Oct-19-22  boz: Picking up his opponent's king is strange. Then throwing it back onto the board on the wrong square is equally strange and makes it all seem deliberate rather than hallucinatory.
Oct-19-22  stone free or die: Really gonna get back to the mines, but this game's episode has inspired a movie recommendation -

Outstanding.

I would have thought Sevian would have been forfeited. I mean, So wrote notes on his scorecard and was gone. That's nothing compared to what Sevian did.

  Check It Out: "Break King Bad"

that's pretty funny, nok.

Oct-19-22  jerseybob: <DanLanglois: The thing this game is really to be known for is this controversy: Sam Sevian literally breaks Hans's king.> Maybe Sam had an attack of the munchies and he thought the black king was a piece of dark chocolate? I'm sure the usual conspiracy mongers will weigh in on that. But my question for you <DanLanglois>is: Why does your search for "how Sam could've saved the game" start on move 30? By that time white already had the nasty doubled isolated h-pawns and was the exchange down. I went through several of these Hennig-Schara lines and don't see a magic bullet for white, although maybe Nxe6 around move 10 or 11 might give him something to work on. But Sam disdains that and keeps searching for the win that's not there. And kudos to Hans for trying an "inferior" opening.
Oct-20-22  jerseybob: <DanLanglois: But anyways, Black played 22...Bg4:> Correction, my apology! It was move 22. But I'm still puzzled: Why doesn't your analysis start at move 1? Looks like you posted it but it didn't go through?
Oct-20-22  DanLanglois: <jerseybob>, I do recall having a post about the opening, and then deleting it. It was just not fully explained or understood stuff.
Oct-20-22  jerseybob: D.King does an excellent video on this and the 'King Grab".
Oct-20-22  DanLanglois: I wonder how this needed to be 78 moves after 53...b1=Q:

54. h4 Qg1+ 55. Kh5

Here, Black's priority, I figure, is to eliminate Black's pawns. Keeping with check and check and check, Black can do this. Thus, 55...Kb3?! doesn't seem on point.

Instead, 55...Qd1+ 56. Kh6 Qd6+ 57. Kh5 Qd5+

58. Kg6

Now I was talking about eliminating Black's pawns. Maybe this hanging pawn, take it now? But here, Stockfish comes up with a 'better' idea, to stick with check and check and check and thus, supposedly vastly better, Black plays 58...Qe6+:

59. Rf6 Qg4+

60. Kf7

Now Black takes the h-pawn, the one that is actually passed 61. Qxh4:

Black doesn't, for his own part, have a check here. Wicked.

Back to the game, Black actually played 55...Kb3?!

56. a6 Kc4 57. Rg7

Here, Stockfish assistance queries Black's move, which was 57...Qc5+. What I would note first, is that at this point White still has both of those pawns. Stockfish comes up with 57...Qf2 or 57...Qe3. These are eval -11.27. But Black's 57...Qc5+?! is apparently sloppier:

White contemplates 58. Kh6 at like -8.72 eval, here. Black can get the job done. Yet actually, White plays 58. Rg5?:

For that, Black has again ideas in the range of -11.72 eval, at least four moves to choose from.

58...Qe7:

Kind of a technical won endgame, where you can come along and see the stockfish execution and wince at the actual game, move by move.

Oct-20-22  jerseybob: <stone free or die: Bend, don't break...Here's Hans chalking it all up to a little misunderstanding:> Hans comes across as very normal, while Sam Sevian? Hmm
Oct-20-22  jerseybob: 11..Rc8 is Niemann's improvement over 11..Bb3 as played in Sevian-Xiong in Rd.6
Oct-20-22  Granny O Doul: I also like "break king bad", though maybe it could use some punctuation, such as a dash or colon after "king". It reminds me of the Edmar Mednis book "How to Play Good Opening Moves", which is full of such wisdom as "if you leave pawns unprotected--this will be bad".

Oct-20-22  jerseybob: <DanLanglois: <jerseybob>, I do recall having a post about the opening, and then deleting it. It was just not fully explained or understood> What's the program you use to generate that content?
Oct-23-22  DanLanglois: Stock fish? No secret, I mentioned that. You presumably already know you can generate your own diagrams, by hand or using arena or such, to generate the code..?

Oct-23-22  jerseybob: <DanLanglois: FEN Help Page> I've known this diagram method for some time, though never knew its official name. Don't have SF, but thanks for the info.
Oct-23-22  DanLanglois: Any chess GUI (WinBoard, Scid vs. PC, Arena, Tarrasch, Fritz, etc., etc., etc.) along with any of the top chess engines (Houdini, Stockfish, Critter, Komodo, Rybka, etc., etc., etc.) will be able to analyze your games for you and suggest better moves.
