After seeing a lot more chess related content in the last month [1] and just two new ones hitting the front page in the last two days I thought I should share my passion project Listudy. It started as a rewrite of my opening trainer from go [2] to elixir [3]. Since then I added endgames, tactics and what I call "blind tactics", which I added to train my visualization skills. I hope this helps you as much as it helped me get better at chess.
