A) Mastering Opening Strategy (Hellsten) B) Mastering Chess Strategy (Hellsten) C) Understanding Chess Move by Move (Nunn) D) Understanding Chess Middlegames (Nunn) E) Boost you Chess: Beyond The Basics 2 (Yusupov) F) Chess Strategy for Club Players (Grooten) G) Attacking Chess for Club Players (Grooten) H) Chess Structures (Flores Rios) I) Improve your Chess Pattern Recognition (Oudeweetering) J) Complete Manual of Positional Chess (Sakaev & Landa) K) Positional Chess Handbook (Gelfer) I'm thinking C) looks like it's first. Any insight into any of the books appreciated. Or any sites to find out? Tim. Please rank these Middlegame books in order of strength.

None of these books have great value. The better ones are:

E) Boost you Chess: Beyond The Basics 2 (Yusupov)
C) Understanding Chess Move by Move (Nunn)
D) Understanding Chess Middlegames (Nunn)

I can only comment on a few:

F) Chess Strategy for Club Players (Grooten) : This book has excellent examples and detailed explanations. I’d say that if Pachman’s Modern Chess Strategy is barely comprehensible because it is too concise for you, this book would be perfect. I’d say it is good for USCF rating 1200-1900 and perfect for 1200-1700. Higher rating’s would find some new things in it but may find the explanations are too wordy. This is the only one of the group I can rate that is a real MG strategy book like Pachman’s.

H) Chess Structures (Flores Rios): This is OK for all ratings for what it is. It’s not really a book to study from but more like a dictonary of standard late opening positions and resulting MG plans. So a starting point. To study you’d need to look up a lot of examples, preferably annotated examples. The sections would make great flaskh cards.

I) Improve your Chess Pattern Recognition (Oudeweetering) : I have this and have only looked at a few chapters. It is lots of new ideas (one disconnected idea per chapter) for me (USCF 2000’s). I would study better from it if it had a lot more examples of lists of games for each topic.

K) Positional Chess Handbook (Gelfer) : I’ve worked thru this whole book. It is a collection of late middle game / early endgame strategic themes with lots of examples. I needed a physical board because the printing was typical Dover tiny diagrams. I’d say that if you are often losing games in late MG’s at whatever rating then you will find things here to study based on your last mis-played late MG.
