another rule is that you cannot capture your own pieces chatGPT did that a lot of times

They should add a piece called the Prince. You don't start with it, it can only be obtained through promotion. It moves like a king and a knight. If you have a prince you're allowed to leave your king in check. If your king is captured the prince becomes a king.

9:45 that's actually mate

now explain why the thumbnail move is illegal

There was a legal move back in the day in which you could promote your own pawn to an opponent's piece

The reason why en passant was created was because originally pawns only were allowed to move one square.. but to speed up games they let pawns move two squares and made it so they can still be taken but only on the next turn... Changed the game a tiny bit because originally you were not forced to capture on the next move if the pawn moved the one space... Should be as long as the en passant can be played it should be allowed...

You forgot "dea dei cavalli" which is where a pawn freshly promoted to a queen can also move like a knight, but only to check the king and only on the turn which it promotes. It's also known as "il grazioso pony rosa della principessa" or "la bellissima principessa pony rosa."

abaut 18th rule : originally the peices were even ofter black and red

You said the illegal move rule twice to make the video longer

One thing was forgotten: On promoting a pawn on the first or 8th rank, the exchange to any piece is allowed, except a king or remaining a pawn. You can thus promote your pawn to a piece of your opponent’s colour, theoretically checkmating your own king. It’s called the Japanese kamikaze promotion. It took place for the first time in 1964 between Tal and Fischer in Tokyo. Hence the name.

1:26 Wesley forgot the rules 7:50 Magnus crushes the opponents defense

"draw by insufficient material" can actually means 2 different things. USA: if you cannot force a checkmate. Rest of the World: if a checkmate is impossible. The only difference is King + 2 knights vs King. You cannot force a checkmate, but there exists checkmate positions.

Il vaticano is not a real chess move, just like the double fianchetto opening (which my friend always plays with people who don't really know the rules, consisting on moving both you b and g pawn to b3 and g3 in one move)

Very nice video! I'm really enjoying these videos!❤️ I have a small correction though, there is a penalty for an incorrect 3 fold repetition, usually the arbiter adds time to the opponent.

Actually you CAN change the target position of your piece from one target tile to another as long as you DID NOT RELEASE the grab of the piece. Also, I've seen arbiters accepting adjusting touch as ok even without announcement if it's obvious that it was just adjusting, e.g. if the piece was obviously crossing two or more tiles so it wasn't clear where it is or the knight was not facing forward and the tough was not a full grabbing+holding+picking kind of touch. These things can be distracting in deep concentration.

9:44 is not a draw, but a checkmate

Stunning video, thank you for the basic tutorial of chess, we loved it

Out of "Il vaticano" and the loss of the match for illegal move all rules stated in this video actually exist, however the loss of a match because of the illegal move is not directly stated in the FIDE laws of chess and will be treated as any other illegal move. Il vaticano doesn't exist at all

Question, is it legal to castle on an under promote rook across the board in opponent castle?

I started to invent my own chess variant and so far the only rule change i had was no switching sides between games but you gave me so much inspiration for rules to add to my version of chess weather it’s tournament exclusive or general rules for all basic versions

You forgot to mention that it’s allowed to say “adjust” “compongo” or any language reference to adjust a piece so it’s not considered touched before moving

you had me with the vaticano

How to do the Bishop move special?

To add to your list: a player cannot "pass" their move. They are required to move even if all of their available moves are disadvantageous. aka the player that wants to pass is "in zugzwang" Also, a lot of amateur players aren't aware that you can "under-promote" a pawn instead of changing it for a queen at the end of the board. This is useful in niche cases such as when getting a queen would create an immediate stalemate, or when a knight could be used to deliver an immediate checkmate or king/queen fork to rescue a position. (and you can't leave it as a pawn or make yourself a second king) Adding a little history - the pawns didn't used to be able to move 2 squares on their first move. when that rule was added (to speed up the games), en passant was added along with it, to prevent players from abusing it to get around their opponent's pawns. Another rule (tradition?) that I think belongs here is one player holds a piece (king usually?) of each color in closed hands and the opponent picks a hand. that hand is opened, revealing the color that the picker gets to play Of course in tournaments, they take turns, but this is how who gets white and gets to go first is traditionally determined. Thanks for the video - I did learn a few new things. Namely, that the triple-repetition draw need not be sequential, that the 50 move rep can be declined, and I didn't know the 75 rep rule existed.

we should have more meme moves, like my example, Belagarung der letzten rang (using online translators so it might not be accurate) siege on the last rank. where if a black rook is on the 2nd rank, or a white rook is on the 7th rank and for black another black piece is on the same file but 3rd rank and white same file but 6th rank, the 3rd/6th rank piece can catapult over its respective rook, but as soon as that's done the rook is turned upside down to note that it has been jumped over.

Does the one hand rule apply when performing El Vaticano ? Sounds difficult to execute.

Corrections/errata: Castling: 1) you also can’t castle into check, either. 2) you must move the king first. Talking: 1) You can also call checkmate, since it is - by definition - a check, which you can call. I don’t know if there’s a penalty for calling checkmate if it’s not really checkmate. 2) You can say, “I adjust” (or the French equivalent) on your move. This indicates that you’re just repositioning the pieces closer to the center of the square they’re on, not that you’re moving that piece, thus, the “you touch it, you move it” rule doesn’t apply. 😊

3:16 I never heard about chess having turns, do you maybe mean moves? I.e. if white played, for example, 16.d4, then black can play 16...exd3, as it's the same "move"/turn, but it's illegal for White to play 20.gxh6 after 19...h5, as it's the different turn/move? It's really confusing, as I play chess for over 25 years and I never heard anyone speaking in terms of "turns". Can you explain what the "turn" in chess is? Thanks! 🙂

im a chessplayer by one year and the last one got me laughing

Your explanation of 3-fold repetition is wrong. I must be the same position with the same available moves (castling, en-passent). What do you think, ist he difference between an illegal move and a wrong move?

Anyone know if you can resign if you have king and pawn vs king (where you have the extra pawn) in a theoretical draw to force a draw if your opponent refuses to accept rather that letting your clock run out or playing to stalemate

Lol, I was going to lose it at “IL Vaticano.” Seriously though you actually did a good job explaining touch move, and how announcing adjust or j’adoube excuses it

I just looked up IL Vaticano and it said it is not a valid rule

So, lighter color pieces move first, but what if you have a set with bright blue and neon orange pieces of the exact same brightness? What happens then?

The 50 and 72 rule should be changed as in our time there positions that need more than 50 or 72 moves to win, example with 2 knights and some pawns as it forces mate, with our days computers the machine should tell what the number or moves needed so why they don’t change it if I not mistaken it needed 82 as seen in some games, yea it not happen often but it should be this rule.

#10 is misleading. The King cannot pass through check is stated correctly, but then incorrectly adds "on any file between the King and Rook", but those squares nearest the Rook do not count.

Promotion to pieces other than queen is another relatively obscure one.

I tryed paying the last rule on a computer and it diden,t work😂

Man missed Qh1 😢 mate in 1 7:00 and reasons like these is why stockfish makes me get so many misses😂

7:53 That’s a loophole right there.

Is Il Vaticano fake or do you need to take two pawns who already captured via en pessant?

We always wondered: WHAT IF you promote a pawn on the e file for a rook, and your king hasn't moved; can you castle with that vertically or does the rule state that it HAS to be horizontally with one of the original rooks?

Just for completness: There are three types of casteling. The short casteling to the king side rook, long casteling to the queen side rook and an extra long casteling to a rook on the e file. For the last mentioned option a pawn has to be promoted on the e file to a rook and must not be moved as well as the king. If there is no check and the square in front of the king is not under the opponent's controle, all conditions for this extra long casteling move are obsereved. For white the king moves to e3 and the rook to e2.

For castling and attacks that are cutting it off.. it’s actually the path the king moves through and not the rook itself

rule 10: correction, you can't castle if one of the square where the king go is controled by the opponent piece. it is more clear if castle on the Queen side, the king move two squares, only if on of the two squares is controled, then you can't castle. if it is the square next to the rook that is controled by the opponent, then you can castle.

Imagine if you can mate in 1 opponent but he moved his pawn allowing for il vaticano. A hard choice if i was honest.

The last move is not a real one.

7:30 did the guy in the background just capture a piece on the white square with a queen on a black square????

8:00 That is not a rule. In a standard game, the position prior to the illegal move would be reinstated and the opponent would be penalized, the fact that you made a move is irrelevant. In a rapid or a blitz game, you have forfeited your right to claim the opponent's illegal move, but as long as the move itself was legal, you will not be punished and the game will continue, unless both players agree to correct the move without any intervention of the arbiter. I have no idea how the arbiter was thinking in the Carlsen-Inarkiev incident and the chief arbiter of course overturned the decision as it was based on a nonexistent rule. Also, intentionaly making a move to gain an unfair advantage would probably get you forfeited for bringing the game of chess into disrepute.

Very good video. One important thing that you missed is that the 3 fold repetition is not just visual position. It has to be EXACTLY the same. For example, if I moved a tower from its starting point and then back to its place, then you can say it is the same visual position than before. BUT! Before that move, I was able to castle and now I can't, so it doesn't count as the same position and it can not be counted for the 3 fold repetition. This also aplies, for example, if the same visual position is repeated but the player's turn is different. You can not count thay as a repetition because it isn't the same game position, even if it is the same visually.

In my opinion, I think that the rules should be like an on and off switch, where both players decide if they want a certain rule or not eg, the touch rule

The IL VATICANO is probably a meme for sure otherwise why can' we play it on the analysis board

i once had a 52 point advantage and tried to get a position for memes, and it caused a draw by 50 move rule on move 152 lol

I have never heard about several of these rules. are you sure you didn't make them up?

I love how 3:20 and 3:23 are both Hikaru but one says when you play it on new chess players and he’s rubbing his hands and the next one says the look and their faces and again he’s looking confused after apparently just playing it himself 😂😂😂

You should be precise about the explanation of rule #10. Castling through check. You had said if they control "any square in between the king and rook". That is true for casting short/king side. However, in a long castle scenario, if your opponent controls the square immediatly to the right of the queen's rook, the king may still castle, since it's not passing through that square. Better to phrase it that If an opponent's piece controls a square that the King would need to pass through or land on, it's not permitted. Cheers.

I had no clue what il vaticano was Thanks

Genuinely thought il Vaticano was a real move for a second til I looked it up

you forgot the draw rule “timeout vs insufficient material”

9:45 this is not a draw...

Well done. The only reason I watched this entire video was to hear about a rule that isn't actually a rule.

in thailand first rule is really fun because most thai peoples don't know about this and rate every chess game 1star

The stock footage at 6 made an illegale move, queen from a black square diagonaly to a white square

Do we have to say check loudly when giving a check

Petition to make a B-O-O-B move legal cause it looks fun

7:30 stock footage capture looks very wrong to me. x)

5:02 I don't do either, I grab the king, use it to slide the rook to it's place, then set my king in it's place

I know all of them except il vaticano

My friend knew en passant existed but didnt know what it was so when i did it to him he was like OOOOOOOOOOOOOH THATS WHAT IT IS

my favorite move. #1 "IL VATICANO"! LOL

Is vaticano a meme or next one?????

De todos os 20, eu só não conhecia o 5, o 2 e o 1.

A few things. 1. You can checkmate by en passant, even a forced one. 2. You can checkmate by your king and 1 knight if your opponent has a pawn. It would be a smothered one in a corner with your king blocking the exit one way and the knight above the pawn. 3. You can checkmate by castling also. It is extremely rare and never has been done in a tournament game. All conditions apply. 4. You can get a smothered checkmate while having only 1 or 2 pieces besides your king and being down by more than 10 or more point material. It is rare and hard. 5. You didn’t mention opposition and the ability to have tempo in pawn and king end games via the opponent king. Otherwise great video. Knew all the rules. 5.

Note that stalemate has nothing to do with the king as such, other than his inability to move into check. Indeed, there are ways to stalemate without the king being able to move even into check.

Number one was new to me

The double hand move I's stupid like what is it even going to achieve doesn't mattter much either

Vertical castling though,

number 6 for me castle then king makes more sense for me bocouse castle can move 2 spaces lagally king not (in any other moves)

"Talking on the board" ... yeah, tell that to the chess pigeons in the park

As I'm sure some have pointed out that example you put as draw by insufficient material was a checkmate...major fail

3:03 white is winning jf he plays Ke2 but we all know en passent is forced

Funny joke, I was already typing! Well done, you got me!

Now i know how to preform B-O-O-B, Thanks!

You forgot the crossaint move where you can promote a horse to a queen and the queen can teleport

El vaticano is new to me

2:00 I've never heard that!

Someone claimed it is a draw if only the king can be moved after fifteen moves. True or false? TY

Number 10,you put a king shadow instead of a queen

All the years I played chess I didn't know that one about the two bishops and the two pawns

0:22 why is this stalemate?

Cool

Thanks i have a chess tournament

10:42 that bishop on the left looks very sus

5:48 "queen" *proceeds to show a king*

When he said in the starting ! Abt the bishop move which he told in the last it is joke 😢 I literally watch the whole video for that 😢😢😢😢😢😢 PEOPLE LIKE ME LIKE! 🤙

Il vaticano is the only rule i didnt kniw

The most important rule is missing..... We have seen up there very nice rules + definitions, incl. stalemate. But what is a mate?! My definition is that "this is such a state (position) when the one king is in check and in the same time this check cannot be covered by any pawn or piece of king's color and the king itself has no legal moves (i.e. each potential move - if any - of the king lands on a square where it is under check again). In that situation the player who gave its opponent such a check - wins the game!"...... :) Perhaps it worth to mention another rule too - it says that ALL moves in the game should be done within the provided time interval, i.e. should no reason for finishing the game (there are many such reasons - see the video above) appear, incl. a mate (check-mate) and time of one of opponents runs away - he loses the game by time while the other opponent wins the game by time!!! :) :) :) Of course, the "time rule" varied over years and centuries, but nowadays - it is basically as described in this comment here :) :) :)

#19 @1:16 neither king is in check, they are both one move off being in check

Oops! You made a slight mistake, or just said the rule not precisely. In queen-side castling the rook may pass through a square held by the opponent.

You can slap your opponent if he slaps you first.. but no harder than he slaps you
