Yes thank you!
Notation in the Road to Chess Mastery by Max Euwe

The important thing to keep in mind is that the moves are notated from the point of view of each person doing the moving: White or Black. The files are named after the piece that originates on that file in the starting setup. Other than King or Queen (which is obvious), there is the King's Bishop, Queen's Bishop, King's Knight and Queen's Knight and so on. Many books started switching from "Kt" to "N" since the King also starts with K.
Here is some old English Descriptive:
1. P-K4 P-K4 2. N-KB3 N-QB3 3. B-B4 B-B4 4. P-QN4 BxP* 5. P-B3** B-R4
And Now the same in Algebraic Notation:
1. e4 e5 2. Nf3 Nc6 3. Bc4 Bc5 4. b4 Bxb4 5. c3 Ba5
* 4. BxP is clear that it's taking the pawn on b4, since if he took the pawn on f2, it would be written "BXP+"
** There is no need to specify KBP or QBP moving to B3 since the Knight on f3 makes that pawn unmovable.
What a confusing mess. It gets worse if you have dyslexia.
I started reading the book to learn more about opening theory in the nimzo-indian, but I can't understand any of the notation. What do things like P-Q4 and N-KB3 mean in the context of pieces and squares? I included a screenshot of a page in the pdf if it helps
