No? I never heard of that before, but I do know moving the king up to the opponent's side and back would be extremely unnecessary and would never happen. As said above by @Brian Towers, the main point of the game is to checkmate the opponent's king. The king is the target, and needs to be protected for a stable and safe game. Running the king around the ...

No. The whole point of the game, the way you win, is by checkmating the opponent's king. If your opponent could exchange the king for another piece then you would no longer be able to win. In any case, all the pieces except the pawns can move backwards. Without promotion any pawn which reached the 8th rank and couldn't promote would no longer be able to move....

I'm not sure about a world championship game, but genuine underpromotions do occur now and then in grandmaster games. For a starting shot, here is the famous 2012 game with a knight promotion by Hikaru Nakamura. According to the FIDE rating website, Nakamura's *rating at the time was 2783 the month game was played. By "highest level," I took that ...

It seems as if the puzzle is based on an actual game played between Jorden van Foreest and Martin Petrov in April 2019. If you click on the button to show the solution, it shows the full game, of which the puzzle is but a fragment. It looks to me as they want you to solve the puzzle by following the game as played, not by coming up with another solution. The ...

It is a quirk/bug of the software used by that site to pick moves expected in puzzles.

If anything, promoting to a queen is the better choice, as it forces Black to exchange their rook. For promoting to a rook, Stockfish NNUE actually slightly prefers moving the f5-rook away instead of playing ...Rxf8 (although any continuation gives White a large winning advantage). So at the very least Black is given a choice. But even if we were certain it'...

For an engine, it makes no difference if you promote to a rook or a queen. In both cases, your advantage is huge. There is no real resistance for black, but his best chances, if any, are to give his rook for the promoted piece. 3.f8R Rxf8 and 3.f8Q Rxf8 result in the same position. No difference. But chess puzzles have their own etiquette. And one of the ...
