During his time in Miami, Florida, Andreas Resch visited the Freddy Trillo academy on several occasions to train some Brazilian Jiu-Jitsu. Freddy is a black belt under Tom Deblass who owns an outstanding academy called the Trillo Academy. If you're ever in Miami, check it out!
Freddy shows a great setup for the rear-naked choke in this video. Use it to submit Andreas if you ever meet him.
Andreas also choked out an alligator but that's not a big deal... he got lucky.
