The Inside Trip is a great take down that when hit right will floor your opponent and remove any possibility of scrambling out.
Why?
Because you will land inside their guard, so it is very difficult for the bottom person to scramble when you are between their hips. While it might be the highest scoring position, if you are dealing with a feisty person that is hard to keep down, landing in the guard is ideal to secure top position.
The Russian 2 on 1 is a great position to hit it from, as you will be able to remove their arm completely out of the way – giving you a clear path to hit your inside trip.
