How is is that every world champion from 1948-2000 (except Fischer) was Soviet/Russian? Were the soviets running chess gulag camps and injecting kids with experimental big brain drugs? Paying off FIDE? Did the rest of the world not give a single poo poo about chess?

The soviets didn't rack up that much dominance even in ice hockey or anything else they did

there were definitely accusations of soviet players and arbiters conspiring to get their best players all the way to the top. Not knowledgeable enough about decades-old drama to have an opinion on whether it's true but people definitely claimed it

How many professional chess players did each country have? From what I know, Americans had to rely on tournament winnings, grants, and sponsorships, while in the USSR a promising player could get a steady paycheck to keep playing chess.

"Soviet" at that time is also pretty broad, and covers people from Latvia (Tal), Armenia (Petrosian), and Azerbaijan (Kasparov).

I think the problem is that Magnus waited until he lost to Hans to make noise about it. If he'd said immediately upon Hans's admission into the tournament, "I don't want to play this guy, he's a cheater, we're not good at preventing OTB cheating and playing against a suspected cheater is terrible," then I can't imagine who wouldn't be sympathetic to that.

But because he only spoke up after Hans beat him, it made him look like a sore loser and drew too much attention to the question of whether Hans definitively cheated in that particular game, when the real question is whether it's fair to make people play against a guy who might be cheating.

You still need a lot of money to run an ice hockey team. Chess boards are cheap and easily shipped all over the country. Same reason that the Soviets were world leaders in theoretical math/science but more modestly successful in scientific pursuits demanding expensive equipment.

Fischer claimed the Soviets all colluded in the 1962 Candidates to keep him out of the 1963 championship, which is at least partially correct in that they were most likely colluding with each other but not at his expense.

I think the Russian/Soviet dominance of chess from Botvinik through Kasparov was due to

1. they actually cultivated a strong culture of training and competition and produced many really strong players, and
2. it seems like the suspicion was that many Soviet players threw games to each other in the appropriate situations to maximize their numbers in Candidates etc. or help certain players advance or shut out others.

If my understanding of this is wrong, please correct me.

And I'm pretty sure the Soviet era did in fact produce a lot of dominance in specific areas of Olympic sports like weightlifting, wrestling and racking up golds in all kinds of little sports that only require a focus on that sport in funding, training, and/or performance enhancing drugs from the state. Nothing like the near total dominance of chess but that's a unique game where it's hard to replicate those conditions.

The fact that chess only requires a cheap rear end board, pieces, a clock, some books and any weak PC for analysis is key, so any big country that decides to throw a lot of effort and resources into recruiting and training players and sending them to competitions can instantly boost the number of GMs and strong players generally in that country, see Soviet era and now China. If chess catches on culturally in a big country then it can also lead to an explosion of great players such as in India now (no idea the degree of state support and organization for chess there).

The beauty of chess is that an individual genius can arise out of any place and dominate even the most organized national chess Mafia. It happened to be Fischer during the 60s and 70s but by sheer accident instead of any effort by the U.S. to produce a Fischer, the U.S. as a nation and culture, and as a government, is completely indifferent to stuff like chess compared to muscle head sports like American football, unless a genius happens to arise and be competitive for a championship.

Especially with the ability to compete and hone skills online, that kind of talent could arise anywhere now, even out of a small country like Norway.

Just lmao if you unironically think that people would have just taken Magnus's word for it if he brought it up before the tournament. Because firstly, it sounds like he actually did try to bring it up before the tournament, in private with the organizers. Only because that didn't work did he go with this more public route.

And if he did kick up a fuss beforehand? "What evidence do you have? You're just being a big crybaby Magnus, are you afraid to lose ELO to Hans? He didn't cheat against YOU why do you care? What a drama queen over nothing!" And on and on and on.

It's a lose-lose situation either way. The fact that Magnus chose to not stay quiet about it and go for this lose-lose option says something in and of itself. Choosing to play and lose to Hans first at least gives him the leverage to play the victim card.

It’s right. I read the same in the new Fischer bio (awesome, btw). All the big Soviet guys would gang up against Fischer and analyze the position whenever he had an adjournment, which is fine, but certainly made it tougher for him when he only had (I hope I’m remembering right here) Bent Larsen as a second in many of these tournaments. Picturing Tal, smoking late into the night with Petrosian, Spassky, and a bunch of others planning out the next day’s line. :goofy:

The sovs would also intentionally draw against each other to preserve their energies and help ensure sov wins in big events. Botvinnik played a key role in organizing all of this, being a very savvy political operator by many accounts.

There are so many ways. What you'd really want is to consult a magician, but with an accomplice that gets the board state some way (so live transmission, live in the crowd, and that doesn't even admit any active broadcast methods a player might use) it's as simple as a predetermined way of standing. Or a predetermined piece of clothing. Or a predetermined sound in the hall. Or just a thumper sewn into clothing or a shoe (thumpers that evade most metal detectors cost like 200$ on ebay lol).

It is extremely easy to broadcast a few bits of information surreptitiously, which is all you really need to get as a player from an accomplice with access to the board state.

no spectators and no live transmission of board state is a pretty good start for an anti-cheat method since then you need active broadcast and that makes whatever comm device you use way bigger and more cumbersome to use.

I didn't check it with the computer but Ne3 blocks Rb3+, meaning you can't push the king away from the queen.

If you're doing it as a puzzle you can end it after 5.Nd3 Nxd3 6.Qxb7 Nc5+ 7.Qxb3 Nxb3 -+. If that still gives you trouble, I guess it's an opportunity to practice your technique.

Also on the hans engine matching thing.

The way it works is crowd sourcing engine analysis and if his move matches any of the engines top moves it counts it.
It is crowd sourced, but only the top three submitted engines are kept.

Cast_No_Shadow posted:

There is no quality control on the engines used or depth.
Nothing gets excluded for positions with no analysis, but it does prefer higher depth and newer engines once analysis exists from more than three users. So it does automatically increase in quality over time.

Cast_No_Shadow posted:

This means two things.

1. A score can go up (someone uses an engine that says X is the top move when none did before) but never down.
Very much not the case. Many of the Hans 100% games no longer score 100% as the lines in Let's Check have consolidated. So moves that were once present because older engines thought they were the best move, as in possibly the engine that was the latest engine at the time of the game, are no longer present. Less variety in suggested top moves means less matches.

Cast_No_Shadow posted:

2. If someone, for some reason is attracting a lot of attention, their scores will be higher.
No, there is actually a tendency for the scores to drop. The reason for this is clear. Without this attention, it is more likely to be random low depth disagreeing moves in Let's Check. So you may easily have three different preferred lines appearing, so that's three shots the move matches one of them. Once someone gets a lot of attention, suddenly the top three lines will be Stockfish Dev, Stockfish 15, and maybe Leela or older Stockfish or a chessbase engine like Fat Fritz. And with the increased depth the likelihood of it being the same line three times gets much higher, meaning the previous 2nd or 3rd choice moves are no longer a match.

Cast_No_Shadow posted:

Someone dug into one of the 100% games of hans and found that yes, every move was a tip engine line, found by at least 1 of 150 different engines.
No, that's not what happened at all. Someone counted 151 different engines in total was present in the positions looked at in Let's Check. And they counted wrong, because Stockfish 15 was counted many many times because they counted every different ChessBase user using Stockfish 15 as a different engine (which is lightly fair because of different possible UCI settings, but mostly not really).

Every position was compared against three engine lines, not 151 engine lines. People suggesting that people using Let's Check Analysis are cherrypicking engines to get this result are fundamentally misunderstanding the tool and the Let's Check database.

In fact the reason it is not a good tool for cheat detection is that the top moves of engines present when the game was played can get overwritten by newer engines. For example, if Hans played a game when the latest Stockfish was version 10, and would have scored 100% match with Stockfish 10, but now scores 80% against three versions of Stockfish 15, should we say that Hans didn't cheat because that 100% is "really" now a 80%? Of course not.

So an actual anti-cheating tool like this SHOULD actually compare against very many engines because an outlier match against a specific engine may itself reveal something. I saw someone suggest that in one Hans game for example there were a couple of suboptimal moves according to Sf 15 that were preferred by Sf 11.

The ability to have a smart guess as to what engine a suspected cheater is in practice using gives you a great leap forward in comparing their games against a single engine's output. Programmatically producing "If player X is cheating, they are likely using engine Y" is likely something being worked on.

I disagree, this method is only useful for catching trivial cheaters, and honestly isn't very practical at that. Very few engines are robust/stable in their outputs, and in complicated positions will give different output depending on a lot of factors other than the position itself and the engine version. There is no such thing as "this is the top recommendation by stockfish 11" because the result depends on the number of cores used, the depth searched, the amount of memory it is given, whether endgame tablebases are used. And even if you standardize all that, stockfish actually has a stochastic element to it in certain scenarios. On top of all that, if it is using a cloud service then you kind of have to vet the evaluation uploaded by XxSexyChessManxX.

Even if you could solve for this technical element (which nobody has even attempted) the math behind this analysis is seriously flawed, as are the assumptions behind it. Like, no serious statistian would propose something like this without first going through the absolute basics of running it on the complete game history of a lot of players first.

I'm sus of Hans but if this is the best the community has to offer as far as cheat detection then we have a long way to go.

Sub Rosa

Based on what you wrote then there wouldn't be the consolidation across multiple engines of best moves presuming they all have sufficient depth, but there most certainly is. Most improvements to engines have to do with how quickly (meaning low depth) they find the correct move. But not only is there a large amount of consistency in the same engine no matter how many cores or memory, there will also be a very high match at high depth from any post-NNUE stockfish or other NNUE engine.
