Learn to Attack From Closed Guard
Quick fire video showing 38 attacking combos from closed guard in 4 minutes. Learn to switch from one attack to another, or transition from a sweep attempt into a submission. Lots of great combos for when your opponent blocks your submission, you can immediately switch to another. I loved the guillotine to triangle combo. Also the armbar to omoplata, this is available a lot against low ranked opponents. The Triangle to Omoplata is great if someone has snuck a speedy hand inside your triangle giving them space to resist for a long time, just switch to the omoplata.
