(This video is a game from Leela Chess aka lc0 project - a Neural Network Self Learning AI). Hi all I have an absolutely magnificent
trolling game of Leela chess to show you
today so Leela was playing against Chiron
in the Blitz Battle
Five minutes with a two second
increment in the chess com blitz Cup
2018. So 1.d4 from Leela no trolling
so far but this gets quite amusing
pretty soon actually. 2.c4 e6 3.Knight c3 we
have the Tarrasch defense cxd4 exd4
Knight f3 knight c6 and now trolling
Leela plays not not the most popular move
maybe she hasn't discovered that yet in
training but plays dxc5.  I think
she's just laughing at us humans because
this happens to be a remarkable game
in Chessbase livebook.  Wesley So vs. Varuzhan Akobian which was a default win for
Varuzhan because Wesley had made some notes
on his score sheet so there's a
historical context here D takes c5. The
more standard move is g3 for example
this position - this this variation has
been seen in a lot of games in the
Tarrasch where white plays for the c5
square by taking on c6 and tries to lock
that c5 square and it's thought to be about
equal chances actually. But dxc5 is
actually very interesting in its own
right and it does invite positively
invites d4. But this has actually been
seen in quite a few over the board games
most notably there's actually a Vishy Anand
game against Matthew Sadler in
this line which happened in London 2014
it went like this Bishop takes check and
here in the VishyAnand game, Vishy Anand played e3 here so this is a legitimate
line and it ended up in a draw actually in
this Vishy Anand game.
So but anyway in this game we have
Bishop takes c5 Queen takes d5 and it's
as if Leela doesn't care about the
massive gambit compensation
which I find actually quite amusing for
me this triggers a memory of a game of
James Plaskett watching him play an over
the board game against another
grandmaster and he lost with
black and I remember him looking at all
his pieces being super aggressive and
it's as if Leela also doesn't care about
blacks pieces here being super
aggressive. There's an alternative
here Queen b6 but check is actually
quite annoying to play e3 now and this
is actually a small edge for white. So
anyway we have Queen e7 Qe4
is a very good solid move indeed it has
been seen before over the board
Nf6 and actually with Bishop e6 that
actually appears to be a very quick win
as in a stem game where a 2300 vs a 2000 player
happened a 2016 tournament which ended quite quickly
after these moves where black castled
Queenside and just seems to have a
terrible position here and actually
resigned here believe it or not. So this
this has been seen before. Chiron
plays Knight f6 which i think is more in
the spirit of things and look at all the
blacks pieces. They're quite aggressive
I just found this kind of amusing
Bishop d2 is interesting. White is in a better
position now to handle things like Nb4
which hits the c2 square
White can play something like rook c1
maybe sometimes Rd8 b3 and
now look at this Bishop f5. Look at all
of blacks pieces. They look really quite
dangerous -
you know this Bishop is active very very
active Knights. Okay so it does look very
active and dangerous to me all of these
possibilities. So what does Leela do?
Bishop e2 - it just looks a pawn up
but can black not do anything with all
this activity? Rac8 is played. If we
look at Nb4 here as
an alternative White can just castle
and after Bishop d3 a3 this
position is okay for white. This scenario
gets to be really solid for white and
the extra pawn in the center is actually
really handy for outpost on d4 and f4 so
this is a really important extra pawn
here - extra central pawn so activity
isn't everything if you have to
sacrifice like a central pawn rook. Rac8
h3 King f8 white castles. Black tries
to do something tactical now - Knight
e5 because there's pressure on this d2
Bishop trying to lure the knight away
from protecting d2 here. So what does Leela
play here which I find quite amusing? Let the trolling really begin now. Leela plays
Bishop c1 - this really is the best move
saying to black "Come and
get me" if Knight takes e5 is played here
then there's a bit of activity. This
should actually be about equal so forget
that. Bc1 Nc6
The Knight goes back. On Nd3 it turns out that g4 is actually very useful for White. For
example this position is very very nice
so that's that's gonna be in White's
favor and if we look at this again
instead of like Nd3 let's look at
well it's looking alternative here - instead of 
Be4 let us look at
something like Bishop g6 here. Ne5
again and actually white ends up with a
nice target on c5 here. So for example
this is a nice advantage for white. So yeah
the knight just goes back to c6 and
Leela seems in an underdeveloped
state. I mean this you wouldn't normally
go out of your way to have this kind of
position with all of black's pieces out
of the box here. But we have Rd1
just saying okay let's have a pair of
rooks off. "What you're gonna do to me now?"
Rd8 now just b3 and another
move trying to lure the defensive knight
away from d1. But it's adequately
responded to protecting the knight and
protecting d1 with the rook now as well.
So no problem.  Otherwise it's a
total disaster of course. If we look at
taking then there's rook takes d1 check
absolutely winning of course.
So Bishop b2 very logical Knight takes
Bishop takes and now Ba3 so
what has actually black got in terms of
compensation it seems to be rapidly
evaporating whatever compensation there
was. g4 Bishop g6 and now Nh4
trying to just get that light square
bishop and maybe take over this diagonal
even later. Be4 Bf3
now is played. Bishop takes Knight takes
we have Rd3 and now the bishop
just drops back to d2 here. h6 Rd1
okay going into a self pin but the King
can come to the rescue with things like
King F1 to e2 so it's only a temporary
issue King F1 and actually here in fact
Leela inflicts a pin tactically with Nd4
- a very nifty move to contest this d-file and further simplify. So black played
Knight takes d4 here. On Knight e5 then
Bishop c1 for example is very very nice
for example Bishop takes there's my f5
check and then like Nxg7 trying to
drag the King away from the rook but
then taking a big advantage to white
thanks very much two pawns up there
absolutely winning really. So Nd4
we have Knight takes d4 and now
exploiting the pin so Bishop c3 so
things are getting more simplified. Where
is black's compensation? And the funny
thing is Leela is now fully equipped
with endgame tablebase integration and knows
that this is a very favorable
endgame.  rook c5 Rc4 wanting the
trade of rooks. Here now we have Ke2
yeah otherwise the king could actually
be getting too aggressive and hitting
these pawns later so Ke2
Ra5 a4 b5 check King c6 and we
have that f4 h5 is played. on bxa4
here then Rxa4 is nasty.
The rook attacks a7 and if rook b5
well this have a look at this this is
just the winning King and pawn ending
and anything else is pretty hopeless
here. If Rb5 we just snap off a7
and f7 winning so we have king b6
and the rooks come off. Sorry in that
variation sorry so king c6 we have f4 h5
so Leela just plays g5 now f6 h4 f5 and
now creating a pawn majority e4 by
taking out that pawn a pawn majority now
has emerged a 3-2 Queenside pawn majority
So yeah things are getting easier it
seems B takes rook takes Rf5
that pawn is now protected yeah it's
more hassle just to take here and allow
this because then you'd have to come
back to a4 to protect h4 so that still be a
good advantage but this is easier. Rf5
Ke3 to just to protect the pawn. a5 and
now the Queen side is just dissolved
simplifying and and we're starting to
transition to a very clear endgame tablebase position soon I believe. You'll see from
the evidence of some of the weird moves
coming up very soon. The King goes to b5
here. It's quite far away from these
pawns you will note. Ra8 Re7 check and the
King comes and now to hunt down that g7
pawn to create actually three
connected passed pawns.
so one pawn goes then the other goes and
now we start to have hilarity. rook e7
now I checked this game out actually from
my iPhone walking daily in the park. I
was thinking ... did something go wrong
with the game score on this game? Surely
this is just nonsense - why the
move rook e7 here - I really thought there was some technical issue or something but it
turns out this is just an endgame tablebase win to take here is a pure endgame tablebase win.
The king is not Superman  - it's just too
far away from these pawns. These pawns
are just full steam ahead - three connected
passed pawns outweighs the rook so it's
quite hilarious in a way that this rook
is offered and actually is rejected so the
the opponent's also tablebasing this
perhaps and not liking that. If we look
concretely just to show why this is
absolutely winning yeah the King's just
too far away that the connected passed pawns just easily win smash
through here actually. So we have
actually check and then hilarity
continues with rook d7 and I'm really
thinking there's a technical issue here. rook c7 even
saying "look you can even step your King a
bit further taking my rook and I'm still
winning with the passed pawns!" Rd8
- one small step for the h pawn -  "Harry the
H pawn" - and now Ra7 - Leela is really
wanting to transition and simplify this
further but she does make a little bit
of progress soon with her pawns soon. g6
and now h6 like offering g6 here okay so
Black plays now Re3 check.
On rook takes g6 this is still an endgame tablebase win. After Rd7 for
example here this is just a winning King
and pawn ending after taking that
pawn is just winning. So we have check and now Leela doesn't mind
about the King
getting even further away from these
absolutely winning passed pawns so this
is a fine interesting entertaining
technique demonstrated here!  Check Rb7
and check yeah - rook b2 so
offering h6 that's not taken because
there's always g7 anyway
Things like g7 and it carries on yes a lot of
fun here check okay rook b1 yeah I
really thought there was something wrong
with the game score but apparently
this is this is really what happened
this is really what happened
so rook c1 yeah okay and rook b1
okay now finally queening deciding to
Queen okay check here wanting to give up
the Queen now check there yes yes it's
very very amusing blacks run out of any
pieces and Leela wants to go into
another proven  - as long as it's a proven
win for White then it doesn't matter if it
further simplifies so yeah we're still
in the winning position. A win as they
say "is a win is a win as a win!".  I don't
know if you've heard that one it's quite
apt for this game. "A win is a win is a
win..."
But eventually the
checkmate was delivered at move 121 so
Leela made this game as entertaining as
possible. In fact even involving a
classic stem game of Wesley So vs Varuzhan Akobian - in the
opening inviting a funny line with d4
with a quirky knight on a4
We didn't go into tha. Instead we went
into what seemed to be like a horrific
looking gambit but Leela as cool as a
cucumber is just retreating the bishop
to c1 at one point and saying to
black "what have you got ... what have you
got ... what have you got?" That was the
question in the opening and in the
endgame  "look take my rook take my rook... take my rook!". So I found it quite a
hilarious game from a number of angles. I
hope you found some amusement in it as
well. So is leela neural network the funniest chess engine troll going at the moment?What do you
