Thanks Bauerndiplom, I was out and only today I could read your reply. My interest in this book is not bullet wich I do not like, but only to see if the advice on openings is similar to the "Blitz Theory" book wich is about blitz technique and see if both give the same advice about openings wich I see now is not the case. It´s interesting to hear the advice of playing what we know, because in the other book "Blitz Theory", there are openings wich are very good only for blitz weapons but some of them are very good in slow chess too and I think the best advice is a compromise between what we know better and the better openings weapons for blitz or bullet because a very complicated opening that we like in slow chess could not be the best pratical weapon in blitz or bullet. 
I found the blitz openings advice more interesting then the bullet book, because in my view playing 1.h4, 1...f6 Kf7, 1.e3 2.d3 3.g3 4.b3 and putting the bishops in fianchetto and knights to follow like Usain Bolt or 1.f3 Kf2 a la Fischer could be a bullet way of playing but not a great way to improve one chess. 

Yes, I saw him playing bullet and blitz several times, and playing several moves like 1...g6 or 1...b6 etc, but I am curious to see if his advice for amateurs or for internet players is the same of what he plays or if is advice is diferent because this book is not about Nakamura itself but an explanation of bullet techniques and advice.

Anyone has this book? There is a chapter about choosing your openings for bullet chess and I am curious about what openings are because I divide my openings for slow chess and for blitz and I am curious to know what Nakamura choose for bullet to see if his choices are the same openings I select for blitz.
