The Reassess Your Chess Workbook by Jeremy Silman
Very much focused on positional training. Each problem solution has a section on evaluating and understanding the needs of the position, which was missing in other books.
I am a positional player, and have gone thru alot of videos and books. For me, this book was the most useful.
If you hit Master then your origal level of chess acuity/chess IQ was very high and absolutely could have been done without any books had you exposure to the right people (you know, like all the other people prior to 1950 pretty much did, you know the ones the ended up writing the books ... hahahaha)
Most people do not have such acuity, and no amount of booking up is going to raise their level of play.
You might be interested in Carol Dweck's work. Lots of professionals and scholars disagree with you. If anything, the reason why players like Morphy were 2300-ish is because they had, as you call it, "chess acuity," but did not have a systematized training, books, etc. The GM who trains me is dumfounded by some of missed mating patterns by players from classic games --and I don't mean games that long ago, e.g., 1950. Probably the reason why Kasparov 1988 or Carlsen 2015 could slap around the player with the most "acuity" in history, Fischer, is a product of books, supplements, training programs, more expansive opening theory (in books and databases), etc.
The thinking itself --that there are minds deterministically capable of either absorbing a kind of information or not-- is horribly troubling, and it sounds like an excuse more than it does a theory about how minds learn chess.
I simply can't entertain your assertion. There is neither empirical evidence or reason to back it.
