of the elbow then pull forward and down. This normally will force his weight forward with it and takes the elbow off the inside of the leg. THis opens up a pretty simple arm drag sweep if you can break his posture at the same time. If you can move the arm with just one of yours, think about going two on one with a kimura grip and drive it back then pull forward again.
The most common transition out of the inside leg pressure postion is to look to push one of his elbows back opening a triangle but most people feel that coming.
What I do is look them in the face and ask "do you know any other guard passes cause that one hurts and isn't going to get you anywhere" if they don't take the hint I then bite them
If this makes sense to you fine, if not I can try to give you some other options just ask.
MoM,
ass that fine is always appreciated here.
