I've really been enjoying this series of videos on Leela Chess Zero (and the earlier ones on AlphaZero too) - and yes, I think I do learn something from each one. :) Thanks Jerry!

[@isteinsvik5995]

What about a game with Leela winning as black? ;)

[@lukechavhunduka2970]

Øistein Søvik check out Kingscusher he did a video where she beat stockfish 9 with the black pieces

[@Narrowcros]

It's an it not a she, and that was Stockfish 6. it doesn't stand a chance against stockfish 9 or 10,calculations are way too deep for it.

[@Cscuile]

I second that fburton8

[@mrgm_carlsen3379]

13:18 nice hax 😉

[@freshrockpapa-e7799]

Mr GM_Carlsen lol thanks for pointing it out

[@ginoginoh]

You can move the bishop like that if you are a GM

[@jercki72]

@@ginoginoh or Justin Bieber

[@sooooooooDark]

14:28 i think leela did that so the white king/queen could see each other a last time before the war thickened

[@JimmyJJJohnson]

Beautiful 😂

[@blindmoonbeaver1658]

[@JB_inks]

13:21 - I know Leela is brilliant but even I'd be impressed if she could move her bishop like that!

[@Maxisokol]

13:18 - that black bishop boldly attacking the king on a white square cracked me up for some reason. xD

[@shaikriyaz1874]

This is sensational, really. Excellent work by Jerry as usual, which we have grown accustomed with

[@truthcrackers]

Delivered with your usual clarity. Keep making videos!

[@Nagaros]

Please continue with these highly instructive games !

[@rmendeljacobs2832]

13:25 Nice arrow drawing for the bishop 😂😂😂

[@irlrp]

hahahaa i almost died

[@JWalkLance]

Jerry, I absolutely love your analysis and commentary style - the best IMO. Many thanks for your excellent videos.

[@collinstump9706]

For the viewers who may be confused, you must be a GM to move a bishop like that @13:20 Another great video, Thanks Jerry!

[@abelhutten4532]

Really enjoying the frequency and quality of these videos! Thanks Jerry, keep it up :)

[@mohd1nagyyyyy]

I am a simple man. I see Jerry and leela together I press like.

[@MrRishik123]

one of my OTPs Leela x Jerry fanfiction needs to exist.

[@pyro-is-magic8202]

From watching Leela and Alpha Zero, I feel like there is some big possibilities in strategies involving killing the opponents Bishops by messing with their pawn structure. That Bishop sacrifice killed the entire Queen side of Black’s board. Maybe one day we could see more GMs emulate this in their play. Anyways thank you always for the great content Jerry.

[@TheJungleRobot]

The way these engines do it require SO much calculation though, I don't think a human brain is even capable of calculating so many lines at once. But yeah, I wish it was possible too cause it makes for amazing games!

[@TheJungleRobot]

Thinking of it, Levon Aronian actually played a game that was somewhat reminiscent of this where he gave up the exchange and a pawn to just isolate the black queen out of the game. It ended in a draw, but that was a beautiful showcase aswell

[@ChessNetwork]

The play is certainly an eye opener. Thank you

[@AScentOfPhoenix]

This is what is known as a "positional sacrifice." Great job by Leela, and an excellent job presenting and analyzing this game by the uploader.

[@fluxvital]

i really love the leela sacrificial strategy. We already seen this in others games from leela and this impress me every time. Thoses games are extremly instructives. Please keep it going

[@LthiagoR]

I came up with Bc4 not 'cause I understood the move, but because it was the most incredible and a little bit intuitive move. Thanks for the video Jerry!!

[@michelemeriggi]

Now when i blunder my bishop in bullet i can say im as good as leela (;

[@lilalexbmx]

Great game. Great commentary. Great production quality.

[@rohith.prabakar]

I did get the BC4 move. Reason 1 - I guessed that it was probably a sacrifice. 2 - I remember Anand Aronian game 2013 had a similar move. It was a just a blind guess tho. Great video as always!

[@scorchedBoard]

Alpha0 used to crush the light square bishop, but leela0 crushed the entire queenside pieces!! So aggressive..

[@marcusklaas4088]

Jerry. I love these Leela Chess videos. Really fresh strategies and insights. I find that Leela and Alpha Zero in particular do a really good job at evaluating positions where they are down piece-wise, but the opposing pieces do not contribute.

[@rmendeljacobs2832]

I guessed the bishop move but I had no idea *why* it would be a good move. It just looked so ridiculous so I chose it 😂

[@quazzydiscman]

Ninnifier O.o, me too. Only because of the title of the video and seeing that revealed check by black's Bishop, I'm like "yeah, that's something a human would never do I'll bet it's Bc4..."

[@Bennerboi]

I saw it instantly, and I was like: "It's probably Bc4, I have no clue why it's good, but it probably is." It's so funny, because a lot of the time I see a really deep great move, but then I don't see the continuation that makes it a good move lol.

[@GEM4sta]

BeEJayLetsPlay Yeah, I'd say 50% of my losses are me spotting a deep sacrifice, haha. Who has time to read lines? Let's see if it works

[@mikem720]

No human as white would be able to convert without some luck, after bishop to c4. Black is going to be able to trade the position down in a human vs human game.

[@idklol2566]

Same

[@yusufceylan5144]

Great analysis Jerry, thank you so much !

[@ChessNetwork]

Thank you Yusuf.

[@GabrielGarcia-ni1qi]

Love the breakdowns or potential thought process for the game on uncertain or unforeseen moves throughout. Awesome video! Just subbed your channel 👍

[@Taubenschmied]

Funny, when you said 'I wonder how many of you are gonna come up with this', Bc4 was the first move that came to my mind. However, I did not see white's pawn move as a follow-up. I only saw Bc4 dxc4 Qxc4+ Be6, so I abandoned the thought. Great video as always, Jerry, you are doing such a fine work by all these analyses! (This is just one of the many ways this comment could have ended, pick your favourite one.)

[@Moronvideos1940]

You are an excellent commentator and analyzer Thanks a lot.

[@haikuaday8253]

instructive as always, jerry. Thanks for these!

[@sheikmohamedamanulaa3898]

A great promo like description for this video.....great effort and good commentary following u from 1 k subs........

[@eldritch43]

Seems like leela is already above human level. Im especially impressed by the way it plays in. Its much easier to follow the game then any other classical chess software. There seems to be a motif and a clear theme permeating and its play. Referred to as "human like moves" by some people. Thanks for making these videos Jerry by the way :) thumbs up

[@ima7mad]

Great content you’re makin lately Jerry. Keep it up, and I did actually predict the bc4 move.

[@ChessNetwork]

Nice 😊

[@TheMarksT]

Absolutely unbelievable Bishop sac there, yet also very reasonable of course, afterwards. Very deep and creative programming this Leela Zero

[@JoeBruin96]

[@zarion1181]

That is very poetic. Nice!

[@adeptsang]

Super cool analysis. This was instructive

[@Fatalotti]

I came up with the Bc4 move, but only because I saw that the black c pawn could be pushed with check, and I realized that sacrificing the bishop there could stop that advance. However, I did not come close to working out the rest of the calculations.

[@uprite88]

Nice pick of games, Jerry! which leads to moves never even considered.

[@liammargetts]

Loving the daily uploads!

[@irlrp]

I love that you showed small opening traps that us, mortals, could easily fall in, but those computers are WAYYYYYY ahead of those moves and explaining them would be irrelevant in this "4000 elo" context I learned so much (i'm a "beginner", i mean, i play chess regurarly but i was oblivious to the opening traps you showed)

[@chrisrichardson3206]

No way I saw bishop c4 😂 I definitely learned a lot from this game. Love your videos Jerry!

[@mradeelmalik]

Even before you're asking about pop quiz, i was thinking the same to sacrifice white bishop. Recently watching so many games of Leela and my game strategy also change from defense to attack. Great Game and Great Analysis.

[@ChessNetwork]

Nice! 😎

[@lawdogwales5921]

21 Bc4!! If that was played by a world champion in a title match it would go down as one of the greatest moves in chess history.

[@durimkid_9362]

Thanks Jerry!! Much love

[@liam314]

Thanks Jerri, love this series 👍

[@trevorrogers95]

Jerry, you rock. Thanks again, man.

[@AnlamK]

Great video as always. And the quiz before Bc4 - I must say great trolling...

[@XIIchiron78]

This was a really cool game. I always learn a lot from these!

[@KF1]

This was great! More games like this, please

[@Flo-vc9wu]

13:28 i like the pressure from the dark square bishop 😂 I guess that was a tiny mistake jerry :D Still very enjoyable video of course

[@IPichu777]

You mean an inaccuracy?! This is chess after all, inaccuracies are going to happen eventually

[@fdllicks]

that was a fascinating video. The bishop sacrifice for positional gain. WOW

[@ulbsualbrykya7141]

a mistake by Stockfish 6 in this game was after b4 by leela, sf6 replied with c5-c4. Evaluation was +1.82 at depth 33. a5 should've been played in reply to b4

[@maxlisk80]

Schliemann briefly rose from grave and applauded this game

[@kapilhanwat2940]

At 7:37 After f5 d* c4 can white still continue with sacrifice and ignore bishop on e6

[@echoes6092]

I'm looking at this again two years later and I still didn't find Bc4. Wow. What a move!

[@scalethemachine]

Nice game. Interesting to ponder the mystery moves!

[@GNU_Linux_for_good]

13:27 *c3 - g8* is *not* a diagonal for the bishop as shown..

[@thehair9236]

16:35 can't stickfish release the pressure and go into a decent endgame with bxd5? If rxe7 rxe7 bxf6 rg7. If bxg7 kxg7 and black has a rook and 2 bishops for the queen.

[@cptnavman]

At 15:30min, why wouldn't Black move B-7 and pin the rooks?

[@LionHGH]

It's crazy watching you analyze a bullet game that's played better than two super GMs in classical time format.

[@edgarrust5605]

why does not black give back the piece? 11:32 Bc8-Bf6 problem solved. pieces get activated and pon due is killed

[@andrewweakland9197]

Still come back and watch this, one of the nastiest games I’ve ever seen

[@Dundee1]

Very in depth and teaching, detailed to every grain, but i cant watch the whole thing without being on 1.5 speed as my only criticism is how some sections of explanation are drawn out although you teach me a lot.

[@YAMI-co8fq]

I'm jealous of your warm clear confident friendly voice.

[@djayel4039]

13:27 what is up with that bishop line?

[@petergregory7199]

21 bc4 is a stunner. Blew my socks off! Leela doesn’t mess about. Especially when she’s playing chess.

[@Adam-hj1hc]

At just over the 5 min mark when the discussion is regarding if the dark square bishops were exchanged, how should white recapture -> pawn or rook.. it has has to be pawn. For the reason Jerry said, but also, if you took with the rook, you would simply be dropping the f4 pawn, no?

[@leyubar1]

18:34 Correction: "Even if there were." Subjunctive mood.

[@fautismus5993]

Jesus m8 you're just the man at any rager aren't you?

[@sciencetube4574]

I was actually thinking about Bc4 because I was looking for a way to defend against the discovered check and to disrupt the black passed pawns at the same time. And because you were saying stuff like "you will never guess this move", I was looking for crazy ways to do that. No chance I could have seen whether it was a good move, though, and no chance I would have ever even considered it while playing a game. This is a "you get it because you know it's a special move" type move.

[@ChessNetwork]

Well said ST 😊

[@peterhavord5984]

A recurring theme in some games for Leela and Alpha Zero is the way they go about paralysing some of their opponents pieces in the same way that Karpov did in some of his more famous games. However, Karpov seldom played the deep strategic sacrifices that Leela and Alpha Zero play.

[@reshad8570]

I came up with that wild bishop move when I watched this video for the second time! Wow! I must be really good at this!

[@GreaterJan]

9:40 What about b4?

[@grandmasterofthrow6238]

Hi Jerry, this is everyone: We love you, Jerry!

[@mcbain7392]

I did not saw the sacrifice, f5 or Kh1 were my main moves :'c . At 14:28 after Kf2 Rb8 white plays Kf1 because sees Ba7 as a thread and the f1 square seems safe for the white king.

[@NantucketSlim]

Finally figured out the Bishop move at 13:30. Awesome!!

[@TranscendentalTunes]

One of the most beautiful bishop sacrifices ever! Makes so much sense - if Black gets his pawns rolling it's game over for White. Makes sense, but not easy to find

[@mynameis1261]

I think, in such situations it is important to look through possibilities of black side to return gained material in order to avoid problems they faces in the game. For example, take one of the e-f white's pawns by black bishop. Anyway this piece almost useless, so black could do this. This "counter-sacrafice" can be done in different ways, some of them should be discussed But anyway, video is great as always, thank you :)

[@bradc3402]

What an insanely deep move (B-c4). These AI's have an amazing ability to make these crazy sacs to put the opponent in an almost zewswang position. Amazing how they can calculate that the extra material is more then made up for in the opponent having all their pieces tied down. Very impressive chess!

[@natfrey6503]

More Leela reviews, please. Really mind-blowing chess games from "her."

[@peterpetrov6522]

Wowzers! Bc4! This type of sacrifice is out of this world!

[@user-sm4mj7ug9x]

Found Bc4. Had to block the discovered check and force pawn takeback. However, i was thinking queen recaptures w/check then going after the knight w/f5. But when i saw knight takes e5 i stopped calculating as i realized the pawn duo was just too powerful to break up.

[@ErikZoltan]

During the video I was wondering if Black could counter with the similar idea 22...Be6?! based on the same thinking as White's move 21.Bc4

[@devonstein7464]

I just have to wonder what prevented Stockfish from sacking a bishop on e6. Seems the only way to break the tension.

[@teslathejolteon8007]

Amazing game! Thank you for sharing it.

[@mrsommer84]

14:27 The reason of Kf2, Kf1. Kf2: White has all the time in the world, so he prepares a liiiittle bit for the endgame. Kf1: He wants to prevent Ba7+ with sudden tactics for Black. And he can't go to e2, or doesn't want, because of B:e6 fe Q:e6+, a sudden sacrifice. These are my guesses.

[@dkevans]

13:30 With only the f pawn defending the e pawn, as black I'd be inclined to sacrifice my white Bishop by playing 31. ...Bxe6 (assuming the pawn recaptures) to give me more space to work with.

[@dodobirdcreations]

Can someone explain why did the sacrifice enable white to advance the 2 pawns? Couldn't white advance the pawns without the sacrifice?

[@PaladinswordSaurfang]

At 1:05, why not 1. Bxc6 bxc6 2. Nxf6, then black either loses a pawn or severely weakens his kingside.

[@ryanpittel1829]

The latest Stockfish development version seems to think that 30... c4 is a mistake and better was bxa4 with a flat 0.00, while c4 leads to a +1.3 for white.

[@tobelli]

Could you please explain the difference between Leela and generic engines?

[@papashirt]

that was thrilling, thank you!

[@SvetoslavBatsoev]

Great game, and great analysis, thanks.

[@ChessNetwork]

Thank you Svetoslav.

[@V8SupersQirreL]

What a quiz at 6:30! No one would play like this!

[@sava-lakicevic]

I had stockfish 8 running on the side, it needs a minute to realise how good the moves from Leela are, it sometimes showed her losing, and then changing the evaluation to ~0, or from losing to winning even. Amazing what Leela has shown us. I wanna see AlphaZero vs Leela!

[@sarahbeanTX]

Savva Lakichevich and Leela had 1 minute for the whole game.

[@ekshimokawa]

Jerry. Thanks for this instructive game. Why Stockfish 6 didn't take Bb7 at 14:20?

[@ekshimokawa]

I have figured out. Rd7, Qf7, Qh7# quick path.

[@benjaminmiddaugh2729]

I wonder if Leela's king maneuver near the end is to get the king out of striking range of the bishops while taking advantage of Black's lack of room to move. (No need to get there directly when Black is bottled up like that.)

[@Akash_ACash]

For me, it was between h3 and Bc4. First, there isn't really a great prophylactic king move or blocking move for the inevitable c4+. Playing h3 would allow Kh1 next, since it prevents Nxh2 (cannot be captured without h3 due to Qh4+). On the other hand, Bc4 blocks c4 directly, attacks the pinned d-pawn, and sets up the f5 advance as mentioned in the video. In my opinion, it's pretty close between the two moves - I think either is playable with a slight advantage for white.

[@IvarHuisman]

These vids are fun thank you!

[@iracole8350]

How did Leela win on move 46 if black made the last move? Did Stockfish play H5 then immediately surrender before white could respond?
