ASMR Chess | Highly Evolved Leela stunningly squeezes & excites Stockfish beautifully in KID


Hi all. I have an absolutely epic chess game to show you today. Neural Network Leela Chess (lc0) playing against the mighty Stockfish. So all games up until this game were all drawn between the two.
With Stockfish leading TCEC Season 15 so 5 draws I believe. And this game
Leela is playing white. We have d4 so Leela ID 41800 and Stockfish as of the 19th
of April version of 19th of April 2019 So we have here Knight f6. The King’s
indian defense has entered into. So the book moves given to both. This is all
book moves the Sämisch King’s Indian. This is named after Friedrich Sämisch who
once lost a lot of games on time in one tournament (but to be fair he was 73 years old!). That was one of the stories and
he’s he’s been involved in other very opening variations like the Sämisch
against the nimzo-indian. So this idea of f3 is very interesting and it’s one
that I’ve used quite a lot as well of great enjoyment so after Bishop e3 like if I am playing against the Sicilian Dragon. You are ruling out the use of the
g4 square from black. You’re preparing simply to create a battery and exchange
off quite often the dark square Bishop to kind of make these dark squares more
vulnerable. So there’s a basic undertone of a crude kind of plan there. And often
castling queenside so it was a one of my favorite systems against the Kings
Indian Defence. We have a6 here being the book given to them still . a6 – there are three
viable alternatives : c5 has been seen before for example this has been seen
before and White is supposed to have a small edge. Knight c6 immediately and it can
transpose into the a6 so this is known. And White has got a
small edge generally. Or e5 immediately encouraging d5 and this
position is quite interesting. White again could have a small edge here. So we have
a6 – it’s a very good move generally Qd2 Nc6 Nge2 Bd7. This is the end of the book given to both of
them. And now we have Nc1. Now Nc1 strengthens White’s control in a way
of the b5 square so if blacks preparing something that
rook b8 and b5 that’s locked down a bit here. It also sometimes means Knight b3
controlling the d4 square which means that if ever black plays e5 white
can react with d5 and have that control of d4. So no Nc1 is a pretty standard
move in this type of position. Knight c1 as an example if whites had castled
Queen side instead then b5 here is actually pretty good for black. Because
a2 is vulnerable here in some of the variations and if Knight d5 this kind of
thing. White might be okay but why give black this counter play and even
worse if C takes then blacks gonna get a big advantage like this kind of thing
with even exf6 possible and then later f5 with not just the diagon pressure but also a-file pressure. This is not the position you want basically you want to minimize black’s
counterplay especially if you’re going to be casting on the Queen side so Leela does
a very good move. Not castling immediately it seems. Nc1 and now black
commits to e5. If rook e8 then as mentioned Nb3 strengthens that
d4 square so any e5 now d5 and unless black wants to just give up that pawn for virtually
nothing then this position in fact the knight is also useful for pushing
through with c5 here with a big positional advantage. So this is the
underminable part of the pawn chain – the most exploitable base and if
d6 goes then e5 is weak and that echoes for a lot of Kings Indian games.
The battle to undermine each other’s pawn chains.
So anyway e5 d5 so e5 immediately Knight d4 and now it’s too dangerous to
take on d4 – black is getting a lot of play and in fact with the King in the center
there might even be really dangerous tactics – this is just giving black you know huge things like Knight takes e4
potentially and then Re8. You wouldn’t think of doing that
basically as White. It would be absurd so basically you want to minimize counterplay
generally and so here after Nd4 the knight goes back to e2 to to challenge
that knight now. Also b3 has been seen before
and White accepting doubled pawns. This kind of thing might also be quite pleasant for
white. There’s still the c5 break and in fact that pawn is now being used for the
c5 operation and that’s plausible as well. But this is this is good as well
Ne2 – now Stockfish played Nxe2 Playing instead c5 for some
dynamic play doesn’t really work. Because dxc6 (en passant) and then take you on d6 is fine for
white to do. There’s no backfire here. So Knight takes e2.
Bishop takes e2 and you can see that white has really good control over b5
here and the possible use of c5. So Knight h5 white does Castle queenside
here. f5 and now King b1. Now I’ve often enjoyed games in this position when you
play King b1 and black ever plays f4 quite then often you can just simply play on
the Queenside because black has released that tension on the center and kind of giving you a free hand on the Queen side and that’s where White has more
space. That’s where the pawn chain points as a general rule where the point pawn
chain points is where you want to build up your pressure and increase your
pressure and open up lines. And it’s on the Queen side in fact if black releases
the tension that the bishop drops back and you can start playing for c5
generally speaking if it was a human game. And for a moment black is not
compelled to play f4 releasing that tension and you might think well isn’t
white foregoing the attacking opportunities that I mentioned earlier
Bishop h6? That’s true but it’s adapting to the position if blacks going to close
up there then ok black has increased King safety but has reduced counter play
in the center when you play the flank attack on the Queen side. So here we see
Knight f6 putting more pressure on e4 so White is kind of tied down to e4 here and
a strengthening move is played – Bishop d3 Stockfish reacts with Queen e7 and you might think – well is taking pausable After Knight takes it gives white really
a comfortable position. This is quite a comfortable position. There’s no real
entry points on the f-file. The bishop is hemmed in by its own pawn on e5. This is
pretty comfortable for white and in fact white could play like h4 and still
actually have an attack. Without the F pawn as a shield the position reverts
now back to the crude elements of the original plan with h5 to take out the
bishop and maybe sacrifice later on the H file. So
that’s really dangerous so black played Queen e7. We have Queen c2 – a really nifty
positional move so Leela is really positively encouraging now with this
pressure this battery on the f5 pawn for black to release the tension. In fact
Stockfish does now release the tension and the question can start to be posed.
Is black being strategically crushed. Is this already positionally becoming
crushing if black has no real play on the King side and is just waiting for
white to build up on the Queen side. It seems a big strategic commitment to play
f4 however F takes e4 as we’ve noted before. This this kind of position white
still now got attacking prospects so and still can play in fact on both sides of
the board in this scenario with with c5 as well as h5 imminent and apparently
a move like Rh3 is very dual purpose not just for h5 but sometimes
switching the rook over to the C file so very flexible rooks in this
position maybe sometimes for both sides amusingly
but White ends up being better basically if if the black rooks are showing flexibility
as well it’s the C pawn which is a big target in this scenario and white could
end up with big advantage just with the C pawn as well and also of course the
bishop is tied down. With this move on this location hitting a5 all time then the
bishop can’t really help that easily as well. So these scenarios
really perhaps encourage black – Stockfish to kind of release the tension – this
free hand is give them for white on the queenside so it’s very interesting if
one could consider this as strategically winning. If black strategically lost
there and in a certain regard. Rab8 and we have King a1 Rfc8. If black
tries to do the active b5 here it seems as though white can play Qb3
and it doesn’t really matter about b4 Na4 but let me just show you bxc4 Qxc4. In this position c7 is attacked and it’s very
very comfortable for white in fact with a move like Bishop c2 and Bishop b3 this
is just really solid for white. With that C file pressure and the Queen side
generally. But also let’s have a look on b5 Qb3. And on b4 it does
seem in some variations as though Knight a4 is playable.And on Qe8 then at least there’s Bishop c2 sometimes and supporting that knight. And
still with c5 so it’s still very comfortable potentially. So anyway Rfc8
– that was an unchecked variation by the way I hope that’s correct. Most
of the variations you’ll find in the annotated PGN so Rfc8 and we have
g4 now here h6 is played on fxg3 hxg3 and this is very good for the
pressure on the King side. And in fact white can still play with c5 here for
example like this and then g4 even. This position is going to be very nice for
white once that c5 goes. Black’s pawn chain is
absolutely wrecked in this scenario. Look at it how diced it is.White has got a big
advantage structurally. It is structurally that often Leela it seems
to be to me World class – the number one in terms of pawn structure and pawn
management. So fxg3 although it seems active it gives
less shield to the king and there’s all to play for for white on both sides of
the board basically. So h6 not taking up that opportunity so g4 really reduces
black’s potential counterplay on the King side as well. h4 Ra8 – it looks as
though the whole Kingside is about to be locked down. If black plays g5 here
then Queen e2 this position is very good for white. This is just a fictional
scenario. White playing for c5 and even d6 because we’ve got tactics now like
Bishop c4 check and taking the queen. E.g. here the Queen is taken. So Nd5 this scenario is just really strong here. There’s tactics again dxc5 Bishop c4
check winning the Queen so there are very favorable scenarios if black plays
g5 so black didn’t commit to g5 as an example. Just Ra8 so Stockfish
is reduced it seems to waiting now. Black cannot play on the King side unless h5 which
is still possible – more plausible than g5 basically. But the Queen side punch c5
seems to be just hanging around here and in fact rook c1 echoes that Queen side
break c5 which one can really prepare and play at the most effective time
possible. Ne2 getting out the way the Queen on c2 is looking at c5 again. We
have h5. Black does do something on the King side. This locks down the King side
now so really this free hand it seems very tempting to just place c5 here. In
fact it’s waited on with Rhd1. You might think that with Rhd1 can’t black “batten down the hatches” (do something about c5). b6 but there’s always potentially things like b4 and c5 anyway
so maybe there’s actually still no hurry for c5. We have Rcb8
Rd2 Queen f7 Knight c3 Bf8 and in fact yeah it looks as
though black is “battening down the hatches”. It look it looks as though you know c5 is really dissuaded now. What is Leela doing? Is this a bit too
casual? The thing is the kingside has been locked out now of the equation. So
if white can totally optimize the c5 break then why not.
And it seems as though if there were two rooks in front of the Queen
this would be called the Alekhine’s gun Is this very useful? Sometimes it is to
double forces as a tactic in its own right – doubling rooks or creating an
Alekhine’s gun is a very powerful tactical construction and here it can
potentially make c5 more effective. We have Ng7 and now night Na4 so
disregarding blacks preparations against c5. White is just building up to c5
even more so we have the knight building up c5 the bishops there. The rooks there
that partial Alekhine’s gun ready to take opportunities on the D file. The
bishop is also ready to swing to c2 if there’s a battery on on the a4 knight. Now
black didn’t bother with Qe8. Black played b5 in this position. If we just
get an idea of Bishop takes a4 which is a kind of sin in a way giving up the
light square bishop because black is already very vulnerable now on the light
squares. Even more so without that bishop this is not what black generally wants to
do. But this plan of b4 would be even more effective if even the Queen’s came
off. This is still white with the bishop pair is going to have a very juicy c5 pawn break coming up. So b5 was played – a slight downside of blacks activity could leave
a weak pawn which could be picked off later potentially. And in fact Leela
doesn’t want to activate black’s rook necessarily so plays just Knight c3
teasing the pawns forward. We have if just as to illustrate you don’t really
want to give the opponent counterplay C takes then this position in fact is
going to be very nice for black as an example. This would be a way of black
getting all the play and that would wreck White’s position so Knight c3 is
important trying to minimize the counter play over here.
Ne8. In this position if b4 here Na4 is possible
supporting c5. It might be on the rim But in this circumstance of Queen
e8 then Bishop c2 – that aforementioned resource Bishop c2 can come to the
rescue there. And still white can play now for c5 – a juicy moment indeed so c5
was played We have Bishop f1 King h8 Qb3
Rb7. On b4 here again Na4 comes into play and if a5 c5 and in this
position White’s getting a big advantage there’s a target c5 and E5 have been
weakened. There’s no backward support no pawns are going to support e5. It has to be pieces how for protecting e5 later as well as you know c7. So these pawns are
major liabilities in this position. So we have rook b7 a3 – and now a very nifty
move indeed and this morning I was looking at my iPhone very early in
the morning and someone was asking about a3 if that just like equalized. And is that throwing away things – what’s the point of a3 it turns out a3 is super nifty. I
thought in some vague abstract sense a3 might support b4 and c5 at some
point but actually in practicality more practical the use of the a2 square for
this route to d5 gives the option of hitting c6 on route to d5 and that is a
very interesting finesse as we’re about to see. So Bishop e7 Rdc2 so
again this build up. What’s happening here? Where is the commitment Na2 is played. so it looks as though now Nb4 to c6 potentially is
dangerous. c6 is played so why did Stockfish commit to c6? If king h7 just
to illustrate now as an example if black just played a waiting move like King h7
Queen c3 cxb5 and now Knight b4 – this position like going into c6
basically dislocates the b5 pawn here. That’s a really juicy target here so for example rook c8 Bishop takes – b5 is
dropping off – it’s dislocated. If Bishop takes Queen takes. It is still dropping. Look at the light square bishop. Black’s bishop is a prisoner inside the pawn chain – an
absolute prisoner if you look at this pawn chain. This is a nightmare there’s
no kingside counterplay. There is no tension in the center. White has got a pure
freedom here, and has dislocated the b5 pawn and that pawn is going to be snapping off here
with a big advantage. So black resorts to c6 just to illustrate this a
little bit more in this variation. So in the Kh7 waiting move variation
let’s go to move thirty-eight here on instead of rook c8 oh we’ve already said
that sorry. So c6 we have dxc6 Bxc6 and now Knight d4 cute
rather than Knight c3 it’s hitting c6 enroute to d5. So white has now got
another thing to play for this – this strategic square d5 doesn’t just have a pawn on it.
It can have a piece a strong piece on it hitting in all directions reducing
blacks counterplay further. Although you could argue with c6 at least this Bishop
is given some light of day that sometimes the bishop can come on this
diagonal but yeah swings and roundabouts let’s see Bishop d7. On Nc7 the
Bishop’s hanging here so has to be moved. We have Qd3 not immediately
going into d5 Queen d3 we have a5 and now the Knight goes into that beautiful
square Knight d5. We have Bishop d8 okay the bishops got some light here it seems.
But now here c5. This undermines the pawn chain. It immediately challenges the
structure weakening e5. That is a pivotal support of the e5 pawn here this
d6 pawn. And also White is breaking through that C file as well Qc3
very nifty now. Not even taking on c5 Qc3 immediately eyeing both c5 and e5
and black defends e5 with Queen g7 and then we have Bishop takes e5. Black is
strategically busted one could argue in this position. Even though the
bishop okay doesn’t entirely miserable we’ll look at white’s pieces by contrast. That
huge knight on d5 we have b4 Qb3 On axb4 this is this will be a
tactical disaster after check. Leela is not going to do
that now – maybe in the past. Queen b3 a4 is played on bxa3 then Queen takes
this. This variation with Bishop c4 shows White dominating the position with that
fantastic knight outpost. The bishops control key entry points like b3.
Everything’s pretty secure here and in fact white can play invasive moves like
this with a big advantage so that’s hitting that rook on a6. Big advantage
it’s very nasty scenarios for black indeed as an illustration. Here
if King h7 a4 and here is an illustration where Knight takes f4
becomes dangerous after Bishop d4 pinning the Queen against King so yeah
black cannot resort to waiting moves with the king. There are horrible things about
to happen on some of these diagonals for example like this and then White crashing
through the D file. So a4 is played. It is a commitment– pawns don’t go back. Is
this going to be a target in the future this a pawn? The Queen goes to d3 bxa3.
Bxa3. The pawn is constrained. It’s blockaded and when we
talk about blockades Aron Nimzovich was a big fan of the blockade. We’re talking
about absolute control not relative control. You know you could control pawns
from afar but if you blockade them you are making it totally illegal for that
fixed target to be moved. It really is a fixed target. It cannot move it’s not just
controlled it’s absolutely controlled so is the a4 pawn a true liability in
this position or not? Let’s see … Rb7 Queen d1 looking at a4 – starting to
look at a4 but also partially an Alekhine’s gun. Because this rook can
swing and we look at the d-file as well and there
could be terrible things with that D file for black in store. Queen f7 rook c5
Queen g7 and now Bishop c4 Raa7 Bishop a2 – where is this Bishop
going? Rb8 R5c3 Rab7 Rd3 Bishop e6 is played here now
white is actually threatening something quite subtle here. I wonder if you can
spot what white is threatening if I gave you five seconds to pause the video.
If white had another move white could play Knight c7 in some variations.
Black played Bishop e6 so for example rook a8 bang wham bang knight c7 here
behold rook takes rook takes and then look Rook takes d7 crashing through
the seventh rank checkmating the Queen. The Queen has no
squares here. It’s been checkmated – the Queen would have to be lost there so
that’s on Ra8. Bishop c8 Nb4 behold the power of the D file. Rook
takes d8 for example here crashing through and then taking and scooping
up loads of material crashing through the 8th rank. Bishop a5 is an example
Knight c7 crushing so rook takes rook takes and then rook takes d7 back to
chat mating the Queen stop fish helpless here so this move Bishop e6 reflects desperate tactical circumstances giving up that pawn. That fixed target the blockaded
pawn the one which was totally under control from the blockade is now
dropping off the board. It’s official Leela is now material up still with a
very dominant position, superior pieces here. We have Bishop d7 if Bishop takes
d5 then that drops the knight here tactically just absolutely losing. So
Bishop d7 protecting the knight. The Queen just drops back so a pawn has been
knocked off blacks position. Is black getting it to be in a
critical state? The light square bishop come off the board. Does this help black?
Black is still a pawn down. It’s the same color bishop here – it’s not even an opposite
colored bishops scenario. We have Queen f7 Rc6 infiltration
and also preparing to double rooks but looking at g6 now laterally. As Aron Nimzovich says – the point of infiltrating on files is to put pressure on
across the ranks from the infiltration squares. Rook a7 Queen c2 we have Knight
g7 rook c8 not minding the exchange of rooks crashing to the eighth rank pinning the
Bishop Raa8 Rxb8 Rxb8 Queen c6 – the Queen is now threatening
things like Queen d6 hitting the loose rook and hitting e5. If e5 drops then f4 is
under scrutiny therefore would be severely weakened. We have Qe6
and in fact this is a very desperate move because there’s still an issue with
e5 in this position. Leela just takes and obliges with the Queen exchange because
now Bishop d6 forking the rook and e5. The rook plays a check to gain a tempo
but it doesn’t help the e5 situation here. Kg8 bishop takes e5 Leela is
now two pawns up. Is this the end of Stockfish here – is this the first
official game in history that a neural network beating stockfish in the main TCEC event season 15. It looks as though Stockfish is in big trouble here. King f7
another pawn bites the dust Knight takes F4 -Stockfish is three pawns down now and it’s not even opposite colored bishops. Bishop e7 King c2 – Ra1
rook d1 the rook goes back Bishop e3. What’s the technique here – is it good
Rd1 Ra4 Kd3 Rb4 Bishop d4 holding B2. Rb3 Check. The bishop drops back. White surely can just push these pawns now. Ra1
coming for that a-file rank to put lateral pressure if needed. F4 – the
pawns start being pushed – f5 rook f1 the rook doesn’t use the F-file.
It comes back here. The King comes in. Kc4 f6 these pawns look absolutely huge. e5 – black desperate to blockade them to no avail.
It seems hopeless. Check and the game ended here. Both engines reached the magic threshold
for an auto declaration – an auto adjudication. Black basically lost now
this game because it based on the evaluations of both engines being above
ten I believe now. As a sample continuation king d3 Bishop c5 rook a8
is strong with the idea check and then e6 and in fact the bishop could be put back
in prison and white can casually play for e7. So this could be a scenario – a
fantastic win. This is a historic day in neural network chess history. This is a
historically important game in my view. I hope you enjoyed it as much as me. If you

  1. Q. Can Neural Networks do ASMR style chess games with Squeeze and Excitation networks ? 🤔😀😎🌍 Video: http://bit.ly/2ZG568z

    Replayable game: http://bit.ly/2vxXlE9

    #chess #chessgame #ArtificialIntelligence #AI #MachineLearning #DeepLearning #lc0 #Stockfish

  2. Very well commentated. In the last 5 minutes, I thought I was watching a boxing match. Yes, a historic win for Leela indeed!

  3. For anyone wondering the title, "Squeeze & Excitation" is a new technique used in the Leela T40 nets. It provides roughly +50% increase in capacity with only a small slowdown.

  4. Fascinating game, relentless. Not seeing all the games, still one observation: in the last few games there were no spectacular sacrifices by Leela, leading to pieces of the opponent being locked up in an insignificant corner of the board, nor are there stiffling thorn pawns. Are Leela's opponents getting aware of the lingering dangers, are we seeing both players getting even better, where the winning strategies become more subtle, beyond human grasp? Somehow the last few games look more normal to me, deceivingly so, the strength hidden behind these normal looking moves. Are we heading towards uneventful draws, where the only adventurous games are to be seen where there is a huge enough difference in playing strength?

  5. You confused me alot today in this video. I appreciate the video but your explanation a couple times was contradictory

  6. Very exciting play by play explanation of possible scenarios, but more importantly the actual game itself is an epic event. It reminds me of hockey announcers when they go into a verbal frenzy just before a hockey star player scores the winning goal, at the last minute to break a tie game. HE SHOOTS HE SCORES!!!.. and the crowd goes into a maniacal state of mind. N.B. I'm from Canada but I suppose in the British Isles soccer elicits similar emotions. Bravo kingcrusher !!!

  7. Did not appreciate the raised voice in the last five making the event sound dramatic – next you'll be telling Leela is human…

  8. am very much a stockfish fan, but also a good sport…congrats to Leela on the win and an excellent job by Mr. Gavriel on the annotatioins!! good work!!

  9. Its funny becouse looks like leela knows it was a win since the very beginning and stockfish didn't know since the very ending. I remember by memory something like 15 points evaluation to Leela and 1 to stockfish with the same material. Nice game to see live and better now with KC analisys.

  10. High-Level Shuffling. This is what human GMs most of the time don't do long enough to optimize & increase whatever small advantage they managed to conceive. Also, about the last 5 minutes of the video felt very much like a football game. Nice commenting.

  11. This was fun; I enjoy the 20-30min Leela videos a lot. Kingscrusher was like a hockey announcer toward the end, so maybe I wouldn't describe it as asmr, ha.

  12. For reasons that are not entirely clear, chess engines don't particularly like the King's Indian and White scores very well in King's Indian games from the TCEC. People do somewhat better with the black pieces against each other in such variations. It might be that at the highest level, the King's Indian is not as reliable as some of the more solid defenses to the queen's pawn.

  13. The excitement from KC's voice during the last part of the video like a football match being commentated on lol.

  14. Thanks KC – I really like that.
    Those closed positions are usually what I became involved in during tournaments.
    How to break down a closed position and gain control is very difficult to do.
    Those 2 White Bishops on the a file were crushing.
    It meant that Black just didn't have any good moves.
    This seemed like a real human game as humans would play.
    AI is copying us but playing better.
