Something about that video is fishy? First he gets on Houdini for calling Na4 a draw saying Houdini blunders but then he tells us it is a draw? Sure! Engines need time and are not infallible but I am not sold on what he is saying enough to attend his webinar. Besides I was always told to best way to analyze a game with an engine is to go backwards?

Yes Tom, that is why waited until after it was over to share. :wink: Note I did not attend the webinar, but I thought the subject however might be interesting to share.

Good catch Ferdinand, I used Analyze This to quickly recreate the position and grab the fen.

Deuterium current development version crashed in pgn master even in analyze this, so these gui's seem to not verify the castling rights too,
so I implemented now verifications of castling rights in my fen parser.
