Here are a few notes on what I recall from the Glover materials now returned to the safety and sanctity of copyright.
1. Attack the same leg. When you dive for the deep half, make sure to target the same leg that you have triangled. Glover pointed this out as a major mistake that most people attack the other leg, leaving them in a weird, sprawled out on your back position.
2. Leg on the shoulder, not the arm. When you secure the leg, it should be very high up on your shoulder, between your shoulder and neck. There are a lot of reasons for this: better control, better choke avoidance. But it is another important detail.
3. Look Alike. You should not only get deep with the trapped leg on your shoulder, but you should also be looking away from the guy - or in the same direction he is looking. You don't want to be looking at him, you want to have your head turned away, with the back of your neck/head in his lap. This will also help keep you from getting brabo choked.
4. Keep the legs locked. Keep both legs squeezed tightly around the guy's trapped leg. This is especially important if you are in the middle of a sweep. You finish the sweep with the trapped leg between your legs - THEN make your move from sweep/reversal to pass.
5. Your inside hand will tend to be either on the knee or behind it. Be on the lookout for the kimura attack on your inside arm. If he comes with it, slide the hand under/behind his trapped leg to deny him access to your wrist.
6. Basic Sweep: Homer Simpson walk toward the inside. When you get his leg near his down leg, you should start to feel his weight "sit" a bit, from here reverse direction, keeping the leg trapped, and roll back over into half guard on top.
7. Inside Hook to Back Sweep: Hook the ankle with the inside hook/foot. Swim under the trapped leg with the inside hand. You will lift him backward on to his back. Be sure to keep your hands low and arms wide as you attack with the double underhook pass.
8. Outside Hook to Take the Back: Hook the ankle with the outside hook/foot. Grab the belt on his lower back with your outside hand and check the knee with the inside hand. Lift with the hook and belt hand just enough to slip your head to the back (out the backdoor). Extend your hook to create a little space. Post with your other hand to help free your other foot and swing that leg around to put the other hook in place as you move to take the back.
Building the circuitry will be critical, of course. But unlike the elusive slingshot armdrag and sweep off the shin block half guard, I'm finding myself generally comfortable with the idea of the deep half, of attacking and disrupting the base directly. The slingshot definitely needs to be part of the toolset - in a sense, the slingshot armdrag and sweep are the other side of the deep half game. But for now, I suspect I'm going to have better luck with the deep half.
