The Secret of Chess 2

[Lyudmil Tsvetkov]

The second volume of 'The Secret of Chess', containing example games, is out.
803 games in total.
The games follow the Table of Contents of the first volume, covering each and every term.
Some terms are covered by a single game, while others, more important ones, by as much as 15.
The volume features 5 world champions, among which Carlsen, Kasparov and Fischer, 3 top engines, Stockfish, Houdini and Komodo, as well as a number of other players.
I have browsed 15 000 games to carefully select those 803.
All games are tactical and positional masterpieces.

The book is available here: https://www.amazon.com/Secret-Chess-Exa ... dpSrc=srch

I guess everyone, programmer or chess player, who has found the first volume interesting or would like to clear his ideas on the concepts, should have a look at this one.
For the time being, the games are unannotated. It will take couple of years to fully comment 800 games, so I wanted to have this consolidated version out.
I guess at some point there will be also a volume with annotated example games, but this will not be too soon. And I am not certain what portion of the games will be featured there, probably just a smaller one.
The main reason for releasing this volume is that many people asked me for illustrative games to better comprehend the concepts. Initially, I had not considered this at all.

Please, everyone, don't try to troll this thread again.
If someone has chess/programming-related content or comments on substance, feel free to post. Otherwise, maybe find yourself another thread.
The same appeal goes to the mods to be more patient.
My book/project is an interesting one, posting here is useful both for me/my contributions, as well as for the people who would like to get some info on this subject.
So, just take a calmer approach.

Just to mention that the comparison between top engine and human play in the collection is an interesting observation.
We all know that top engine games last much longer on average, and the collection will only corroborate that.
But there is one more interesting phenomenon I discovered, namely that top engines tend to use some terms more often than humans, that would concern in particular for some reason outposts, especially more advanced ones, and material imbalances.
Why so?
Still not fully certain, but maybe one of the reasons is that the human imagination on average will have bigger problems with some lines, requiring deeper or highly unusual calculation.
So that chess changes, there is no doubt about that, and we will be seeing further very interesting developments in the future conceptually, no doubt about that.

Still not fully certain, but

Oh no, I can't believe it! Is there actually something you don't know?

..., there is no doubt about that, and ..., no doubt about that.

Ah, what a relief. Things are back to normal!
Such calming, reassuring words: "no doubt about that". Let's all inhale deeply, hold it there for a few seconds, slowly exhale and repeat

no ... doubt ... about ... that

Can you feel the calm spreading about? Sheer serenity.

Thank you, Lyudmil; looking forward to volume 3.

I have to thank you, Mr. Poppins, and you know about what: because of your precious help with pgn utilities I was able to clean my file.
Thanks.

And here is my chess content, the chess content which would obviously have hidden the links in a larger thread, making everything completely normal.
The chess content, which presumably is of such an interest to every chess/chess engine lover on this forum.

Just to demonstrate how concepts are illustrated in the second part, below an example game.
The game illustrates the 'spearhead connected passer' term.

SF does not see Ba4 wins for black here.
It does not even know black is better after that, or in the current position, for that matter.

Such are my concepts, deep and innovative.
People should not do new things and contribute substantially to the chess community: they are likely to be punished.
