@dsmith42 can't agree more. And the biggest issue I, personally, have a bone to pick with is the space issue. Nimzowitch wrote an article titled "Is Dr. Tarrasch's Die Moderne Schachpartie Really A Modern Conception of the Game?", and in that article he gave this:
"Heading the 'inadequate' defenses to the Spanish this time is Steinitz' line ... d7-d6(?) - the question mark originates with Dr. Tarrasch - with or without ...a7-a6. After:
Dr. Tarrasch gives preference to White's game because of his 'freer play', which can be used for all manner of possible attacking continuations.
If Dr. Tarrasch did not conclude from purely external features of the position, such as the 'freer game', the internal value of the position, which in reality depends only on the specific situation in the center, he would never give preference to white's game"
Nimzowitch then proceeds to explain how black can pressure white's center from all sides, causing white to be on the defensive - even though it is white, not black, who has more space, more activity, and a pawn center. Almost like magic, like an art - which it kind of is. You can do the same in all kinds of positions when you have less space - like in the french defense, for example, it is possible to "make it work" despite the "bad bishop" and "lack of space", as people who haven't actually played the defense say.
Drives me mad to no end.
What was valuable in Nimzowitsch has long ago been absorbed into the chess mainstream. And what has proven less useful has been discarded. In fact, in most grandmaster games today we see the Italian game, Ruy Lopez, Queens Gambit declined and Slavs where all the play is based on classical principles. The Hypermoderns enriched and broadened our understanding of chess, but the built on the foundation created by Steinitz, Tarrasch, et al. Of course Steinitz, Tarrasch and Lasker all played the French defense with great skill
Nimzowitsch was absorbed into the mainstream of the Soviet School, but far less so elsewhere. Petrosian played entirely based upon Nimzowitsch's principles, for example, Fischer not so much. It's been a while since we've had a Russian or ex-Soviet World Champion, and the hypermodern influence at the highest levels has waned during the whole of that span.
The reliance on engine analysis has pushed the chess world even further away from the hypermodern school. The classical rules are more easily quantified, and so many play to an engine's analysis number without understanding how that number is arrived at.
The hypermodern was never fully absorbed into the mainstream of chess, except perhaps for Alekhine and Petrosian. There are fundamental conflicts between the classical and the hypermodern which were never really resolved over the board, and remain unknown to this day.
