This one, for example,
shows combination from a pin (kesa gatame) to a triangle choke (san kaku jime).
I will tell you the the background noise of people playing basketball in the same gym is pretty darn annoying but this is made up for by the facts that
- It is one of the few judo videos that uses the phrase "equilateral triangle",
- It includes a gratuitous arm bar.
I recommend going to watch this video and just stay on the channel. It will play numerous videos on matwork one after the other. If you like judo, grappling, mixed martial arts or matwork in any form, you'll thank me for referring you here.
