I've been whinging and griping for a while that I have a hard time remembering specific techniques and that I wished for more rules-based grappling. In other words, I'll forget the technique but with basic principles, I can reverse-engineer the technique according to the needs of the specific situation.
I know it probably gets old, but I'll encourage you again to check out Cane Prevost's blog The Gentle Art. Just a good solid breakdown of all the basics, from a rules standpoint. Reverse engineering heaven! :) For example, the 3 P model of teaching jiu jitsu... Posture, Pressure, Possibilities.
A little treat-- Stephan Kesting's 10 minute private on finishing the RNC. Really worth your time if you haven't seen it.
On my way to open mat now.
