In this video I show an alternate technique for when your opponent is not giving you the underhook in Half Guard. This is not a common technique and I would rate it as medium percentage. I've had a lot of success with it throughout the years but it does take good space management, the ability to flatten your partner out with your body and great balance on the other side as your knees will be momentarily together. The fear is that you get bridged over in the transition of bringing your knee over to the floor on the other side. If you know this is a a danger and you adjust your base accordingly you can have a lot of success with this move. I would highly recommend repping this move out before trying it during live movement so that you can better understand the spacing.
