Fischer plays 17... Be6, leaving his Queen hanging.
Standard narrative: "Fischer offers his Queen for a mating attack!"
Engine reality: 17... Be6 is the correct move. Trying to save the Queen actually loses the advantage.
Byrne taking the Queen (18. Bxb6) was a massive blunder. The engine actually wants Byrne to ignore the Queen and trade off Fischer's Knight on c3. He ends up with a Queen stranded on a3, a total spectator
This is a common theme, gambits are such depending on what your level and calculation depth is.
The queen's gambit opening (almost inarguably a gambit as it is part of a well accepted name of a second move), really isn't a gambit in the sense that you can always recover the pawn, however it is a gambit in the sense that you temporarily give it up.
If we were particularly short sighted, no doubt, responding to an early white bishop threat on g5 or b5 with a knight on f6 or c6 would look like a gambit, as we are sacrificing the knight, but lo and behold, we regain the minor piece afterwards with xf6 or xc6!
The distinction would be whether the gambit or sacrifice is solid or refutable. But it is in both cases a sacrifice.

Not surprised at end re classical position not being the most even configuration. In that configuration bishops & knights practically start aimed at controlling center, so there's little awkward properties to dampen White's initiative. One of the rooks even get to castle out of the corner
Chess960 would be better if they just got rid of castling in it, tho wouldn't be surprised if that makes for certain positions getting even worse for Black
Chess960 would also be better if both sides were asymmetrical and there were novel positions for both players in every game.
I go to a chess event 2-3 times a month in the city where I live, and there are a few of us that are big into variants and play a lot of Bughouse, Crazyhouse, Racing Kings, etc. 960 is a bunch of fun but asymmetrical 960 is a blast, and asymmetrical Bughouse 960 / Crazyhouse 960 is the most fun and hard version of chess I've ever played. There is no theory, just pure tactics and reaction.
Probably many asymmetrical combinations are unfair to black. Maybe running through combinations and simulated games with a chess engine could identify ones that are fair, asymmetric and fun? Then a database could be built up of these combinations and it could be randomly selected to start your game.
Similar idea is randomized openings. Checkers does this already. TCEC does chess AI tournaments using sharp preselected openings (matchups playing 2 games, one of each color)
I can't say for 960 specifically, but for standard chess getting rid of castling usually results in the players just manually castling their kings. I believe that is why the move was introduced in the first place. So it really doesn't accomplish much except make the opening a bit more limited, since they have to leave themselves a way to manually run the king over one of the rooks. Usually to the short side, since that's quicker. Basically makes queen side much less viable to leave the king at. And queen side castling was already the rarer of the two options.
I imagine it would be a similar story for a lot of 960 positions. I'm not sure how getting rid of castling would benefit anything. In 960 you already get a lot of super crazy aggressive positions with exposed kings even with castling.
They’ve defined memorization complexity as having to memorize the best out of almost equally good moves (as opposed to being able to play the best move without memorization because it is so obvious.
In reality it’s almost the other way around. Because white usually has several good moves at every point, they can just memorize one of them, while black needs to memorize how they’ll respond to every good move white could make.
Ironically the starting position that I've found to be the most balanced for black and white is just swapping the starting square of the bishops and knights.
It turns normally-sound opening moves like 1.d4 and 1.e4 into liabilities and emphasizes the knights as blocking material to occupy squares like d2 and e2 , but the tradeoff is that a early-developed bishop can get a lot more active centrally via an open wing.
Such a layout makes for a very cautious opening phase where neither side really feels comfortable giving up much material. Really a fascinating setup.
interesting that the most balanced one is extremely similar to the default, which is not so:
> \#198 (\texttt{QNBRKBNR})is the most balanced, with both evaluation and asymmetry near zero... Remarkably, the classical starting position-despite centuries of cultural selection-lies far from the most balanced configuration.
That formation is pretty close to the standard position though. Just swaps a Queen and Rook. It puts the Queen in the corner, a less aggressive position with less options to develop.
I've only played a little 960, but these queen in the corner positions seem to often lead into more closed positions.
Yeah, agree, but in the setup you mentioned, 1.b3 and 1. b4 are both strong moves, because it basically forces the game to develop kingside from the get-go.
Seems the opening can get really sharp, or basically a race to bunker via 1.Nf3
"Remarkably, the classical starting position-despite centuries of cultural selection-lies far from the most balanced configuration."
Right, balance would be one of many parameters that make a game popular. Complexity is even a positive aspect of a game, a simple game with a simple optimal strategy would not be the most popular.
Simplicity of rules is another parameter, the classical configuration is somewhat symmetrical on the Queen King axis, many candidates would provide a rather asymmetrical and hard to remember initial configuration.
I've been analyzing classic "romantic" games using Stockfish with multipv (showing the top 4-5 lines rather than just the best move)
1. Morphy vs. Duke of Brunswick (The Opera Game)
https://lichess.org/study/xAo78qLb/truC6WoM
16. Qb8+.
This is viewed as Morphy doing a stylish Queen sacrifice
But if you look at the MultiPV:
Qb8+* leads to forced mate.
Qc3 or Qb7 drops the advantage significantly.
Qb5 actually allows equality
If he had played anything else, he would have been imprecise. It wasn't a gamble
2. D. Byrne vs. Fischer (Game of the Century)
https://lichess.org/study/UZlSqSLA/Ku9M59je
