There was some discussion in twitch chat today about the chess game in question, and an incomplete VOD / missing pgn(*). Having watched (if it matches up correctly) the end of the game in question (live), I thought it was an interesting challenge to reconstruct a start point from the partial pgn and finishing FEN (moves 17-42). I have a passable version of events, at least no obvious (to me) blunders, and it somewhat matches my memory of the event (particularly the bishop skewer).
