Interesting video on PL Omaha with some good commentary. How about an interview with the crown prince of PLO: Jeff Hwang. I am currently wading through his advanced books and it has made me totally re-think my approach to the game. PLO players better than me (ahem ... that would probably be 90% of PLO players ha ha) have also mentioned his books are very, very good.
