Thanks so much for posting!
The Most Important Concept For All Beginners...

Thanks.
I've considered blogging about stuff like this... essentially taking the most instructive or interesting question I saw on the forums and answering it in a blog.
If I had started doing that 10 years ago, I'd have made 100 good lessons by now heh
You can't start ten years ago, but you can start now
I suspect more people will read on the forum though...

Hey! You should join my facebook group " Chess Passion", i'm building a community for making new friends and share about Chess in general, i'm sure you'll learn something or at least have a good time ! See you soon ! Thanks ❤

I think instead of looking at pieces, perhaps it's better to look at squares: which squares are threatened, which squares will be threatened etc.
The squares may or may not contain a piece. Your king may or may not be involved, if he is, a check threat.
So this can be helpful to develop the habit of defending a square, not necessarily defending a piece.
An analogy from football (soccer): man-to-man marking vs zonal marking.

One of the most useful / important things you can do when you influence a square, and your opponent has less or no influence, is to infiltrate into their position. However controlling squares and infiltrating are just a means to an end. The ultimate goal is always coming into contact with vulnerable pieces (pawns and the enemy king are typical targets) and eventually overwhelming those targets (or ones that emerge when the opponent tries to defend).

One if the ways to improve calculation habits is to always end your calculation with opponent's move. In this way the threats and check are automatically talen care of and you will be easily able to analyse long variations. Hope it helps. Thanks for a great advice.

Of course it's hard because you should pay a lot of attention to every your move... from the beginning to the end of the game.
The game turns into the hard work without pleasure. )
So I think we shouldn't eliminate hope in chess and hope in life... And we shouldn't substitute it with simple calculation.
Playing without romantic is boring.
Excellent post. Although I think it is more of an intermediate concept rather than a beginner's concept.
Also, as korotky_trinity noted,

So it may be the approach to use to win the most games, but it isn't necessarily the one that is the most fun.
And unless someone can do lightning-fast calculations, it will be impossible to use in the fast games that are so popular these days.
I wanted to add to the thanks for such an excellent post. I don't mind at all that it bumps this thread
I have always thought of "Hope Chess" as a form of confirmation bias. In looking for reasons why a candidate move is good, confirmation bias leads us to only consider the opponent moves that make the move work. So I see the 3 responses that make a move great, and overlook the forced mate in 2 I have just created. Instead, we need to be scientific and actively try to prove that a candidate move is bad. Your strategy is perfect for that.
Also, if you had a blog with stuff like this, I would follow for sure.
Thanks.
