The above program if loaded into Stockfish 10 with File/Open errors out stockfish with the error

"The document could not be opened"

Despite the 100+ other games in a related file it was extracted from being able to be fully opened in Stockfish 10.

Thoughts?

You did not even bother to replay the 'game', before asking?
In this case you would have noticed that 21. g3 cannot be executed in the javascript,
because it is an illegal move...

Obviously blind. Longstanding bug in my program where it did not check the legality of the move played by the human after entry at the main command loop.

Checks in search were correct.

Fixed and move on.
