book suggestion

first book has a review here, I still need the pdf of it.

https://www.chess.com/article/view/book-review-chess-tactics-for-champions

and someone analyzed all the games in the book "The Most Instructive Games of Chess Ever Played" here. So I can just use this thread instead of having the book, you think?

Edit: Found them both thanks.

It's important to work on the areas you're weakest in. "Chess Exam and Training Guide" by Igor Khmelnitsky is a great book for doing that, and more. Through a series of problem positions that you try to solve, you end up with an estimated rating in 12 areas, including tactics, calculation, positional play, strategy, openings, endgames, and others that I can't recall. For each area, resources for study are recommended. 

The book has 79% 5-star and 19% 4-star ratings on Amazon. It's not an easy book...it takes work to do your best on all of the positions. But it's worth the effort if you're willing to work seriously to improve your chess. 

I second this recommendation!

thanks to all

"Logical chess move by move" OK

thought it was the same book, since the author is same. These will keep me busy for quite a while I guess. It's hard to choose books since there are too many and all look promising.

thanks for the assist, again
