My read on the situation is that Magnus had two goals: 1) remain world champion 2) get to 2900 elo #1 got in the way of #2 because all the elite grandmasters constantly focus throughout the year on preparing for Magnus, which creates a headwind in the non-world champion tournaments where he must perform well to reach 2900. My guess is he will focus on 2900. Then, come back as world champion. Then, retire after 7 cham…

My read is he's being honest and will not in fact enjoy playing the World Championship.

Chess on an 8x8 board is not NP-hard. That doesn't mean it's easy but invoking NP-hardness is kind of meaningless.

Like parent was saying - that is true of all problems in practise since the earth has finite resources. That doesn't make complexity classes a useless concept. In other news, no point in needing pi, because perfect circles dont actually exist in the real world.

I don't think people are trying to claim it's unimportant in general, to anyone, they're suggesting that it's completely unimportant in this conversation about how slow and boring championship chess matches are.

Unless I missed something recent, it is not known whether any player has a winning strategy (or a drawing strategy, for that matter). It would be quite the discovery as well.

Having a winning strategy for black seems impossible though; the discussion is whether white have it or is it a forced draw.

Why would that seem impossible? One could argue that white has to open up his defenses first, allowing black to pick the best response to that.

In general, there’s no guarantee of first mover’s advantage. For example, Hexapawn (https://en.wikipedia.org/wiki/Hexapawn) is a win for black on some boards (https://web.archive.org/web/20050330222720/http://www.chessv...). Versions that are more complex than chess and are a win for black may exist.

How would point ratio help if every game is a draw? Maybe if it was a round robin tournament that would help top two players competing for wins against less highly rated people and then drawing against each other. Like Liverpool and Man City

My feel is that from a game theoretical approach, a 3:1:0 scoring ratio would encourage enough players to at least try for a win sometimes that it would restore some of the interest and competitiveness to the sport.

Would you play tic-tac-toe for a win with that scoring ratio?

Funny that they mention Arkady Dvorkovich, I would expect him to quietly retreat from managing current affairs in FIDE because of his high position in Russian civil service. How can one of the closest allies of Putin head an international organisation nowadays?

In March he condemned the invasion of Ukraine and stepped down from his other positions (which have not included working for the Russian state since 2018). You can always say he should go further, that he's tainted by his past links to Putin, or point out that if he had really turned on Putin he would have found polonium in his tea by now, but it's misleading to describe him today as "one of the closest allies of Put…

Isn't he still the Chairman of the Board of Russian Railways, a state-owned company?

> And against Nepo it was a steamroll, understandably meeting him again isn't that exciting. The first half of the match wasn't even close to a steamroll. It's just Ian broke mentally after that famous 6th game. The candidate tournament showed that he had more than recovered from that loss and I think he would be in a much better shape to challenge Carlsen again. Also, with Carlsen's current attitude, it is quite pos…

nepo at candidates was in my opinion favored to beat magnus...he dominated the candidates harder than anyone else has in the history of the candidate matches - and it was not an easy pool of candidates, either. Sure, there were a lot of sloppy games, but only a couple vs nepo - with one of them being after the 1st place spot had been guaranteed. If nepo plays like he did in the candidates, I would not be so quick to…

What about Fischer? The format was a little different then, but here was his route to the Championship.

1. Won the Interzonal tournament 18.5/23 (+15-1=7). The top 8 from the Interzonal then played a knockout series of matches using a bracket system.

2. In his quarter-final match of that he beat Taimanov 6-0.

3. In his semi-final match against Larsen he also won 6-0.

4. In his final match against former world champion Tigran Petrosian, he won 6.5-2.5 (+5-1=3).

In the 21 games total that his candidates matches lasted, he won 17 games, lost 1, and drew 3. If we include the Interzonal it is 32 wins, 2 loses, 10 draws. In the combined Interzonal and knockout matches he had a streak of 20 consecutive wins against the world's top players.

And then in the Championship against Spassky he won 12.5-8.5 (+7-3=11) (and one of those loses was a forfeit when he skipped the game over some complaint about the playing conditions).

Nepo's performance in this Candidates was pretty dominating, but doesn't come anywhere near Fischer's level of dominance.

I think he had issues with the challenger selection process. That's why he was willing to play if it was Firouzja but isn't interested in a rematch with Nepo.

And I think pretty much everyone predicted that had Naka won Magnus would play.

Does it count as 'breaking' if you're just tired of the game and don't want to play any more? Surely it's OK to stop and do other things eventually?

Yes, that's what people mean, almost by definition. In highly competitive events, even a slight break in focus and drive toward winning are often really problematic. Once that wolf-like focus and readiness to fight is broken, a competitor is usually done.

Depends on the game, but people will often come back much stronger after a ~6 months break.

It’s a mix of having a new perspective, dealing with stress, and having time to heal etc. This is one of the reasons most sports have an off season. Even if basketball could easily be played year round, the game would suffer.

Time to change the format. It's understandable you don't want to spend your whole career preparing for these long matches all the time. For the challenger it's 6 months of preparing, but for Carlsen it would've been his 6th time of preparing for this in a few years. They have also become less entertaining. 12 matches is long (edit, 14 now), but no one dares to take any risks. Caruana was just defensive and all games…

Chess' centre of gravity is increasingly online centred now. Carlson himself has a lot to do with it. So do other charismatic super GMs like Nakamura. A light hearted, unplanned and unadvertised naka-carlsen bullet match can attract a lot of viewers. They both stream, and lots of other chess streamers will switch to watching and doing commentary when these matches happen. They'll play silly openings like the double b…

I've thought for a while that someone should go hard on an esports style lightning tournament. Basically, try to recreate the energy that happens when an aggressive game happens between chess hustlers and everyone crowds around, but done as a stadium audience spectacle like esports. Big stage lighting setup, music, live commentary, crowd roar encouraged, etc. Besides a main event focused on rated pros, have side tournaments and exhibition games with big personalities. I think there's definitely a sizable audience for something like this.

Stockfish won't solve it. We need a full game tree. Stockfish is not designed to build a full game tree. Generating a full game tree would be a truly daunting undertaking, and I can't even fathom how much memory would it take.

Due to alpha-beta cutoffs, you don't need a full game tree. But if you did build a tree with all legal chess positions, it would have approximately 4.8x10^44 of them [1]. [1] https://github.com/tromp/ChessPositionRanking
