There would also be "A First Book of Morphy", by Frisco Del Rosario: dozens of commented Morphy games, through which the 30 principles of the game according to Reuben Fine are illustrated (10 of the opening, 10 of the middlegame, 10 of the endgame) . It's a precious book, I always have it at hand, it's what I use.
I would suggest that you continue your present approach.
A brief History of the State of the Art:
Start with the older masters, such as Anderssen and Morphy (1850s). They formalized the proper methods of play in open games (King safety, center control, development, tempo, etc).
In the late 1800s, Steinitz discovered the best methods of play in closed or semi-blocked positions. At about the same time (or a bit later) Tarrasch worked out the principles of space control; and combining this with the earlier work by the other masters he created a highly dogmatic school of "chess determinism". This was a big help to the development of the game, but many talented players and chess theorists found Tarrasch's rigid formalism to be stifling.
The reaction was not long in coming... younger players like Reti (whose game against Bogoljubov I gave above), Nimzovich and Breyer led a "Hypermodern Revolution" against Tarrasch's extremes of formalism, and emphasized dynamism and counter-play as a counter-balance to the static elements which Tarrasch had valued so highly.
As usual, the "Revolution" went too far and over-shot their goals, but a later generation of younger players (Alekhine might be the best example) took the best of both worlds, static and dynamic, and chess strategy became less theoretical and dogmatic and more concrete.
... then Botvinnik and his "Scientific School" came along, and chess became a much more difficult game...
Thank you for this summary, and for the advice.
If I understand what you suggest, a good method can be to progressively learn the various aspects of the game, from the simplest to the most complex, following its historical evolution through the games of the Masters : therefore, first master the principles of the open game (through Morphy and Anderssen), then approach those of the closed game (Steinitz), then the remote control of the center ( right ? ) with Nimzovich, and so on.
If so, it would be the most satisfactory method possible for me. A very long road, but I'm not in a hurry, and I have no goals to achieve other than to try to increase my understanding of chess, as far I can.

Reti was never a world champion, but he had a reputation as a artist at the chess board.
His final move in the game against Bogoljubov in New York 1924 was one of the most elegant mating combinations of all time.
I actually sighed with pleasure at the end there. I kid you not

The middle game was a joy to play over for me.
Reti's dismantling of Black's over-extended center is a classic demonstration.

I will go back and play it through. I did rush to the ending today. Thanks for posting it.
Another tip -
If you are looking for games by some little-known player (for example, I mentioned Gyula Breyer as one of the originators of the Hypermodern School), one way to find the game scores - not annotated, unfortunately - is this:
Go to the free internet chess games database 365chess.com. You don't even need to register an account. Click on "Search", then "Chess Games" to reach a search engine. Put in the name of the player (in this case "Breyer, Gyula"), make sure the Ignore Colors box is ticked, and hit "Search".
That will bring up every game on record played by that person.
Games from the late-middle of a player's career might be most typical... by then his style would be fully developed, but he wouldn't yet be declining from advanced age.
Sadly, Breyer died quite young (his whole recorded chess career spans less than a dozen years), so his career was cut short and games from late in his career might be most typical of his style.
I enjoy playing games where you really have to think e be very precise, sometimes with sacrifial ideas, those are better than playing a game where you won because of a blunder, it feels like your opponet could do so much more, but for a lack of atention, not a lack of quality, you won.

I love endgames. When there is enough time to play them meticulously ( otherwise unwatchable things come out. Thrilling, maybe, but poor quality )

Thank you again !

As one who has not tried working through master games, where would you suggest a novice (myself) begin with Morphy's games? Thank you.
Lichess offers free access to a collection of seven annotated games by Paul Morphy.
