Porra might be blasphemy posting a gi question here, but jokes aside I'm having problems with some better guys putting their thumb in my collar and keeping their base. On the off chance that I do get a perfect electric clinch and finish the sweep about 70-80%, he'll swim his free leg over my arm which in Nogi WOULD set me up perfect for the vaporizer, but again the handles bail him out and let him keep top position. A situatsh occurred today where he was stuck there for a good minute, then wised up and gripped my pant to get his knee out of the lockdown and lead right into a no hand pass. Any advice or experiences with doing electric chairs in the gi would be greatly appreciated. Respec towards the system, no-gi devouts, I ain't trying to hate. I'm just trying to elevate my game and looking for any help I can get. I referenced Advanced rubber guard today and got a nice review of basic principles, but am open to any experiences with having success in the gi.
