This looks amazing! To generate multiple (almost) equal positions with a given set of pieces can be handy while practicing. I love that there is a way to analyze it on Lichess as well. Would it make sense to export a PGN file of the position as well?

I'm not sure how to put it, but would be great to also include an option to simulate a position with a given opening. For example, 15 moves down the line of playing Queen's Gambit accepted variation with the given pieces on the board would be instructive in learning what's an equal position and how to improve middle game etc. Maybe too hard to implement, I understand.

I saw your submission on r/chess also.

Thanks! Good idea, I could add FEN / PGN export in addition to lichess. I haven't tried conditioning the network on opening but given my training data, that should be possible. For now, you can simulate openings somewhat, by trying to fix pawns and pieces in their typical positions, but it would be better if I could do it like you suggested "QGA, 15–20 moves" etc. I might try this out!
