First up, let my just say that Roy is a stand up guy and great individual to hang out with, regardless of his many martial accomplishments. Can't say enough about that.
Next up, he took on the topic that we had requested, his pressure game from top, and really broke down lots of great material for us. More than just a collection of techniques, he really shared the background information and the "why" of the movements rather than just the tactics themselves.
It was a great reminder, to me, about the greatest thing in jiu jitsu. You can take a position that you've used for years, in this case we worked out of side mount quite a bit, and suddenly realize that you don't know it nearly as well as you thought you did. Then, you tack on his total relaxation during each of the movements and total eschewing of strength to make them work and you've pretty much summed up everything that is awesome about jiu jitsu. All in an hour of superb instruction.
Money and time well spent. Some post training shots:
