Stockfish 15 vs Magnus Carlsen?

Readers of this blog are familiar with Yury V. Bukayev. Recall his most recent post, "JG: The New in Its Opening Theory, in Its Psychology (Part 14)".

Recently, Yury sent me a link to a fascinating video featuring an animated impression of Stockfish. (See "Stockfish 15 introduces himself"). 

The video, "Stockfish 15.1 (4k Elo) Sacrificed his Bishop Against Magnus Carlsen | Magnus chess | Online Chess" starts with Stockfish asking "Chess friends do you ever sacrifice your bishop for no reason?"

There follows a game - unfortunately not a Jerome Gambit - with the following information 

    Game: Bishop Sacrifice For no Reason

    White: Stockfish 15.1

    Black: Magnus Carlsen

    White Elo: "4023"

    Black Elo: "2864"

    Time: 15/3

    Opening Name: B07 Pirc Defense, Botez Gamebit Bishop                Sacrifice

    Date: 26.12.2022

This header is funny.

(By the way, some have suggested that the Jerome Gambit, itself, features piece sacrifices "For no Reasons".)

I am not the first person to speculate that the "Magnus Carlsen" in the game might have been a chess bot, not the real live chess champion.

The game began 1.e4 d6 2.Bc4 Nf6 3.Bxf7+ which is what caught Yury's eye.

If "Gamebit" is a mis-spelling of "Gambit", then the reference to the Botez Gambit is understandable. Recall the blog post here from earlier this year, "The Jerome-Botez Gambit".

The game?

Apparently Magnus Carlsen wanted to "avenge" that loss as a few days later there came the video "Stockfish 15.1 (4K Elo) Sacrificed His Bishop in the Opening | Stockfish vs Magnus | Fide magnus" but with no vindication, alas (Stockfish as White)

Hmmm... The "world champion" being thrashed, twice.

Hard to explain.

Although HAL 9000 (from "2001:A Space Odyssey") might have commented that "It can only be attributable to human error."
