Highly Evolved Leela reacts beautifully to exchange sac with stunning Qside attack | Sicilian Dragon


Hi all. I have an absolutely fascinating
going to show you .Booot that’s with free O’s Booot 6.3.1 against Leela Neural Network. This is in a TCEC cup so this is
round 16 2019. Time control is thirty minutes with a five second increment per move. The opening book given e4 c5 – the Sicilian Defence – we have a Sicilian dragon a very
exciting chess opening. Bishop e3 here Bishop g7 so Leela playing with the
black pieces. This is the end of the book Bishop g7. Now Booot plays f3 we have
castles Queen d2 knight c6 white castles Queen side this is still a very
theoretical position and now Leela chooses d5. We have Queen e1 this is one
of the major alternatives in the position from the point of view of
human book moves and over the board chess. Another main variation here is e
takes and Knight takes and I’ve even played with the black pieces here on
numerous occasions. This is a very interesting exchange sacrifice by the way and White ignores that usually and this is thought to be an
evenish position. There are chances for both sides. So Queen e1 though. This is a very
popular mainline move. We have be d5 Knight takes bxc6 exd5 Knight
takes d5 Bishop c4 now Bishop e6 King b1 Here there’s a stem game
instead of king b1 Ne4 has been seen before in the game Fabiano Caruana against Mamedov in 2012. Caruana managed to win that game eventually in 76 moves so he
got a good position and eventually managed to win it in 76
moves. The final position was in the endgame so anyway so we’re in good
company as far as over the board stem games. But here king b1 was played this
is still very very good company we’re following still a Magnus Carlsen
game believe it or not. Magnus Carlsen was white against the British
grandmaster Gawain Jones where rook e8 was played Ne4 f5 Ng5
hitting that bishop on e6 and the bishop goes back to c8. Now to my amusement I
found it amusing rather that Queen d7 can you see what white plays on
Queen d7? To my amusement White has an interesting resource here based on d5
can you guess if I give you five seconds to call the video what would you play
with white which is clinically strong? Okay Queen a5 would be possible because
the Queen’s just left giving up the a5 Square and actually it’s kind of useful
to take that opportunity for that a5 to put more pressure on d5 so this is an
awkward configuration for black and in fact White could take off the defensive
e6 bishop and then this would be quite bad for black. So we see this strange-looking
retreat all the way back to c8 but the beauty is funny enough it does keep
control of the a5 square. And in fact here this is also really amusing
in the game of Magnus Carlsen Magnus actually played a howler of a
move here. Magnus Carlsen against Gawain Jones played g4 and we’ve covered this
on this channel. Guess what Gawain Jones played in this position winning a whole
piece if I give you five seconds? Okay Gawain Jones played f4 hitting the bishop
and also interrupting the Knights control. The Knight on g5 is just hanging. Believe it or not Magnus Carlsen played lost that
Bishop on e3 and actually managed to claw his way back into the game. This was
really kind of amazing Magnus took it seems pedantically on a7
you know but the Queen had influence over the Kings side and with the g-file
opened up Magnus started to drum up real concrete
opportunities and eventually managed to win. So yeah black’s King was in big
trouble bang rook takes g7 and Magnus clawed back to a win there. He’s gonna be
taking on e5 and then on e3 after so that was the classic game just
from last year in Wijk aan Zee (Tata Steel) where that howler of a move g4 was played. Booot
played better than Magnus Carlsen from a technical perspective playing h4
supporting that knight so that there’s no f4 for winning a piece in broad daylight.
Leela plays h6 we have Ne4 Bishop e6 so it seems a bit of bureaucracy here
because of having to go back and forward but the point is now that the bishop can
actually play to f7 which means that it’s holding this d5 Knight kind of
securely. Now you might also think isn’t this strange
what about f takes by the way yeah before we look at Bishop e6 if F takes
here then this is celebrating that pin and this position again it’s White’s
doing very well here with that d5 pressure. If black really has to give up
the exchange which is technically the best move this isn’t very good news at
all for black. So d5 is a major issue in this variation generally it seems. It’s
being addressed here bishop b3. We see now Queen c7 so still keeping an eye
on the a5 square. The other amusing thing by the way this
Queen could also pop in to h2 will see in a later variation where h4 might
actually be weak as well as White’s king so the Queen’s are really bouncing
around behind the scenes but just keep an eye – a look on this Queen as well
keep an eye on the Queen as well. So Bf7 we see g4 and you see
that the Queen’s potentially being opened up as well as the bishop if Black
ever gets in e4 and in fact this is the very top priority for
Leela to take and not allow the knight blockade. So nimzowitsch would be proud
that leela perhaps did not allow this blockading move Knight e4. If for example
a4 then either Queen g3 or Knight e4 if Knight e4 white really has a
fantastic grip on the position. This wouldn’t really be a good advert for the
entire variation. White has really got control here and nice pieces. As long as
this bishop is also kept under lock and key from the blockade as well as that
pawn white shouldn’t fear too much here. Also for example Queen g3 yeah but it’s
preferable from my point of view to do use that blockade if it’s possible so
anyway e4 opens up the bishop along that diagonal and shows the real dangers
now potentially black can build up now. We have rook f1 but you’ll have to note
here as I mentioned the Queen has a view on h2 in this position which is not
entirely insignificant. We see a5 Queen f2 rook e7. This would be a blunder
Rab8 allows Na6 by the way forking Queen and rook. Rf8 is
also plausible. White is fine though so rook e7 c3
Rf8 we see queen g1 and the rook goes back Rde1 now King h8 and actually
it’s almost as if Booot loses patience here because black does have the
interesting possibility of taking on e3 at the right time. Booot seems to commit
to Bishop takes d5. Intuitively it would seem doesn’t this weaken White’s King
side doesn’t it weak and fundamentally the light squares? If a move like g5 so
this is a quite a committal decision so let’s have a look at alternatives g5 h5
this position e3 so that pawn is a criminal which should be kept under lock and key if you’re a Nimzovich fan and if it isn’t we see that actually
sometimes the e4 square can be used as a pivot for the rook to go to g4. So for
example like this and look at this. The Queen also on this angle of the game is
pointing at g1 and here is a funny variation with e2 – so after Rxe2
rook g1 so amusements with this e-pawn letting the pieces really attack the
back row in this variation. Fascinating stuff also
okay so Bishop takes d5 that’s the committal decision I started questioning
and here instead of Bishop d4 what about King a1 as an example? Well taking on e3
taking on b3 with Re5 Rf5 and the thing is here black has a lust
to transform this one pawn into two connected passed pawns
if white ever takes. Say white does take we’ve got potential pawn mobility of two
connected passed pawns and this should end up being really nice for black if we
look at this position White is under severe pressure and look at this
diagonal. White is just really doing badly there. Going downhill so anyway
so maybe there’s some insight there for this committal decision why it was
played Bishop takes d5 so we have Bishop takes d5
g5 h5 and now Rf6 – a technically interesting move but of course Leela
doesn’t have to accept this exchange sacrifice and Leela side steps with
King h7. Taking opens up the wrath of the pieces as you might expect so for
example here taking on g6 Black’s King is looking to be dismantled all
sorts of nasties. It doesn’t bear thinking about
if Rf7 again you know Queen take g6 so yeah it’s just ignored King h7 and
White has essentially sealed the King side. However you know if white had
played h5 then of course it’s maybe it’s worth considering g5 to keep the king
side closed. But here this continuation in the game it seems black’s King is
really airtight at the moment. b3 Queen e5 this is really interesting
so getting the unblockade on the e-pawn and then switching back to b8 here is
fascinating. So pinning that pawn on b3 keeping
an eye on this diagonal this b8 to h2 diagonal we see Queen e3. If Bishop e3
a4 and Queen b5 this is interesting for example this endgame the light
square bishop is pretty good and if Black gets the f-file this is just very
good for black. So Queen e3 will see a4 which is very aggressive stuff. What’s
going on here now ? So trying to open up lines against the White King Nxa4
was played. To show some of the dangers here – if King b2 axb3 axb3 and
then the rook can switch to a7 and here just taking on b3 is fantastic for
black. Instead of Kb2 – what if b4 then what I mentioned earlier Queen h2
is actually very handy here hitting h4 hitting a2 will the light square bishop
and of course there’s the thorn pawn as well to factor in. So say rook f2
then taking on h4 so we’ve got the outside passed pawn here. Black’s getting a big advantage so fascinating stuff. Here if Queen f2
taking taking on d4 a3 thorn pawn e3 and this is just really nice for
black as well look at b4 being really weak and then light square bishop just
waiting to come in. So Knight takes a4 but now Leela to play
what does Leela play if I give you five seconds to pause the video? Okay shredding open the lines not against Shredder though – rather than against Booot so Bishop takes b3 a
takes Qxb3. Is Leela kicking the boot in here? So we see
Nb2 now Ra8 yeah this is very strong and perhaps instructive
to the attacking player. Why not you might think the more direct looking rook
b8 with a concrete threat? Well it could be parried and then what is the follow-up?
For example here white seems to be okay controlling that a-file with this
technical looking move Qa3 so a-file is under control with rook
a8 which provides very interesting opportunities now. We see the move c4
looking at this position from a defensive and scientific manner if rook
f2 for example then c5 is strong for example Bishop takes … Bishop x c3
and here Queen a2 check and this is a disaster for white. On c5 if Bishop takes
then just not recapturing but this look at the a file now is lethal
threatening rook a1 checkmate so keeping that knight pinned at the moment and this
is just leading to a disaster – checkmate So c4 was tried wanting the exchange of
Queens. Check King c1 rook b8 now we see Bishop c3 if Re2 as another try then Rb3 hitting the Queen and now
e3. This is strong this is a very strong continuation that’s big advantage
so Bishop c3 was tried. Rb3 We’ve got pins emerging here. Kc2 Reb7 so an absolute pin a relative pin. This rook is a bit
ridiculous on f6. We see Queen c1 and now rook takes c3 check Qb3+
dragging that King out to play. Kd4. On Kd2 then there’s rook
d7 check and black can play this. Bishop takes and Queen f3 is check mate
so we see Kd4 Qg3 another super powerful move not the
direct looking check by any means but it turns out c5 is also pretty ok for black
more than okay perhaps this kind of situation black gains a big advantage
but this is much stronger Qg3 we see rook d1.
There are big threats in this position involving rook d7. So we see a
Rd1. If for example Rh1 c5 check and then here this is a way for white to
get mated as an example. Or rook g1 again the King being so exposed it’s not gonna
end well so okay so rook d1 we see e3
believe it or not Kd3 – e2 check the King’s really getting exposed. Black
getting rid of that pawn and now taking here on f6. Also strong here is rook
takes b2 check with this continuation Qg4 taking the Queen this is
quite good for black because of the two connected passed pawns there. But this is
even stronger. Taking (on f6) and now taking here wins the Queen. If the King
steps back of course then it’s checkmate so this wins the Queen. Nice tactical
sequence. f7 the game actually ended here both engines thought it was all over
basically. More than 10 units advantage if it continued Qe5+ this is a
continuation example where it’s easy for black. The pawns not going anywhere so a
crushing game by Leela on the black side of the sicilian dragon. Following a
really topical stem game. Booot even playing better than Magnus Carlsen from
a technical point of view not blundering a piece. And still losing to a horrible
hack attack on the Kingside. What can you do? Leela’s just too strong. Okay I

Thanks very much and I think I will do a bolt-on for some of the puzzles of
this game. Okay this is the celebration puzzle book of this amazing game Booot
against Leela this is on www.chessworld.net The improve menu puzzle books
you see it’s the latest one added today and let’s have a look now.
So white to play for a clear advantage here. This was a really funny
thing if Queen d7 to consider Queen a5. Maybe this is one of the subtle secrets
of this whole Qe1 variation. To keep the Queen on this diagonal so it can either go here or here but here it’s hitting d5 now black tries to move the
bishop to g8 we can snap that bishop and then take on d5. So very interesting I
thought that one. White to play for a clear advantage here. What was going on here? I wonder it doesn’t ring a bell
immediately g5? I’ll get a hint. Just Knight e4 of
course the blockade positional blockade it was a bit subtle
I think White’s just in control in the position once the bishop is under
lock and key it’s just the positional blockade. It’s not a concrete solution
but White is just standing very well I don’t think White would have too many
concerns here as long as this bishop is shut out of the game White to play for a clear advantage here
I think that’s a weakness in the last move again neglecting a6 that we can
pounce into that one to win the exchange here white play for clear advantage – this is just crashing through on that on that g-file We can do all sorts
here we can play the check and and use the G file so no way would that be
accepted by Leela – that R on f6. Here white play for a clear edge
again just crashing through. Disaster variations for Leela there potentially.
Black to play for a clear advantage here. I thought this was a fun one with Queen h2
check. Was it taking on first there ah
that’s important actually. Now check here. I’m missing the point. Hold on a moment … maybe it was just taking here. Hint …
Now going for the a-file I think we can just take here
and then Bishop x b3 So it is not easy for White to parry that a file. This one with b4 – I think this is the one with Qh2 because we’re
hitting a2 and h4 So this is good news to just play Rf8
and there’s problems for white after tha. Passed pawn there. Now this one – can we just put the pressure on b2? Actually no no no no … trying to lure
the bishop away from this diagonal c5 nope ah this does require accuracy. Maybe
Rb3 key tempo gainer and now I wonder if it’s … yeah quite a
lot precision is needed. Is it this one c5 I’m guessing. Hint … e3 okay and then here
after e3 okay it’s stuff for investigation if you want to check out
the entire puzzle book and get you know to understand why exactly these
sequences are important – and these finesses so I hope you enjoy that as well as part
of the video checking out www.chessworld.net on there improve menu puzzle books okay
thanks very much.

  1. Great game, thank you.

    Here is Magnus Carlsen's blunder against Gawain Jones: https://youtu.be/3vnroBAc99s

  2. " And Magnus just takes the piece pedantically" "Black seeks lustily to convert that pawn to two passed pawns." "Taking opens the wrath of the pieces as you might expect." "All sorts of nasty; it doesn't bear thinking about."

  3. Would these weaker engines like booot still be able to go undefeated vs Magnus and the other super GMs?

  4. anyone have a link to the video he mentioned in the video. the magnus losing a piece and then winning.

  5. Is there a copyright issue with putting the names of the players in the title or on the screen somewhere? Like "Manchester United vs Arsenal." It helps to know which color is who just in case you misspeak during the analysis.

  6. very instructive .. ! could you please post the pgn file of this game or just a link to where to find it on the web? … question goes out for many of your videos … : O )
