It's frankly quite boring to watch chess, unless you understand what is going on - it's not like football, basketball or hockey, where there is dynamic, action, fast-paced play - for us, chess players, it might appear that chess is dynamic and fast-paced, but this is not so for the common viewer. Let's be honest, would you really want to watch a chess game ...

This sort of thing is what the Preface of the Laws of Chess is for: PREFACE The Laws of Chess cannot cover all possible situations that may arise during a game, nor can they regulate all administrative questions. Where cases are not precisely regulated by an Article of the Laws, it should be possible to reach a correct decision by studying ...

According to FIDE's Anti-Doping Policy: The 2018 WADA Prohibited List and Monitoring Program can be found at: http://list.wada-ama.org/ The most relevant banned substances for chess are: • Amphetamines – e.g. Adderall, Ritalin • Ephedrine and Methylephedrine – Prohibited by WADA when its concentration in urine is greater than 10 micrograms ...

First of all I would consider the Preface: The Laws of Chess cannot cover all possible situations that may arise during a game, nor can they regulate all administrative questions. Where cases are not precisely regulated by an Article of the Laws, it should be possible to reach a correct decision by studying analogous situations which are regulated ...

In my thread on the English Chess Forum, which seemed to make the world go crazy on the subject, I gave all the major and minor events in the history of the “legal” triple check that my extensive research has uncovered. This loophole was even talked about recently in Episode 20 of "The Chess Pit" at the 12:13 mark. Here is all information in ...

Sponsorship is more like an investment. For example in video game competitions, companies like 'Sony' and 'Redbull' may invest money, of course, in the hopes that their audience will be more likely to purchase 'Sony' or 'Redbull' products since the players are using them. In your example, I don't see what AlphaZero has to gain from casual enthusiasts by ...

I agree that it would break the FIDE rules against note taking, but this is not a FIDE tournament; it is online blitz on Lichess, so FIDE rules need not apply. You'd have to look at the Lichess terms of service instead. They say Cheating. We define this as using any external assistance to strengthen your knowledge and, or, calculation ability to gain ...

I am not an arbiter, but here's what the rules say: Rule 4.3 (emphasis added) if the player having the move touches on the chessboard, with the intention of moving or capturing I think it should be clear to any reasonable person that picking up a piece that was knocked down by a spectator does not imply intent to move. Perhaps the arbiter went with an ...

You are absolutely allowed to call the arbiter when it is your opponent's turn. There are any number of reasons why this would be necessary. To start with the most prosaic, you have filled your scoresheet and need another one. You are feeling unwell and need medical assistance Your opponent has picked up a piece but isn't sure where to move it to. They are ...

I'm not sure what 'colours reversed' means in this rule. It is really very simple. Suppose you and I are playing in a Swiss tournament. The draw shows that you are to play white against me in the next round. By accident we sit at the board with the black pieces in front of you and the white pieces in front of me and we start our game. We are playing the ...

There are a number of serious things wrong with what you describe: While they are thinking and holding the piece You may hold a captured piece while you think but you may not hold a piece that is part of the current position. Your opponent has a right to a full view of the current position on the board at all times except the second or two it takes you to ...

It would certainly allow for more attacks due to kings being stuck in the center, but fundamentally changing the game, which in a way dumbs it down, is not good. It would be less complex. I also do not want to think that I spent 40 years of my life studying something only to have it changed. I do not want the rug pulled out from under me like that.

So I grab a rook instead. Did I break a rule? No, the FIDE Laws of Chess are very clear. The choice of piece is not decided until it touches the promotion square. In so far as touch move applies to promotion the key is that the promotion must be performed with one hand. That is the same hand must be used to remove the pawn from the board (it does not have ...

Article 11.5 of the FIDE Laws of Chess covers this: It is forbidden to distract or annoy the opponent in any manner whatsoever. This includes unreasonable claims, unreasonable offers of a draw or the introduction of a source of noise into the playing area. If your opponent distracts you in this way and refuses to stop when you ask him then you should ...

Why is there no rule allowing a player to claim a draw in lonely king endgames? For the simple reason that there is no need. If you are the player with the extra material you can offer a draw and be almost guaranteed that your opponent will accept the offer. If you have an opponent who is ignorant of the rules you can walk away and let your clock time ...

Would it be sufficient here to write Ne4+ (meaning Nce4) only (i.e. without the "c" but with "+"), as Nfe4 would not be check? It depends on exactly what you mean by "sufficient". By "normal" definitions of "sufficient" the answer is obviously "yes". "Ne4+" disambiguates and leaves the human reader in no doubt which knight was moved. However it doesn't ...

Bobby Fischer did not resign the title, although it may have looked that way. As the New York Times reported at the time: The International Chess Federation stripped Mr. Fischer of his title and gave it to the challenger, Anatoly Karpov of the Soviet Union, because the 32‐year‐old American failed to meet the deadline for formal acceptance of federation ...

Was playing with both hands ever allowed in chess? Yes, before 1997. Hence in 1995 Kasparov was not breaking the rules. The key article in the the FIDE Laws of Chess is: Article 4: The act of moving the pieces 4.1 Each move must be made with one hand only. This first appeared in the 1997 edition of the FIDE Laws of Chess. The previous edition, ...

In these rook-pawn endgames the key rule is that if the defending king reaches the queening square (h8 in this case) then the game is a draw. If the attacking king manages to control it (but not occupy it), however, then it can be a win. You can see this by looking at the key positions [FEN "7k/8/6KP/8/8/8/8/8 w - - 0 1"] White cannot stop Black ...

According to the FIDE rules, it is not forbidden; clock times are actually explicitly stated as one of the items that a scoresheet may contain. See the following excerpt (emphasis mine): Article 8: The recording of the moves 8.1 a. In the course of play each player is required to record his own moves and those of his opponentin the correct ...

The Candidates will be held in Berlin, Germany, on 10-28 March 2018 (source). According to FIDE's Rules & Regulations for the Candidates Tournament of the FIDE World Championship cycle 2016-2018, the following will qualify, in order of priority: 1. The loser of the previous World Championship Match -- Sergey Karjakin. 2. The 2 finalists of the FIDE ...

It is not prohibited would be the main answer. Caffeine was removed from the list, and moved to the WADA "watch list", so it is not currently banned. "Bupropion, caffeine, nicotine, phenylephrine, phenylpropanolamine, pipradrol, and synephrine: These substances are included in the 2019 Monitoring Program, and are not considered Prohibited Substances."

There is no loophole. Rules 3.7.1 to 3.7.4 allow pawns to move forwards along the same file, or diagonally forwards onto an adjacent file. The only argument here seems to be that "forwards" is not explicitly defined but it is implicitly defined by 3.7.5.1 which beings with the following quote: "When a player, having the move, plays a pawn to the rank ...

Between most players, Elo ratings are zero-sum. The formula for updating an Elo rating looks like this. Suppose player 1 and player 2 are playing a game. First, their ratings are used to generate a prediction: an expected score W that player 1 will get against player 2. Then, we compare this to the actual score, X. player 1 will get K*(X-W) points, where K ...

Yes According to the FIDE Laws of Chess 9.5.3 If the claim is found to be incorrect, the arbiter shall add two minutes to the opponent’s remaining thinking time. Then the game shall continue. If the claim was based on an intended move, this move must be made in accordance with Articles 3 and 4

It is important to realize that chess is a zero-sum game*. In other words, everything that gives advantage to one player gives an equal disadvantage to the other player. So if adding 2 minutes to your opponent's clock benefits you, then it would be harmful to your opponent. It is not possible for any decision of the arbiter to give an advantage to your ...

Fide has a rule saying that if one player is rated more than 400 points higher than his opponent, their difference should be set to 400 when calculating rating gain/loss. That means no matter how weak the opposition is, a GM (or anyone) will receive minimum 0.8 rating points for winning. What is the reason behind this? This is an historical anomaly. ...

Biggest reason? Indecisive games. Hard to make money for sponsors when 60%+ of the time there’s no winner. In a sporting event, no one likes ties. Possible avenues are faster time controls, where at least spectators don’t waste half a day watching no one win. Back in the 19th century Steinitz had match rules that required players to reset the pieces and ...

I suppose what is comes down to is that the way 3.8.2 is written can be argued to have a syntactic ambiguity. 3.8.2 can mean either "This is a move of the king, and either rook of the same colour, along the player’s first rank," or "This is a move of the king and either rook of the same colour along the player’s first rank." There's no ...
