I’ve uploaded two more excerpts from my soon-to-be-released Dynamic Half Guard DVD to Youtube and Google Video. You can check them out at
Preview 1: How to counter your opponent’s attempt to block a backclimb attack. You can watch it below, or at Youtube (www.youtube.com/watch?v=UP5ODwPbP1g)
Preview 2: How to secure the Kimura armlock from half guard when your opponent grips his shorts or gi pants. Again you can watch this clip below, or at Youtube (www.youtube.com/watch?v=rdVWyYb61IM)
P.S. The Dynamic Half Guard DVD has more than 100 techniques, drills and variations and is available on this site.
