The Art of Positional Play by Samuel Reshevsky

This is one of the first chess books I read and I highly recommend. It goes through major positional themes, how they arise and are exploited.

Take your time with each game until you understand it. It's easy to read through games and miss the lesson.

Another book like this one: "The most instructive games of chess ever played" by Chernev.

Positional chess is important but so are tactics. They go hand in hand. The tactical training on this site is pretty good ...

"Just because a book contains lots of information that you don’t know, it doesn’t necessarily mean that it will be extremely helpful in making you better at this point in your chess development." - Dan Heisman (2001)

You might want to look at some instructive game collections, such as Simple Attacking Plans by Fred Wilson (2012),

Logical Chess: Move by Move by Irving Chernev (1957),

and/or The Most Instructive Games of Chess Ever Played by Irving Chernev.

I have never heard of a download being available for the Reshevsky book. McKay sells it. Maybe check their site.

Fred Reinfeld died more than a decade before the publication of The Art of Positional Play. I suppose it is possible that a Fred Reinfeld manuscript remained unpublished during all that time. Perhaps weehunt112 can check to see if the Reshevsky book contains discussion of games after 1964. There would have been some practical difficulties if Fred Reinfeld had attempted to write such discussion. On the other hand, I see no reason to doubt the assertion that Fred Reinfeld ghost-wrote the earlier Reshevsky book, sometimes known as Reshevsky's Best Games of Chess.

On another subject, around here, there has often been praise for Simple Chess by Michael Stean, another book about positional ideas.

The book is generally not that complicated. Each chapter deals with a specific topic like Space, King Safety, Open Lines, Passed Pawns and then gives game examples.

I'm guessing if you want to improve, you'll need to understand those topics anyway so "The Art of Positional Play" is as good as any for that purpose. To get the most out of it, might want to make sure you understand the basic plusses and minuses of each major topic before moving on to the next.

Many of the game analysis, maybe all, were redo's of Reshevsky's USCF magazine articles. I'm guessing even though Reinfeld may have had some part. The notes on Reshevsky's own games at least had to have exclusive or near exclusive Sammy input.

If you are talking about articles written after 1964, Reinfeld involvement would have been difficult.
