Spaced Repetition

<Comment deleted by user>
This blog seems to have many practical informative bits. (I fast read, and might have had blind spots, for now).

I zoomed in the following paragraph, which itself is a zoom out on the blog topic.

> You might have noticed that this is quite similar to the Woodpecker Method, which also advocates for training the same tactics repeatedly. The difference is that whereas with spaced repetition you review the same material at increasing intervals, in the Woodpecker Method you review them at decreasing intervals.

And then a dissonant bit, not agreeing with my understanding of that type of time scale aware long term memory framework.

> This may be a bit less sound pedagogically, but again, as long as you’re working on tactics every day you’ll be fine.

I had been exposed to such concept long ago, and it was not in chess context, but I think psychology of learning. I took home that long term memory (associative memory), would get consolidated as a principle (or empirical notion here), which such increasing iteration of exposure and recall testing. That is was pedagogical.

Maybe we are talking about different objective of learning. One may be precision of fast motor skills as objective, the other might be more about reducing via regrouping the most robust associations to keep long term for efficient reorientation with further experience exposure possibly itself new. The precision objective might be assuming a constant environment upon which to optimize execution speed. For the external observer, both a fast reorientation in a new context, or a fast execution in a similar context, would look equally of digested expertise nature.

One is to make the material technique status.. The other might be from of internal model building and épuration of mechanistic associations.. that last statement is itself out of my intuition and has hypothetical status.. might be BS. sorry for the french, it is either that or more babble to torment the reader.

Edit: I also like at the end the zooming out again, to refrain from magic bullet one tool, king of the mountain. and even more, maybe not stated as such, the idea to use comparing and looking for contrast as well as commonalities among different angles to the same "thing". My words might have distorsion, but this is what the 2 tubes videos on same opening reminded me of (here the comparing would the narrator point of view, possible contrast in emphasis or idea ordering, idk).

The recall added task is more than just memorization (as in storage retention).. I think it is the difference between appropriate expression, and passive recognition of a pattern. Knowing when to use the stored pattern.
for lichess puzzles past mistake spaced repetition, the day timers of the user past history in all the drop down menus when themes are involved, makes it difficult to use spaced repetition (even vaguely done) over more than 3 months (90 days).

also, if succeeded once the past failed puzzle being replayed will lose immediately its failed status.

I have been wanting to look over long time periods on my puzzle history for a long time. So it might be better to keep the initial fail status flag somewhere for user review at any time scale..

I don't know if in chess the concept of space repetition has some expiration date or 3 months maximum time scale.

It might be only considered for intensive improvers on a mission. not other users.. still having own pace of progressions ambitions. In any case. your blog content might be an argument for lichess to revise its user controlled features about experience history retention.

Idea: if there are resource considerations limiting amount of puzzle ids to be compiled in those features, why not use the amount of Ids, not the date of first attempt. maybe not the reason for the cap, or the choice of date as the cap limiting factor.
I really like the chessbook.com website you recommended. Too bad it costs money to fully make use of it.
Is there a free alternative to it?
Yep. I think lichess should get inspired.. maybe a global spaced repetition scaffold for many things... say on top of the puzzleification of study chapter layers.... having some time aware memory of attempts....

just a suggest not a destructive criticism.. There might be an open source niche there.
BraiMax chess offers spaced repetition for tactics. It is still in development and being worked on but I am using this almost exclusively for my tactics now.

I just tried the chessbook website. Imported my whole pgn repertoire into it and it was a buggy disaster. It tried to say my repertoire included 6 opening moves (I only imported 1.e4 files) including e4, d4 and total nonsense like 1.gxf3. This is not ready for primetime, though I did like the ideas.
