Is it a hard cover?
How to study chess?

Is it a book by Nunn or a rework of the classic Chernev?
Does it explain every single move?
I don't know, you tell me what the problem is.
What is the title of the book? Maybe that book is advance for you. Try Logical Chess Move by Move by Chernev.

So it's a rework of the classic Chernev book by Nunn. I wasn't sure.
It explains every single move of the games and Nunn worked hard to bring it up to date and make it more accurate.
Why do I have to explain this FOR the poster? And what is the poster's complaint?
It sounds like a great book for beginners.
If he doesn't understand this book then what will he understand?

Understanding Chess Move by Move is harder to digest for a beginner. It also has ocean lines of variation. Logical by Chernev is easier for a beginner. After the Chernev book, reading that Nunn book is a good step.

Lol. Si lo stupid doliera you would vivir in a grito.
The words are supposed to analyze the position for you, and you should learn from the thought process or analysis the author is giving you.

I red Understanding Chess move by Move and it is one of the biggest trashes I've seen in all my life. Tons of variations just to tell me something that could have been said with 3 words.

He is reading the very same old Chernev book, revised by Nunn. And complaining about it, for some inexplicable reason.

If you dont like words and like to figure out things by yourself and probably learn nothing look at Bronstein books, they are great for beginners.

Maybe he is looking for a more overall general guide at opening,endgames,tactics and strategy. A good alternative for the Chernev book are Idiot's Guide to Chess by GM Wolf or Winning Chess Strategy for Kid by Coackley.
Rather than suggesting the Chernev book, I usually suggest Idiot's Guide to Chess or Winning Chess Strategy for Kids Coackley as first chess book for beginner. These books show the general breakdown of opening,tactics,endgames and strategy. They are easier read than the Logical Chernev book,

I was reading a book, then I was confused, I said "How this words going to improve my game?, maybe the next day I will forget all, and I'll keep playing the same like yesterday" So I stopped of reading, now I have this question
How to study this game?, Maybe there are several things I need to know before read again to get the best improvement, to get everything a book can offer.
I should analyze every position before the explication? or there are more things.
