i really enjoyed his checkmate and his tactic book.
John Nunn's "Understanding Chess Middlegames"
I looked into the book and decided it's a bit over my level. I will probably buy it if my OTB rating is over 1500. But it's seems very good, could just be a little frustrating right now.

I have the book, and it's very good, but not for lazy people! His examples are non-trivial, and you have to be prepared to do a bit of work if you're going to get the most out of the book. It's not a great book for casual skimming, but you can learn a lot if you put in the work.
Thank you. I would know if it's a good book from people that also have it. I will put a lot of effort to understand and assimilate all the material in this book.
Just to clarify: I am a lazy person! And I would pick up the book, glance a particular topic, and then put the book down again. Finally I had to face the fact that this wasn't a book for casual browsing--at least not at my level.
then how did you get a 2300 rating?

I've got both the endgame and middlegame books, and I'd like to echo the comment about working at it.
I bought the endgame book first and dipped in and out of it. Whilst I think Nunn's writing is superb, I don't think I got the full value from it, due to my approach.
The middlegame book is equally well written, and aims to break the notion that the middlegame should be played by employing rules of thumb that we would have picked up during our chess careers.
Instead he states that you should look at the whole board as one interconnected and fluid thing, and that you should plan your moves accordingly. He then goes on to show a number of common positions from recent games, and explains how one should think about each example. You get the most from this by playing through the positions (I do this using pc vs scid), and looking at the (mercifully) few variations on offer.
The writing is brilliant, and the explanations clear. Once I've finished this I'll be revisiting the endgame book using the same method mentioned above. I've recently taken a break from chess, and Nunn's middlegame book has rekindled my interest completely.
In terms of audience, I feel that anyone 1200+ can get a lot of great information from this book, though it can't be read passively: you need to play the games through to get your money's worth.
OP: I hope you're enjoying it too!

I will look into this book.
I have Nunn's "understanding chess move by move" and I really like it.
You do need to put in the work though. To analyse one game from the book above it takes me around 3 hours. There are 30 games so it's 90 hours worth, and only for the first reading.
Chess books have an amazing money/usage time ratio.
Nunn's book is a more in-depth counterpart to a good strategic middlegame explanations book.
If you've read How to Reassess Your Chess, or My System, or Chess Strategy for Club Players, or the newer Naroditsky book, or the Pachman books, this would be a good practical follow up.
Those are all high-intermediate books to begin with, though. And I'm quite sure I haven't got all I can out of them, so the Nunn would just be intellectual wanking for me. Kind of like Art of Attack, which I'm proud to own, but shames me when I realize I haven't exactly mastered all the material in How to Beat Your Dad at Chess just yet.

Hi, I bought John Nunn's "Understanding Chess Middlegames",
do you think it's a good book to study midgames? I also have other 2 Nunn's books and I find that Nunn is a very good writer, but what do you think of this book?
Excuse me I posted in the wrong section
