FEN stands for Forsyth-Edwards Notation, a clever system for encoding a chess position into a single string.
Make some moves and the table will fill with timestamped YouTube links featuring the current position. Indexing is slow and more videos are added constantly. I'm prioritizing early positions (first ~20 moves) of educational content to start.
For example, try Ruy Lopez, Queen's Gambit, or Sicilian.
