Knight on rim, prospects are dim

Apparently the following the game was the result of some deep preparation by Mamedyarov against MVL's Grunfeld Defence. It also demonstrates the maxim about having a knight sitting on the edge of the board. And while the resignation may look a little surprising, Black is out of useful moves, and White is at least +4 according to Stockfish.
