Chess Master plays RAREST CHESS MOVE to defeat computer

[paralogical-dev]

Nicely done, thanks for sharing my video! It really takes some maneuvering, doesn't it? And I must say, I really like your mouse cursor!

[zaszz]

Statistics nerds hate this one weird move

[sage]

the video is skewing the data already indeed

[paulrobbins]

Jerry, you truly are one in 342 billion. Well done!

[moose]

Amazing. I just watched the Paralogical video yesterday and now this. Been watching for many years. Appreciate all you do Mr. Network :)

Not only was it a doubly disambiguated bishop capture checkmate, it was a doubly disambiguated bishop capture *discover* checkmate.

Batman: Robin, old chum, Chester the Chester is threatening to capture the queen! Run the Batfish analyzer.

Robin: Holy double disambiguation Batman! Three bishops of the same color!

[michaelf]

Now play a doubly disambiguated knight capture checkmate for good measure!

[JSYantiss]

Could you still have written "Bxc5#", since the e3 Bishop is the only one that could deliver the mate?

[Ralyx]

Congratulations, now that you accomplished it, it is no longer the rarest move! Task failed successfully!

[tolkienfan]

Ok, I accept that's a very rare move indeed

[flippert]

Haha, my silly level 1 brain thought "ok, rarest move must be bishop underpromotion", but that is actually just the prerequisite for the actual rarest move.

The introduction did an incredible job explaining the video and got me excited to watch all the way to the end. Nice job!

[jono]

I had just seen the paralogical video as well, and I was so excited to see you address the challenge and then do it. Nice job Jerry!

Normies: “Hm, what can I do to calculate another move deep?”

Jerry: “Hm, what can I do to make chess history?”

[mwhale]

Can you still say it was an ambiguous bishop move requiring that extra notation since only 1 of the 3 bishop captures would result in checkmate? I feel like the true challenge is that any 3 bishop capture would result in checkmate justifying the notation

[MJR_ATX]

Challenge: stalemate with as many pieces still on the board as possible

[jerkasmo]

Jerry there was an easier way I think. For example at say around 12:00 you're having trouble finding 3 pawns to promote to dark square bishops with a dark square pawn. Instead you could put the black king "close" to stalemate/zugzwang in the corner with only 2 squares to shuffle back and forth, and then place any piece on the d2 square before playing pawn d4 to offer it up to the black pawn. If the black pawn doesn't take and shuffles the king, then put the king in stalemate until the pawn takes and moves to moves to d3 and becomes a light square black pawn. You then get to promote 3 light square bishops which is much easier to do b/c you already have 2 pawns on the left side of the board promoting to light.

Just watched that video yesterday. Awesome to see how it's done, and you didn't even break a sweat under time pressure. Well done.

The visuals are great. The cartoonish style is not only appropriate for the silliness of the video, but I also find it similar to Paralogical's style (cursor especially)
