Thanks for watching my video! Fun to see these moves happen in a game! Boy it sure takes a lot to coordinate it

[@6ic6ic6ic]

Subbed. I quite enjoyed your process of parsing the rarity. Very succinct. I'll check out more for sure. Ah, well you only have three but they look interesting as well.

[@twhylerm]

@@6ic6ic6icdef do. his other vids are really well done

[@garrethecker4427]

dude amazing video. not to poke holes in your videotoo much but i am not sure 16:08 is a disambiguation. only one bishop could achieve checkmate there, so Bg2# would be sufficient information. perhaps the notation on the sites showed differently in your data, but i would argue that is an error on their part if so. what's interesting then is whether a doubly-disambiguated bishop NO-capture checkmate is possible to occur. it would seem that you could not have a discovered mate for that to be possible, since you would need some other bishop that could achieve the checkmate if moved. maybe there is a square formation or all directly next to each other or some other creative configuration. if so then i would argue THAT would be the "rarest" move in chess, even if it has never happened it would prove less likely to be able to happen imo than the other options. maybe i am wrong though, again great vid and well thought out!

[@3rdEarlRussell]

That was amazing! 🎉 Great video.

[@kyleking7718]

Won’t be “rare” for much longer lol now people will be doing it on purpose might need to make a new video to show the new rarest move😂 it will soon be out dated

17:05 the video "we have to look at several billions more games before we see this happening" meanwhile hikaru "ok boys, we have a job to do"

[@warehousedave7937]

I hope double disambiguation has a long meme life with Hikaru, like "juicer", pushing P, big black center, wooden shield, etc. it just has such a goofy ring to it. "I'm going to double disambiguate him" is new Hikaru lingo for "I'm going to humiliate him"

[@tihomiryanev1839]

N7xd5# was a single disambiguation blunder

[@matthewdoppel8588]

When you have a single disambiguation, look for better.

💀💀💀💀

[@thomasrad5202]

I actually couldn't believe my eyes, he set up the impossible and took with the wrong knight 💀💀💀 his opponent must have been like "this guys trolling, there's no way"

[@Fast__Snail]

16:08 is not disambiguated, since there is only one bishop move that leads to checkmate. Just Bg2# is enough information, because if either of the other two bishops are moved then there is no checkmate.

[@rayan47450]

Thats actually a very good point.

[@fonteinbloem3067]

According to Lichess at least, it’s disambiguated move. It doesn’t matter which one of the 3 moves leads to checkmate, it’s about notating a move. If you notate a move as Bg2#, you gotta choose the correct bishop according to a situation instead of brainlessly moving a piece that’s given in the notation

[@B16Dominoes]

Checkmate happens after the fact. The point is that any of the bishops could move to g2, which doubly disambiguates it. You are correct that bg2# would be enough information, but I think that because the # sign is at the end of the notation, it needs to be specified by the computer which bishop first, before the checkmate.

[@isimo56]

DOUBLE DISAMBIGUATION!!!!!!!!!!!

[@randomnobody8770]

This comment was made on the main channel of the disambiguation video.

[@wyskers1]

Levy ahh title

[@jeromilittle]

Funny how Hikaru can figure out how to get into a double disambigu-mate position so quickly, but can’t figure out which piece should make the final blow. That’s elementary, my dear Watson.

[@larumspectre8641]

he just got tunnel-visioned in the end

Double disambiguation speedrun🙏🏽🙏🏽🙏🏽

[@RMF49]

double-disambiguated bishop-no-capture is now the rarest. requires discovery. superb video btw.

[@Ytremz]

I wasn't expecting to open a chess video and get hyped for a rhurbarb flavoured pizza

[@ScootsMcPoot]

You'd be surprised how well it would work. Depends on how the rhubarb is prepared though. Raw just thrown on wouldn't be cooked and bitter. But a sweet, habenero pickled rhubarb would be delicious on a pizza. You get the 3 s's. Sweet, salty spicey. The sweet will overpower the bitter, the spice balances the sweet, and the salt makes it more savory and flavorful of course. It's not a bad idea. The rhubarb preparation is the biggest factor. But I would think it would need to be a bit spicy to be done right

[@gogy2336]

36:20 rarest move in chess

[@aonutsihasnouith]

Other GMs: I’m going to study hard and rearrange my life to have a chance to improve my rank in the next tournament. Hikaru: double disambiguation goes brr… 😂

[@VigilTheProtogen]

If I were the loser in that game I would say G*G*, GG but it would stand for "goodness* gracious*" with two disambiguations on the G's

[@tf5920]

To lose by one of these moves is the highest level of disrespect. "Oh no, did you just get double disambiguated knight checkmated? That's so embarrassing my god 😭"

[@AlexHein-k5y]

It would take me a life time figure out the set up for these rare moves

[@itz_arif5031]

[@markmasaki1480]

Now Hikaru should try a doubly disambiguate checkmate of some kind in a tournament game and make chess history.

Dude was double double-disambiguated, in back to back games. What a sport, taking two for the team.

[@Mordithas]

wow, I have seen this video already before your video, really liked that you played the moves in real game XD Thank you

[@alejrandom6592]

26:07 don't you love when Hikaru enters the Hikaru state?

[@Matteopotatoe-17]

Hikaru premoving his reaction

[@warehousedave7937]

I think the doubly disambiguated bishop NON-CAPTURE checkmate would be harder for Hikaru to pull off. Would love to see it done.

[@OmgPuppies]

That game between n_markus_n and mauliliusmius looks like markus was deliberately going for a doubly-disambiguated mate too, the way he promotes two pawns to bishops and the middle one to a queen.

New nightmare unlocked: to get double disambiguated

[@Verbalaesthet]

Ah, so that's what you were doing last time I watched. Double dissing people on the Internet.

[@jeanefpraxiadis1128]

Amazing content!

[@infamoushx9869]

Oh, that’s why I watched a video of him trying to do a double disambiguated knight capture checkmate.

[@nonvitaesedscholaediscimus.]

my mind explodes

[@AI-xi4jk]

I was expecting the original video to mention double checkmates. Even though there is no notation AFAIK to say that both pieces give a check and a checkmate it still makes it more unique than a single checkmate. Combining this with double disambiguation move would make it even rarer?! @GMHikaru you have a new challenge! Also we should petition for double checkmate notation because it’s cool and rare.

[@jamieevans5979]

Well, I just spent 5 minutes trying to figure out how you can set up a double discovery, and now my brain hurts.

[@AI-xi4jk]

@@jamieevans5979 haha I didn’t really think it through 🤭. The best I have is a pawn taking something and promoting to a queen at the same time discovering a double mate. Although there can be 3 queens going to pawn promotion square we don’t have to disambiguate the pawn move. I think I’ve convinced myself that it’s not exactly possible if we stick to this notation. The problem is with notation. It’s meant to disambiguate moves. If we see from the engine evaluation point of view of how many squares are attacked, etc then the answer might be different but that makes the question different as well: what’s the rarest position rather than rarest notation. I guess I digress.

[@jamieevans5979]

@AI-xi4jk That's what I was thinking. Rarest position. Yeah a pawn promoting, checking and opening a discovery the same time would do it. It seems like it should be so easy to imagine loads of possibilities, yet my brain still hurts 😆

[@jamieevans5979]

You used the wrong knight hahahahaha. I can't believe you actually set that up and fell on your face on the final move. Unbelievable! 😂 Well done, though!

[@eni1else]

I’d feel so pathetic losing like that. Even the term just sounds like an insult. “Double disambiguation upon you, double disambiguation upon your cow, double disambiguation upon your whole family”

[@ScootsMcPoot]

Hikaru, do you do zoom lessons?

[@dessertstorm7476]

doesnt count because it wasnt on lichess

[@colegieseking5136]

Shouldn’t promotions be included to increase the rarity? Like wouldn’t all of these moves be even more rare if they were also promotions?

[@JuptOfficial]

that would make most of those moves impossible as you cannot get a setup in which it is mate and also a promotion and promotion mates I assume are much less rare then these specific moves

[@keorbats9429]

And now it’s not the rarest move…😢

[@allannortje6440]

Professor what happened between you and Levy ? You use to be AWESOME with the Blindfolded Chess were epic !

[@izzapro1]

If a move has never happened. It cant be the rarest move. Because its not a move at all. So a move happening only once would be the rarest.

[@Mdd099]

It is a move though. It may never have happened, but in theory it is possible. Anyway, the original video addressed this point at the end but Hikaru was speaking over it.
