OK, sorry about the delay.
I have great success w/ the Turtle, as I've said before. The two worst habits I had to deal w/ coming from Wrestling was my head position (great for Wrestling BAD for Submission Wrestling) which I still am working on and basing instead of flopping to the guard.
The head positioning got me choked a LOT. Now, I just get choked often! LOL! A lot of fellow wrestlers were making the transition and getting choked for giving their backs. When I started, I kind of knew what was coming, so was aware and ready for it. I did a LOT better than I thought and many guys afterwards said that they never had such a hard time getting someone's back.
So I thought, if they are having that much frustration when I know nothing about defending my back against subs, then why not make a mountain out of a molehill?
What I noticed is that if you don't allow them to get their hooks in, it is a hell of a time for them. They have to take an awkward postion w/ poor stability. Palms on the side of your neck and forearm across your jaw to block the choke and crossface respectively and you have virtually shutdown most of their options.
A good posture (elbows at hips & sealed to your ribs, thumbs on traps, palms on neck, pinky on ear, ankles flat or crossed), constantly blocking and removing the hooks, drawing them w/ intentional openings, etc. and the turtle becomes what the guard was way back in the day. The paradigm shift was that when you went to your back, the fight was over. BJJ disproved that.
Then that paradigm shifted. Then the new paradigm was if you gave your back, the fight was ova!!! Sakuraba came along in took a big steamy shit on that paradigm. Sak would intentionally give his back and used it very effectively.
Against Allen Goes, he gave his back, Goes got a FULL choke on. One of the best BJJ guys on earth had the full choke on, but because Sak did not let him get his hooks in and forced him to pick submission over position, Goes couldn't finish it.
Anyhow, my mind set, is that if things get hairy, I am OUT of there. I will actually flop to guard if I have to. I never rule out that option. I am always looking for Sit-outs, Hip Heists, etc. I have had REAL GOOD success w/ Granby variations and is my preference for escape or a reversal. If done right (retaing wrist control) and capture his leg in a cradle) you can turn the Granby into a braced (on your thigh) armbar.
Basically, w/ no hooks in they will either take a "Leapfrog" position, or be at your side similar to a "Par Terre" position, but keep in mind this is a BJJer, and not a Wrestler at your side. Not one of their strengths. So all of your usual wrestling options are there and will have a higher rate of success.
