The Double DisambigYouWhat??? The Rarest Chess Move!! 

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.

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

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!

That was amazing! 🎉 Great video.

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

🤣🤣😂😂

When you have a single disambiguation, look for better.

💀💀💀💀

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"

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

Levy ahh title

he just got tunnel-visioned in the end

im gonna touch u 🙏🙏🤣

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

Thats actually a very good point.

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

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.

Technically there is enough information for it to be not disambiguated, but standard chess notation disambiguates checks/captures/checkmates like this anyway for convenience.

rip your comment got stolen :(

In the description it says it was posted on the 2nd channel but with far less subs, it seems we should've posted it on main because it got a lot of views.

@@GMHikaruhikaru premove this response 😭🙏

They double disambiguated the video

@@GMHikaru How???

@@GMHikaruShould've been posted sooner then

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

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

@@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.

@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 😆

Both Hikaru and Levy took an IQ test forever ago and they both scored 102 I think.

​@@AlienBrospretty sure Hikaru is trolling and doesn't actually believe that

You can force this frequently

You will have to define what you mean by "Normal move"

@@okaydetar821I guess moving a piece without capturing or promoting or checking.

@@ScootsMcPootIt's not so easy unless you attack the knight with a pawn and all other 5 escape squares are unavailable. I think.

Actually I remember Aronian did this in a classical game once against Firouzja. Very exciting game, one of my favorites.
