How you would compare this book by Mc Donald with his other works, and Nunn's Understanding Chess Move by Move. Do you like this book better by Mc Donald or the other ones are better? Thanks..

I haven't read his other books, nor the one by Nunn, but I did borrow Logical Thinking a few times from the library, and thought it was pretty good.

I am finishing Nunn now, and just got the MacDonald book.

Okay dude hoping to read your comment, I have the Nunn book too, I think it's good(though  I only read a few pages of it)..

I think they're both excellent books--as is "50 Essential Chess Lessons" by Steve Giddins. The McDonald book is aim at a slightly lower-rated player that Nunn's, although there's a lot of overlap. Any player under master-strength would profit a lot from either book.

One word of warning: These books only return the maximum value if you're willing to put out some real effort going over the games, asking yourself questions, and not being satisfied until you can answer them. No one ever got better at chess just by turning the pages

I like all of Nunn's game collections a bunch, but what Paul G said is the key. Turning the pages won't help you more than ~50pts if that. Maybe it helps with your pattern recognition a bit.

I really improved when I spent a lot of time on Soltis Pawn Structure Chess, Art of the Middle Game, and a few basic endgame books like Silman's.

I don't think I've ever really improved from studying any opening manual. Sub-2000, it's trivial to open a game and get a solid position on either side. Knowing 20 moves of the Scheveningen won't help you get better, trust me.

VERY GOOD BOOK=
