What is the name of that takedown at 1:48

[michi972]

Whizzer with inside trip. Pretty common TD choice in grappling I believe.

It looked like an Ashi-guruma using an overhook, but without a grip on the far arm, uke landed on their front.
Ashi-guruma

Ashi-guruma to front headlock, then spun around to the back. Nice little sequence for whenever a takedown doesn't land perfectly.
