The Myth About Chess Tactics and Solving Chess Puzzles

Agreed!

Tactical vision is very important--especially because it reinforces another fundamental skill, namely calculation.

But strategy is just as important. If you focus purely on tactics, you'll eventually run into diminishing returns, because your positions will suck and you won't get the opportunity to deliver your beloved tactical blows.
"Unfortunately, they’re not smart enough (yet!), to show positional or strategic mistakes, such as when you weaken a pawn, make a bad exchange, choose the wrong plan, or make a decision that may be right but isn’t practical."

I think this is overstated. The engines do show these things, it doesn't explain why, but it does show positional and strategic mistakes. Like in your first example it immediately gives +0.6 for Nde2 and -0.2 for the 2nd best move Nxc6.

Also if you use the threat button or play through a few moves many times you can often figure out the why as well, eg. you can see the engine is suggesting Rb8 for black making the point about the open b file obvious .
I have become kind of oversensitive to over-used meme images. And this is definitely in my top 5 of 'if I see this image I really don't care about the message'.
Solving puzzles has helped me a lot. I love it when the a pattern I have solved repeats in a game.
I also suggest my students to solve as many puzzles as possible. I send them chess puzzle PDF to solve from chessgo.in
You confused tactics and puzzles, dear Avetik. I am genuinely surprised a mistake like this could happen to you. But it gives me hope that we are all humans. :-)
Hello

I reaaly enjoyed this post. I'm a player who make a lot of chess puzzles here on lichess, but my rating isn't improving, and there are many positions that i don't have any idea about the correct move and why.

I have thinking a lot about study strategy to help me solve problems like this, but I never know if I have rating enough to learn some things from the books.

Can anyone give me some advice about this? With recpect this post, what books do you recomends to start and improme my strategy? Yusupov (Yusupov), Winning chess (Sairawan), Modern Strategy (Pachman), others?

Thank you guys.

What is the difference?
Puzzles are the "flashy" part where one side gets a decisive advantage with exactly one series of best moves. Training puzzles does indeed have a limited (but not vanishing!) amount of usefulness, especially if you focus on doing a lot of them and quickly rather than a few properly. (Thanks to all these "fun modes" like Puzzle Rush, Puzzle Racer, Puzzle Streak etc...)

Tactics are much more broad discipline of calculating correctly and precisely. They can also be implicitly trained by (properly) studying GM games, middlegame books, endgames, and so on.
Tactics do not necessarily lead to one side having a big advantage or even any advantage at all, and in fact a lot of them won't. But they are nevertheless irreplaceable and any intermediate player couldn't survive 10 moves beyond opening prep without tactics.
While puzzles are only about spotting the instant win, tactics are also about being precise or not making losing mistakes.
