This was a great video randomly suggested in my feed, keep up the great chess content Croissant!

and he sacrificed... HIS ELO AND SANITY !!

Carl Magnussen is crazy

what about en passant checkmate? like if you want him to lose his sanity and go to therapy beacause of this🤣🤣

That elo drop was deeper than the Mariana Trench.

Carlsen Magnus is probably the best player ever.

Why does that look like a creeper checkmate....

This achievement and the rare king checkmate achievement (discover checkmate with the king) are both achievable with the famous historical game "the perfect king hunt" by Edward Lasker, but not at the same time obviously… He could either move the king up check mate or long castle check mate

En passant checkmate or oponeent self checkmate by force you move

This is such a well made and super nicely edited video! definitely subscribed. thank you for such high quality content!

I apparently got this achievement roughly a year ago, and didn't even know how hard it is. I bet i couldn't do it again if I tried haha. Great video!

The fact that he was willing to lose so many rating points for an achievement, and content, is astonishing. I'm subbing rn

Bro, keep making these achievments walkthrough, they are gonna be useful for a lot of players. Amazing Content

Hadn't seen your channel pop up in my recommended until today, but I'm not disappointed!

100 rated chess, but you have to deliver a mate by castling. Hold up, wrong channel.

"carlsen magnus"

You are absolutly crazy man I love it

I saw this video and didn't think anything of it and never thought for a second I could achieve this feat, until yesterday. Halfway through the game the 1400+ elo lost his queen and I hadn't castled so I thought I'd give it a go. Happy to say I can now say I'm a member of this very prestigious club! Great video and thanks for the inspiration.

Yo you're so underrated dude. Love watching ur vids keep it up :D

You’re playing the wrong opening to get the achievement fast. I got it playing the nimzo where the queen side knight comes out then you push queen pawn 2 spaces, get the bishop out then king side knight and king pawn 1 space to get the other bishop out. This allows you to be able to castle to either side. Also there’s some tricky lines in the nimzo which forces the opponent to castle queen side which puts you and them in the position to be able to castle into mate.

I actually got recently an short castles mate,but before he made a move he lost on time.

Very underrated channel... Keep it up!!!

great job croissant

Ouch, good job with this one

Bro sacrificed his elo💀

From ivy, out middle, through our connecter like a speed demon

I managed to do it once as well. The engine told me "moving the rook was the best"

This randomly popped up in my feed AND I LOVE IT

I got that challenge 6 months ago. I didn’t even know it was rare until I saw your Vid. Thanks!

Strategy: Lower your elo so much that you are just so much better than your opponent that he has no chance to prevent da ROOK mate

I got a queenside castle mate on acident once on a 3 min blitz game on lichess lol.

I just got a Castle Checkmate today, and I got it and realized I could also get "Killer King" with the same position

That was probably the most expensive achievement ever.

Loved this video! Good stuff man!

Bro went from 1619 to 849 just for us, MAD RESPECT BRO

I just got this achievement a few minutes ago. I was so scared my opponent would resign before mate but they were a good sport

I love seeing underrated youtubers

In my lifetime, i've done almost 10* castle victories.

Only one more to go… en passant the forbidden checkmate…

Cleary an underated SACRIFICE!!

our thrift store chess master, carlos magnes

You: losing your sanity and elo to win by castle me: playing a game vs my friend and asking him to lose to castle

really love the commentary and the editing, any chance you could get a camera on yourself when you talk? think that'd bring your videos to 100 fs

Ah yes, the famous creeper checkmate

and he sacrificed.. THE CHANCE TO PASSANT HIM

eric rosen is the master of castle checkmates

Your welcome, Crossaint. You gave me emothional damage by castle mating me. Atleast people can see my loss on your channel

mating someone with a castle is crazy… title made me think it’d be a smothered mate where pawn=knight# or an en passant mate

Respect dawg

I had to subscribe out of sheer respect.

ah yes, carl magnusen

Ok, now do a short castle checkmate. Jk, nice video and good luck recovering your sanity after this xd

Good. Now it's time for en passat mate! (Anyways there should be an achievement for that aswell)

Hey, what is that sound effect on 0:06?

Well done

I somehow have this achievement but realised it was rare only after watching this video

Great video

what’s the song playing during the final match called? anyone know

If you play enough online, you'll get some really cool positions. Closest I got to this one was a Qside castle check, but that's not really rare.

5 mates in a row by mates with a pawn if op resigns you have to start over

I did a king move checkmate about a year or so back and i didn’t realize until right after that i could’ve castle mated him instead. Damn im kicking myself now knowing that the achievement it’s soo rare.

it happened in one Gotham vid where a cheater got mated by long castle 😂

Try to keep the queen and king together during the whole game and also castle checkmate. Plus, I castled checkmate just now with martin.

en passient, or however you spell it, you got to get a checkmate with it

Crazy coincidence how i on the day this video was uploaded got a textbook queen sac smothered mate in an over the board tournament

Bro is doing side quests in chess

just thinking does puzzles also give the castle victory achievement

Mad respect 🫡

My friend checked me with a castle during a real game, and it drove me INSANE

I actually got this castle checkmate some weeks ago! GG on getting this rare achievement :) (I didn't even know that It was that rare???? Is it actually that rare :0)

And he is not a coward.

I spent like 20 minutes and missed 30 mates in one with some random stranger but I actually have this as well

This is the "How did we get here" of chess 😮

technically this is sandbagging

"Carl Magnusson" 🤣🤣🤣🤣 Come on that is obviously Mango Kahlsen

You EARNED a sub

That's a really cool way to do that

You didn't en passant when the opportunity was given, so I am therefore invalidating your attempt Joking, or am I? Great vid

The opponent is like why did he resign ??

I checkmated my opponent by castling 3 times, 2 times from opening staford gambit and 1 time from traxler counterattack, Eric Rosen has also video How he did that from staford and also mamaged to do that from Traxler (it was always long-castle, short is probably imposible :D)

Does it count if you castle and then they resign right after?

Sandbagging on main and posting evidence of it is wild.

4:22 ...Q×f2+ would've been HILARIOUS to see. Black sacrificing the Queen just to ruin White's whole day.

just checked and turns out i apparently got a castling checkmate on July 2 2023

How about a double checkmate by **two pieces which have never left their starting squares** (and don't leave it on the last move)? E.g. given "2N5/1pK5/k7/P7/8/8/4P3/R4B2 w - - 0 1", assuming White's rook and bishop have never moved, 1. e4 would force 1...b5, allowing 2. axb6#, with neither of the pieces attacking Black's king having ever moved during the entire game.

Fun fact: I once missed castle checkmate because i was too focused on skewering the king to the queen with my bishop. that ruined my day. but seriously, bro should of played en passant and let tacotacio play e5 (only move) then castle checkmate.

Cant believe he played the cow opening

fair play!!

Man, i kind of want to see the climb back to 1600 lol

Cagnus Marlsen

Carl magnsun 🐐

When this channel will pop off, will you remember to play a blitz game with me?

Cool. Now do the vertical castling checkmate. (Yes, I know it's sadly no longer legal... 😢)

In that last game you blundered en passant, you got the achievement, but at what price?

Bro is really underated

Me: makes my friend help

As a person with one en passant checkmate, i cannot relate

Oh, so you were the silent spectator i played against on stream. GG :)

Bro you are like the rekrap2 of chess how does you only have 5k subs

i say that chekmating with en passant is way more impressive but cool video btw
