Anyone who bought Nunns 's Understanding Endgames, or Understanding Middlegames? They appear promising to me, and I would like to hear if anyone have opinions?

yes, the two books are only guide to your chess knowledge but you have to practice and play more chess and in the tournament to enable you to use it. even though the books have more than 100 topics especially the Understanding Chess Middlegames, it is not a complete book because there are many phases in the middlegames that have to be study and john nunn have not yet encountered it. so, if you want to learn more, play more chess and in tournament and you will surely know by yourself what are the missing topics i been talking to. i hope it shed light to your question and the most important part is you had having fun playing chess and it gives you joy into your life. ENJOY!!!

Ehh?  

H E L L O:  Read my post again. No, you certainly didn't shed any light at all.

Your post asked for opinions on the books. He gave his opinion on the books. Good luck getting more help with that attitude 

I have not read his recent books but can speak to his lucid and intellectually rigorous style.  GM Kudrin recommended his books to me and I bought them.

Nunn is a professor of mathematics at a high-end university in England.  I would like to see him or an authority like him speak to the use of the decision making skills in other areas of life.  Too often chess players can get tunnel vision and need to broaden their perspectives outward and their abilities likewise.

If Nunn wrote "Understanding Grilled Cheese" it would probably be a great book. He is one of the best chess authors ever.

I agree with the previous poster: If Nunn wrote the operating instructions for a chain saw, I would probably by one--and I don't have any trees!

The Endgame book is an excellent presentation of what Nunn believes to be the 100 essential topics in the endgame. The examples seem well-chosen, and Nunn's explanations are clear and complete. Anyone who works through the examples in this book will greatly improve their endgame play, as well as enjoying the almost magical nature of some chess endgames

The Middlegame book is a bit different, because middlegames are by nature more complicated and varied than endings, middlegame knowledge can't be neatly systematized. What Nunn has done is take a series of important topics and used grandmaster games to illustrate his themes. I think there is a treasure trove on knowledge to be gained from this book, but it does demand attention and hard work if you're going to get the benefit. So be warned! But if you're eager to do the work, you will get a lot out of the book,

There is not much money in book writing like Nunn's; the late Christopher Hitchens spoke to this in one of his CSpan appearances even with books written with almost universal interest.

Are articles by Nunn in chess publications available online?  Does he have a Facebook page?

Are you blind? He didn't say a thing about the books. I didn't ask for advice on how to improve my chess. I asked about the content. 

OK, any adults out there, who can read? 

:) Brilliant! Thanks!

Thanks to those of you who understood the original post. 

My impression of the books are that they are amazing; a brilliant man, thoroughly written and neatly presented. I havn't bought them yet, but I will.

You specifically asked for opinions. You did not clarify whether you wanted  relevant advice or not via their knowlege of the book, or that it was strictly content driven opinions that you were seeking. Try reading your own post again Einstein. If someone has nicely taken the time to regard your thread, whether or not it was helpful, with best interests in mind, be grateful loser.

Hijak, I will never be greatful just because someone write something back. I will always assume that the poster actually has something substantial to say.

I was VERY clear in my original post that I want feedback on the books. Not about how to improve my chess, or advice on how many games to play. 

Don't defend idiotic posts, man. 

Alright, lets see what happens if we try to switch the subject (a 2nd time; first from the actual books, and now from the attention span of mr Hijak and mr pido9catchy):

Would you folks generally agree what most GMs seem to claim: that learning the endgame thoroughly is the best way of increasing your playing strength? I.e., studing a good book on the endgame is better than studying  openings or the middlegame; lets assume that we are talking about some average club player. 

Please only respond if you understood the question.

Yes you should play more chess man, it helps.
