I have watched some poker training videos of Ace Poker Solutions on NLHE in Youtube which are really so much effective for the newbies in poker. See the videos of RIO also. These videos will help you to improve your skill in poker.

I really like James Hudson videos. All essential, great commentary, pretty easy to understand. He makes NLHE videos.

Thank you

DjuNKeLL and Steve Paul are pretty good for NLHE.
