As a training idea, I can recommend going over the raw game score without annotations and without an engine. Try to figure out the game for yourself-- especially try to see where the loser could have (1) avoided problems in the first place and (2) defused Spielmann's initiative. After you have reached your own conclusions, you can consult the video (or the book or an engine) to compare your conclusions. For this purpose I am giving the PGN file below. Here is also a link to purchase the book.
