This is the wonderful type of video that accidentally destroys the data it was based on, as this will encourage people to try and be the first person (on Lichess) to do a doubly disambiguated bishop capture checkmate.

i watched this entire thing without realising it was made 30 minutes ago because this feels like a youtube classic that shows up every once in a while and everyone loves them

edit: we hit 100 replies, and im leaving this here as a disclaimer. if you ever reply to this saying "hurr durrr the video isnt 30 minutes old" i KNOW. comments AGE. not every comment was posted the minute you read it, so help me god

Hikaru played both "doubly disambiguated bishop capture checkmate" & "doubly disambiguated knight capture checkmate" against a random in blitz just after watching this video. Very cool

[chessplayer]

The rarest move is me not blundering in bullet

[devilbob]

Wait, hear me out!
"Doubly disambiguated bishop non-capture *stalemate* "

[Leenomacino]

I feel like this is gonna randomly be recommended to people like 5 years later. If that is the case, I want someone to reply to this comment at 16 of September 2029, exactly 5 years later

the right hand bandaged after getting struck by lightning is such a nice detail

[cheeselord]

I feel like the data after this video will forever skewed by people wanting to hunt for rare moves by working with friends

[gharren]

Technically, we could add promotion itself to the complication. So bxa8=Q# would be a capturing pawn move with a queen promotion that causes checkmate.

After watching your video, videos without the hands seem weirdly unexpressive

Amount of doubly disambiguated bishop capture checkmates after this video: 📈📈📈

14:48
Obviously someone who watched this video will intentionally do that very soon, if not already done.

[Maou]

See, the thing is, Eric Rosen is probably gonna see this and go hunting (given Rosen trophies)

[ChessNetwork]

This is one really professional chess video. Just fantastic!
I give it the rare notation A++.😎

[typha]

Now everyone will probably get on lichess and try to play games with doubly disambiguated bishop/knight capture checkmates, so I predict that in short order the bishop non-capture variety will become rarest :P

ok an insane amount of love and care went into this video, and into details that almost NO ONE would ever notice. check this out. at 11:25 he actually can't add anymore lines to this list without overlapping with the little data box graphic. but instead of the obvious option of just having the box fade out or slide off screen or something, the box vanishes while it is hidden behind the image coming on screen at 11:32! that was such an unnecessary detail that he went out of his way to do!!

I love the little detail of the hand having a little bandage after getting struck by lightning

[bigman-ujxy]

I love how humble this is as if it isn’t one of the most epic data analyses in all of chess history

[SmartGamer]

Just wait until all of these numbers spike after this…

I'm still amazed by the simple yet genius idea and the perfet execution of those cute little hand animations
