is this from Ognjen Amidzic's research on chess and memory?

MESON is comprised in part of card index collections of chess problems and puzzles.

Compiled using a variety of sources including card indexes.

As for the Pirnie collection, not counted it, but I am slowly going through it for my online #ChessProblem database: https://t.co/eTDrPnX09b . Also going through several boxes of the White-Hume Collection which I have.

Presumably Genrikh Kasparyan used his card index of chess puzzles as material to write one of his many books including: - Domination in 2,545 Endgame Studies by Genrikh Kasparyan. ISBN 0-923891-87-0 - 888 Miniature Studies by Genrikh Moiseyevich Kasparian. ISBN 978-86-7686-147-7

As a chess champion, he surely used to to fuel his chess studies and chess career.

It Took Decades To Create This Chess Puzzle Database (30 Thousand), 2020. https://www.youtube.com/watch?v=Y9craX0M_2A.

A chess School named after Genrikh Kasparyan (alternately Henrik Kasparian) houses his card index of chess puzzles with over 30,000 cards.

The cards are stored in stacked wooden trays in a two door cabinet with 4 shelves.

There are at least 23 small wooden trays of cards pictured in the video, though there are possibly many more. (Possibly as many as about 35 based on the layout of the cabinet and those easily visible.)

Kasparyan's son Sergei donated the card index to the chess school.

Each index card in the collection, filed in portrait orientation, begins with the name of the puzzle composer, lists its first publication, has a chess board diagram with the pieces arranges, and beneath that the solution of the puzzle. The cards are arranged alphabetically by the name of the puzzle composer.

The individual puzzle diagrams appear to have been done with a stamp of the board done in light blue ink with darker blue (or purple?) and red inked stamped pieces arranged on top of it.

Maths, Logic, Computer Science, Chess, Music, and Dance

A similar observation could be made about mathematics, logic, and computer science. Sadly, public education in the states seems to lose sight that the formalisms in these domains are merely the tools of the trade and not the trade itself (ie, developing an understanding of the fundamental/foundational notions, their relationships, their instantiations, and cultivating how one can develop capacity to "move" in that space).

Similarly, it's as if we encourage children that they need to merely memorize all the movements of chess pieces to appreciate the depth of the game.

Or saying "Here, just memorize these disconnected contortions of the hand upon these strings along this piece of wood. Once you have that down, you've experienced all that guitar, (nay, music itself!) has to offer."

Or "Yes, once, you internalize the words for these moves and recite them verbatim, you will have experienced all the depth and wonder that dance and movement have to offer."

However, none of these examples are given so as to dismiss or ignore the necessity of (at least some level of) formalistic fluency within each of these domains of experience. Rather, their purpose is to highlight the parallels in other domains that may seem (at first) so disconnected from one's own experience, so far from one's fundamental way of feeling the world, that the only plausible reasons one can make to explain why people would waste their time engaging in such acts are 1. folly: they merely do not yet know their activities are absurd, but surely enough time will disabuse them of their foolish ways. 2. madness: they cannot ever know the absurdity of their acts, for "the absurd" and "the astute" are but two names for one and the same thing in their world of chaos. 3. apathy: they in fact do see the absurdity in their continuing of activities which give them no sense of meaning, yet their indifference insurmountably impedes them from changing their course of action. For how could one resist the path of least resistance, a road born of habit, when one must expend energy to do so but that energy can only come from one who cares?

Or at least, these 3 reasons can surely seem like that's all there possibly could be to warrant someone continuing music, chess, dance, maths, logic, computer science, or any apparently alien craft. However, if one takes time to speak to someone who earnestly pursues such "alien crafts", then one may start to perceive intimations of something beyond their current impressions

The contorted clutching of the strings now seems... coordinated. The pensive placement of the pawns now appears... purposeful. The frantic flailing of one's feet now feels... freeing. The movements of one's mind now feels... marvelous.

So the very activity that once seemed so clearly absurd, becomes cognition and shapes perspectives beyond words

There is no one who can beat Magnus Carlsen in our lifetime. The contenders whom I hope would be able to do that all fall short in doing so. Their nervous system just breaks down. Wesley So is just sooo serious he needs to ligthen up. Anish Giri lacks the killer instinct. Fabiano Caruana is so temperamental.

Magnus Carlsen is well-balanced chess player. I

What an embarrassment! Kick him out forever!!

This sounds like Renfield detailing certain chess matches.
