Is this the Master Class he did?
I didn't pay for his class specifically, but if you pay, you get access to the whole series, and it's pretty cheap. In addition to poker, you can learn a lot more (cooking, music composition, writing, etc)
I've only watched the first 3 or so videos. He explains things very well, IMO. But the concepts have been pretty standard since, well, it's just the first 3 videos
But having said that, I think he illustrates the importance of position better than I've ever seen. If he does that well on other concepts, it should be a very good series.
