Queen's Gambit?

Hey

I recently watched the Queen's Gambit series on Netflix and since I like to play chess myself, I also took a closer look at some games that are partly inspired by grandmaster games.

My question, however, relates more to a chess position in episode 5 in the middle of the episode. There Beth plays a training game with Harry, who replies to one of her moves that she has made a mistake because she is sacrificing her knight. However, she explains to him that the move can gain an advantageous position during the course. Since the board can't be easily recognized in the scene and it is difficult to search for the game on the Internet, since only this position is shown, my question would be whether someone can explain your move or the sequence of moves that follows.

A picture of the position on the chess board would be extremely helpful.

That is the problem there's no real picture because it only appears briefly. I have now added a screenshot of the scene on which the board can be seen.

Unfortunately, you can hardly see anything in the picture.

Yes I know. Unfortunately there's no better. The question was directed more towards those who know the series and can follow the scene and its explanation without a board.

I know the series, but I don't remember the scene by heart.
