Taking the power out of your opponents pins – getting under hooks: It's never any getting pinned by a good top player. Not only is it hard to move – sometimes it's hard even to – and a skilled opponent is constantly threatening to convert the pin into a submission hold. You can take way much of the power of your opponents side pins by consistently pommelling your under and inside his into under hooks. This greatly undermines his connection to your torso and allows you turn onto your side rather than flat on your back. This immediately takes pressure off the diaphragm and helps you breath more easily. It also allows much easier movement towards position and/or getting up to your knees to escape the pin. In addition it greatly reduces the immediate danger of most of the standard from this position. It doesn't take much to get that under hook in, but the rewards are great. Next you're suffering under a smothering side pin, rather than just try to bulldoze your way out, work to get both your arms under his first. Then get on to your side and you'll find that everything from breathing to movement to escapes become significantly easier and less risky.
