Some people will defend the triangle by wrapping their trapped arm around their opponent's leg. This will leave the defender open to the omoplata.
In this sequence, we will use this defense to set up for the top spin. It must be done quickly before your opponent can trap a leg or sit up and block your back.
Here is a vid of the technique with the step by step below:
Brett Starts to Lock a triangle on Eddie
Eddie Postures up
Eddie wraps his left arm around Brett's left leg - this gives Eddie a little breathing room as well as serving as a bait for the Omoplata
Brett takes the bait, and goes for the Omoplata
Eddie acts quickly, before Brett can sit up and block his back or grab Eddie's leg- Eddie posts his right hand on the ground and quickly moves his legs over Brett's head
Having saved his arm from the omoplata and clearing Brett's legs, Eddie secures his side control
