Modern study methods include active recall (guess-and-check) and spaced repetition (answering correctly makes the question come back later, answering incorrectly makes the question come back sooner). Board game puzzles are inherently active recall (as opposed to passively reading someone else’s game’s moves), but don’t inherently use spaced repetition. Spaced repetition works really well for languages, and I suspect that doing puzzles from easiest to hardest with the scheduler (approximating after how many months you may forget a certain strategy) works better than attempting random puzzles at your current elo rating, like most people do.

I personally use Anki (an active recall/spaced repetition/digital flash card app) with FSRS (an open-source review scheduler using the Difficulty-Stability-Retrievability memory model similar to how SuperMemo does).

In order to individually schedule reviews for each puzzle, I need to access each individual puzzle, by A) somehow copy the entire scripting/move list/ai player/database into local offline html flash cards or B) link to the puzzle’s url or C) the text of the card tells me where to manually go find the puzzle, even if it’s in a hardcover book. B is the easiest option.

A quirk of Anki is that, while each flash card is an individual html/css/js page generated from text fields stored in an sql database combined with an html template, when you are reviewing and switching from one flash card to the next, the internal pyqt6 web browser’s hidden address bar url isn’t changed. Instead, the content of the page is swapped out using rust/python/typescript/javascript to render the next page. So in order to render external content I need to A) embed it in an iframe unless that fails because of x-frame-options, or B) use javascript to change window.location.href which opens the puzzle externally in the default web browser and I have to manually (or with greasemonkey/autohotkey) close the tab and switch windows when I’m done, or C) write an addon to change the url and back, and addons only work on a pc, not android/iphone because of play store sandboxing rules (I wrote one incorrectly, so sometimes when flipping to the next card it can get stuck on a blank page and I need to leave/re-enter the study session to see the next card)

As far as I can tell, there is no rhyme nor reason as to whether a site will disallow iframe embedding.
refused to connect: checkers, sign language dictionary, rna folding
connects: blackbox, chinese/japanese/korean/laser/normal chess, connect four, draughts/frisian, spanish dictionary, dna alignment, go, hashi-o-kakero, nonograms, rush hour
checkers, dictionaries, and biochem are on both sides of the fence.

Please stop sending x-frame-options:SAMEORIGIN, at least for …/problems/*

Testing: To see whether that header is sent:
Firefox or Chrome→right-click→Inspect (Q)→Network tab→press F5 to reload the page→scroll up and select the first GET/document/html row→right sidebar→Headers→scroll down→Response Headers→scroll down→x-frame-options:SAMEORIGIN
or save a .html file containing <iframe width="100%" height="100%" src="https://www.checkercruncher.com/problems/755"></iframe> and see if it loads

That’s an interesting use case, not one I thought of. I hope you find a work around that works for you,
but this is not something I can turn off. The Same-origin policy - Wikipedia is an important security layer for problem comments and anything else that allows user generated content.

For the problem comments, I’m pretty sure they don’t allow weird html or JavaScript shenanigans but in case I missed something, I’m leaving the same-origin policy on.

iframe blocking is a coin flip masquerading as security, and both you and qtwebkit flipped tails.
I need to do one of:

  • get checkercruncher to stop blocking iframes x-frame-options:SAMEORIGIN → Content-Security-Policy: frame-ancestors 'self' http://127.0.0.1;
  • find an alternative checkers (not draughts nor frisian) website or database+js
  • get official anki desktop & ankidroid builds to always compile with a custom fork of qtwebkit that has a modified FrameLoader::shouldInterruptLoadForXFrameOptions() to at least have the option to load it that firefox and chrome have
  • get qtwebkit to support browser.frames.enabled
  • switch to a qtwebkit alternative
  • use an internet proxy that strips the X-Frame-Options header (though my internet hotspot app already uses the VPN feature slot on my phone)
  • study checkers separately on pc with my custom iframe2internal addon instead of mixing board game decks on the phone
  • track down why the card template’s javascript no longer opens a new browser window per puzzle in both ankidroid’s old and new reviewer
  • modify anki desktop and ankidroid to use setURL() to visit the website directly (like the addon does) while still being able to access the flip/grade grade buttons through gesture/key/screen button, and then reloading the reviewer instance to load the back of the card from localhost.

A proxy doesn’t work. It can strip x-frame-options and content-security-policy headers but only for websites that don’t force https. https://stackoverflow.com/a/62055479 “www.checkercruncher.com is most likely a safe site, but a secure connection could not be established. This issue is caused by mitmproxy, which is either software on your computer or your network. www.checkercruncher.com has a security policy called HTTP Strict Transport Security (HSTS), which means that Firefox can only connect to it securely. You can’t add an exception to visit this site. MOZILLA_PKIX_ERROR_MITM_DETECTED”

I’m sorry, I know it’s frustrating, but I believe this to be operating as intended.

#6

Now it works on the phone (was missing a quote), newer desktop anki 25.07.5 (_page broke), and with the last function I can now return to a local card after doing a remote one without it getting stuck, so I can mix different games in the same review session (mw.reviewer.web.setUrl() then mw.moveToState("review")). Also checkercruncher requires me to be logged in before I can move with one tap, and that applies on the second card because I didn’t get the timing right yet.
This is how I have it as-is, less user cookies, without cleaning up dead code/comments:
