Surprised!!!
Indeed, the question might surprise you. In real life, there are many problems which keep on popping its head out for pawn promotion than you can imagine. There are many reasons for this sad phenomenon. We can partially consider it as FIDE's fault as they have created complicated chess rule. It reminds me of a chess joke that the chess arbiter or expert is the one who disappears during the tournament.
The main skill of a good tournament director is to prevent any problem before it even appears. These days chess arbiters need to be accredited by FIDE and simultaneously they have to participate in the endless arbiter seminars. It is very profitable business for FIDE and hence it makes perfect sense for it to make chess rule more and more complicated, and inventing doping tests, “Zero tolerance” rules, etc.
In Women’s World Blitz championship as you know than an illegal move was punished by instant loss in blitz, so it is mandatory to follow the official rule.
It is both happy and sad to watch arbiters teach an international master how to promote pawn.
It looks like as FIDE polishes the rile on a monthly basis, you can never be sure. A well- known Russian grandmaster and trainer admits on that he doesn’t know anymore how to promote a pawn.
