Makes me think of embedding an overlay filesystem / OS over twitter lol.

Its a PNG that can also be executed as a Java program. You can create your on PNG's with data using: https://github.com/DavidBuchanan314/tweetable-polyglot-png

This was made by David Buchanan on Twitter. He explains more in his Twitter post and on Github. It seems like a really cool idea to incorporate into a puzzle, so I figured you guys would like it.

A security researcher has discovered a novel steganography technique for hiding data inside a Portable Network Graphics (.PNG) image file posted on Twitter, a tactic that could be exploited by threat actors to hide malicious activity. Researcher David Buchanan heralded his discovery on Twitter earlier this week, accompanied by a photo declaring: “Save this image and change the extension to .zip!” He made the source code for his method available in a ZIP/PNG file attached to the image as well as on a post on GitHub that explains his methodology.

If you do get around to the pi version- I highly recommend this library python-chess. It can handle valid moves in addition to querying an engine like stockfish.

There is a very good Python chess library for computing these sorts of things: https://python-chess.readthedocs.io/en/latest/ If you backed the board with this, you could do it pretty easily.

I've never done it, but it should be quite easy with python-chess to read in a detailed opening book, go through each game, and then find the last position in each game that occurs in the opening book.

pip install chess https://python-chess.readthedocs.io/en/latest/

database.lichess.org I use the python-chess package.

The tool requires this library to be installed.

python-chess

Do you need to reinvent the wheel? There's python-chess, for example: https://python-chess.readthedocs.io/en/latest/
