Also got Negreanu's Power Hold 'Em Strategy (he is my fav pro player so i went for this instead of the Harringtons to start off)
How are you finding this book?. Negreanu is my fav pro player too and i think his new book is great. I think that you made the correct choice in buying it instead of the Harringtons simply because it is more recent. The way that people play poker is constantly developing and therefore the literature has to develop along side, which i think in this case it does.
Planning on starting it soon - not really a book to take to and from work as its so big so i'll need to put aside time to start it!
Finished the Hansen book and thought it was hugely entertaing and easy to read!
