This EPIC Sacrifice Broke Stockfish... 

Jokes on you, I constantly play moves that the engine doesn’t see as good

I'm kind of impressed by MVL's defensive skills. After these alien looking sacrifices by Wesley, he played almost perfectly and found every best idea, but it was still not enough.

I ran Stockfish 12 for a few hours unattended and it found the move somewhere between depth 41 and depth 52. That's how much it REALLY doesn't want to see this move. Absolutely crazy.

Hey man, GREAT showing at the tournament. Being so far rated below the others, competing with 2 IMs who are now GMs, and the grind of being a youtube/twitch entrepreneur... all that and still won 1, lost 2*, and drew the rest. I am as proud of you as a stranger could be. Seriously, those games were so fun to watch just knowing who was making the moves.

"go play some moves the engine doesn't understand" levy hard baiting for guess the elo content

Levy: “Wesley plays a move the engine doesn’t see!!!” Me: I do that all the time! *laughs in Botez Gambit*

Wesley wanted to get featured on a Guess the Elo episode so badly that he ended up being featured on an episode where Levy shows a brilliant game. Well played, my friend

When i play chess, the engine doesnt understand a single move. That bishop "sacrifice" 23 moves ago was crucial to getting a past pawn and sacrificing the past pawn for a queen promotion on the other side, winning my game against my 600 rated opponent

One of those rare moments when Stockfish is out of stock.

Only this man could be putting out so much great content whilst still trying to get the gm title RESPECT

The one time Levy can say ‘computers don’t understand chess’ and the one episode he doesn’t say it

My games also confuse Stockfish. It does not understand how anyone could play such dumb moves.

I wish we could get an openings video occasionally like the ones he used to do.

"You never try to destroy an entire castle with one horse"- Levy Rozman, Guess the Elo 18 9:09

YO I ran all the moves from the knight sac on to the queen trade through my Stockfish 14 and gave it like 3 minutes in every position. Not only did Wesley attack with only top-engine moves, MVL defended in the most engine-perfect way. Like, even when Levy said that h5 was the most precise defense, Stockfish 14 discards this move after about 30 seconds and suggests bishop takes b5. And MVL found this defense over the board. That is INSANE. And even the continuation, sliding the rook over and trading queens is top engine-level stuff. Unbelievable.

Wesley: Nf6 Computer: “Man! Humans are nasty! We are so bad at chess!” 😉

Nf6+ feels just like the kind of move I would play in a bullet game

Wesley is such a beast in Fisher random, love it. I honestly would love to see him in the future against Carlsen for the World Chess Championship title, I think that would be amazing match!

I have a hard enough time learning to play with the pieces in their original position

Left it on a bit longer, stock 14 finds it after about 30 minutes on my pc at depth 31!!

I’m gonna guess this is Wesley So’s Nf6 before the video even loads

Wesley So: makes a brilliant move that stockfish did not see Stockfish after the move: of course i saw it, i just didnt like it

Gotham: rooks dont jump over the pieces welcome to gotham chess recaps Meanwhile: 3:03 (i know castling normally makes rook jump over the kin but this one looks like the castling didn't happen because the king didn't move)

When going through analysis in a line after one of my games, one move was shown as giving the best advantage, but having actually played it stockfish concidered it a blunder.

i let lichess's stockfish 14 run, left computer, and came back to depth 38 to find that nf6+ was the top engine move, so no, that sacrifice didn't break stockfish, you just had to increase the depth

Massive trade occurs, “so material is completely equal” HOW IS IT ALWAYS COMPLETELY EQUAL IT PISSES ME OFF

Over the years, I've discovered after an opponent's King side castle, getting that middle pawn protecting the big fella away from that second square was worth many a sacrifice. Credit to So for seeing it in a position and time format that doesn't give the players much time for deep levels of thought. That's why I love Bobby's creation. It brings out the visionaries. On a related note, I was watching this live down the cyber hall at "the club" and Maurice nearly coughed up a hairball after seeing it. LOL

You should do more videos on chess 960! I like it when high level chess games don’t have any abstract theory to confuse me.

The RU-vid “bell” has changed my life. Much love Levy.

That's why I like Fisher's chess. You don't have to know lots of theory, the player that played better wins

I let Stockfish 12 to mull on that position for quite a while. After 4.5 billion nodes, depth 46/60, it considers Bc2 the best move, at +2.8. At no point did it suggest Nf6. I then made the Nf6 move and let it analyze that position, and after 1 billion nodes, depth 42/69 , it ended up on +3.8.

I actually found knight f6. Exept i didnt know what to do after, i just thought when you said its an insane move that it would be some sort of check sacrifice and the only available piece was the knight. Lol.

I feel like 960 is breeding grounds for brilliant moves. I wish more people played it.

However, the new Stockfish 15 finds the move almost instantly

I feel so proud of myself for actually considering the first two moves of the tactic, i admit I didn't fully theorize but weakening the kingside pawns for a crushing attack is a big point I've taken from many of Levy's videos

The funny thing is that stockfish not only cant see Nf6, it cant see the following Qh6 neither. It gives Bc2 as the best follow up with +2 eval but after it sees Qh6 it says +5 eval.

I tested out the position at 7:10 where the sacrifice was played with a beta version of Stockfish 15. It found Nf6+ in under a second. Just goes to show how much chess engines still need to improve despite being 3600 ELO.

Engines often can’t understand my moves, sometimes I even win after that

Wesley: * *made A MOVE that engines doesn't understand* * Levy: "What a brilliant move!!!n :POGFACE* Guess the Elo submitters: * *Plays MOVES that engines doesn't not understand* * Levy: "What the hell was that, you 600, Bozo???"

7th day of translating Levy's titles into Neapolitan: "Stu sacrific epic ha rutt Stockfish"

Can't wait till Levy becomes a grandmaster

Levi:36 moves or 18 moves what the difference if you still win. Me with my few brain cells left: Please don't make me think another 18 moves.

Love the reaction of the commentators, shows how true genius leaves mere mortals dumbfounded.

When you predict Nf6 when levy asks even though u have no idea why: Maybe I am a grandmaster

Stockfish 15 : Sacrificing queen at the 5th move, and somehow win the game at the 34th move.

I am already disappointed this game didn't begin with: 1. O-O

7:48 5th of January 2022 here. If you put the position in lichess today it immediately gives Nf6, it shows "cloud depth 36". Some positions are in a database, I suspect, looks like this one made it in.

“so, wesley begins with the move b4” unintentional but brilliant

I break the Engine on the regular, half the time the Engine is probably having an Aneurysm attack when I play

I played a move that engine tells is a blunder, but on the very next move I checkmated the opponent, and that “blunder” move was necessary.

8:30 "dont copy strike me" then nervous laughter 😅 lol

I know of another great example of a sacrifice that Stockfish has a lot of trouble seeing or even understanding, but I can't seem to find the game in which it was played (I know it was Leela as white and she won, but I couldn't find it). It goes as a bishop sacrifice in the Ruy Lopez opening ; the game went 1. e4 e5 2. Nf3 Nc6 3. Bb5 Bc5 (i believe this was the pre-arranged position) 4. c3 Bb6 5. d4 exd4 6. cxd4 Nce7 7. O-O c6 (maybe the move order isn't perfectly right, but you get to that position), in which Leela played 8. d5 with the idea to follow 8... cxb5 with 9. d6 and completely paralyze black's position. If anyone remembers that game, I'd be glad if you could share the reference.

Wesley So be making stockfish rethink. I wonder if the engine can even spot it as brilliant.

I like that engines still work in 960, because only the setup is different , but all the same rules apply after that

grt job levy, pls post recaps of the fide chess olympiad since the format is very confusing and no one does it better than you!! Keep up the gud work, luv your videos

You didn't talk about some engines saying Qh6 was a blunder

I was gonna comment on your Rorschach impression in your previous video (because it was so on point) but boy do I like you Stockfish impressions in that one!! Great energy and vibe in that video!

12:02 is typical GM talk, give this man GM already

Once I saw it, Nf6 actually made sense at first sight, because I was used to giving up pieces to try to exploit dark-square weaknesses with Qh6.

Never clicked this fast in my life... actually, I have, that was Levy's win in the Round Robin event

That Nf6 reminds me of Byrne - Fischer 1963. You expect the knight to go after material in the form of a rook, but instead it collapses the enemy position. Really beautiful.

I feel like the instant I'm out of prep the computer is like ... wtf was that?

The engine saw Nf6, he just didn’t like it

Levy a few days ago when a position never seen arose: "Chess is hard." Levy today: "Here's some stuff where the rules were put in a blender."

Hey Gotham... I'm playing in a OTB tournament at the end of October, and I was wondering, can you explain everything about chess tournaments to someone who is going for the first time.. explain some tournament rules (do you say check out loud when it is check.. can you go grab a smoke if your opponent is thinking for more than 5mins, and similar) and like how is the organization usually... What are you doing between rounds, how do you prepare mid-tournament.. it's a closed county championship .. 30+30sec and it's a swiss tournament.. So I don't know my opponents before the start of the tournament.. Looking forward getting an official rating :D Cheers!

I'm constantly playing moves that the engine doesn't understand

Saw it live the commentators said it was not a good move at first. They were like “what?” 😂

I make moves that engines don’t understand everyday. I think the technical term for them is “blunders”

Fun fact: Wesley So is actually the Fischer Random world champion (also called Chess 960 - or 9LX if you create an unholy union of Roman and Arabic numerals). He beat Magnus Carlsen in the finals in 2019, making it the only championship Magnus doesn't currently hold.

chess 960? didnt know they made tournaments at my elo lvl

The engine never understands my moves, always for worse.

"I like the preposterous like pan to the camera and there's just a knight on f6" *_this description paired with the camera footage made me laugh_*

This game is incredible. I love chess.

GMs * plays the moves that engines could not understand me, 400Elo * plays one move threat that actually hung a piece.

To be honest, I saw that because that is the only move that opens the king too much with the bishop pair and forces to take

This should be a youtube series

Tal is smiling from heaven

Fascinating to see how levy's analysis is on the spot even in another chess variant

Legend says that Stockfish was hospitalized after this game.

1:00 i see what you did there rozman levy

*New video idea for Levy:* Create three or five games (with players of increasing ranks i.e. 700s, 900s, 1200, 1800s etc...) and put them all in move 20 (or any particular move) of a very famous chess game and see how the players play the position! I think it would be really interesting to see the comparisons between playstlyes and the development and implementation of certain tactics and ideas of specific ranks. Then when you've recapped the new games, explain how the original game was played and why it was so famous! I love your content Levy, really enjoying recent videos and going back and watching the old ones (your energy has been off the charts lately). Appreciation and support from the UK 🇬🇧 !

I instantly thought he was gonna go there

Holy shit. Wesley's really out here living in 3020 while I'm still just looking at the board like Confused Unga Bunga

OMG I GOT IT! KNIGHT F6 CHECK! I knew it! Big brain. 7:48

I actually saw the move in question, figuring that opening up the space after the pawn takes the knight would allow for some kind of tricky mating trap, which is funny because I don't usually see those sorts of plays.

I saw another video where engines didn’t understand a mid-board knight sacrifice in some puzzle. Wonder what that’s all about.

I want a engine that plays for an en passent checkmate or draw with as much depth as needed

Lmao Levy trying not to get copyright striked was quite entertaining

6:20 actually Nd4 can be met with Ne7+ and then e3

I play quite a lot of moves that engines don't understand, that's how how I roll baby

11:55 actually what MVL played with Bxb5 is by far better than h5. At depth 38, h5 is +10.49, while Bxb5 is +5.64.

I wonder if there's ever been a case of the reverse where Stockfish thought a move was super winning but didn't see a counter to it.

12:03 levy said 🐿🇮🇹

*moving a piece Engine: I don't understand Me: I also don't

my 800elo ass playing "gangster" moves while the computer laughs at me missing m1

Levy just don't be too alarmed when someone ned 'John Connor' knocks on your door.

Woah holy shit I was considering playing Wesley's knight sacrifice because the queen on that square looks dangerous, i had no idea that it would actually work

That's a Nezhmetdinov move.

I would love to see showcase spotlights of the top 50 active players to get a better sense of the stakes and better engage with the sport.
