Julian Gardner is a decent no limit tournament player and anything he had to say about poker i would certainly listen too, i wouldnt pay £65-£100 for the privilege though.
Padraig Parkinson is much less successful and somewhat of a gibbering fool whenever he commentates on uk poker shows on tv and hardly ever says anything that he doesnt find immensely funny.
Scott Gray i have no idea about but i just hope he is not Scott Gray the author as that particular fellow writes about science fiction and chemistry.
Jesse May of course is well known in the uk as the voice of poker on this side of the pond albeit sometimes bungling his way through the odd commentary, and when he hooks up with Padraig Parkinson you sometimes have to wonder if they are even talking about poker.
Jesse May's current book list has a highest price of £6.59 so a jump of between 10-15 that seems incredible to say the least.
I also dont think Julian W Gardner the author is the same person as Julian Gardner the poker player. I could of course be absolutely wrong on all counts here but something just doesnt sit right here at all.
