Play over Master games. Especially the old masters, before the computer age... since their games will be easier to understand.
How do you improve your positional play?

Reti is another of the old masters with a beautiful, lucid positional style.
Richard Reti vs Efim Bogoljubov (1924) Richard VIII (chessgames.com)

Indian Kama Sutra Chess have many good positions.
Study and practice of it will improve the play indeed.

It will be worth your while. I would think I only have about three books which use Algebra.
Reti's is a great book, indeed.

I like old books.
Indeed. I find the older stuff from the pre-computer age to be the best.
If I had to pick ONE chess book to study, it would be "Pawn Power in Chess", written by Hans Kmoch and first published back in 1959.

His terminology and explanations are a bit turgid for me.
But already excellent players find it great, si have come to the conclusion it is a book for very advanced players who are trying to get answers to questions they cannot answer.

I watch commented classical games from books or from video courses here https://chessmood.com/course/chess-classical-games
@blueemu for what rating would you recommend pawn power in chess? I'm just finishing Amateur's Mind which I was comfortable with. Was either going to move straight on to Reassess or insert an inbetween read. I'm 1400-1500 on here.

I read it back when I was around 1700 and enjoyed it immensely. I had to read it twice more before I felt that I had absorbed it properly.
The book does NOT hold your hand! It is for knuckle-dragging, hairy-backed MEN, not for the faint of heart.
If I wanted to improve my tactical play, I could just do chess.com puzzles or puzzle rush. But with positional play, how can I improve that?
