Hi all, I have an absolutely fascinating game from the Leela Test Server.
This is the Leela Test Server ID
10171. So it's a different...
ID format, much bigger number -- so ten one seven one.
And this game was submitted by...
Enrico Caruso.
And...
It does seem to have a
theoretical novelty. I've been checking against online
opening databases like http://www.chessgames.com/, let's have a look.
It's within the classic, most researched opening ever in chess history, the Ruy Lope, so
it's interesting to find a novelty in the Ruy Lopez. e4 from Gull 3
So, Gull 3 against Leela. e5, Nf3, Nc6, pretty standard stuff
so far. The most trodden opening in the history of chess, the classic Ruy Lopez.
a6, Ba4, we have Nf6
White castles, and we have the Ruy Lopez: Open Variation
Known as, sometimes, the Tarrasch Defense. Nxe4 within the Ruy Lopez: Open Variation
Just taking here, on e4.
d4, this is well known territory so far
Now, this is slightly unusual to take on on d4, because it seems as though this is
potentially bad because of the e5 -- I think it persuades a lot players not to play this line, instead much preferred is b5.
So for example, here, d5, and white
closes up that E file and this must give some comfort to black, black has to deal with the d5 pawn, but this is very well known
and I think used in World Championship matches between say
Karpov and Korchnoi, I believe. This is definitely
an opening used at world championship level, this particular...
variation.
White is thought to have a small edge but it's no big deal. So that's the safe line known. Mow
we're veering into what either is beginner moves or absolute genius here.
Not quite yet. It's after this move, again, here, d5 has been seen before, but I'm not sure in this position
It's meant to be that good. Bd6 aims for basically a draw after
[Nxc6], bang. Bishop takes, and [Kh1] because if the King takes it's a draw by perpetual check.
In this line with a petrol check
But the thing is... white, here, can actually sidestep that and
get a small edge
with Rxe4+ believe it or not and then forcing
the queen off
with Qd8+
So this is a clever tactical idea and it ends up white has a small edge here. You can see white's got the bishop pair.
And also,
When it has three [pawns]... white has an extra piece basically, so two pieces against the rook. White's thought to be slightly better.
Now as I say this, this is the Ruy Lopez, this is heavily trodden territory here.
So, this position
D5 is is known but it's not supposed to be that great.
This move, now.
Which is played...
is f5.
And
There are two games I found
At http://www.chessgames.com/ with with this continuation. Miller against
Giblin, 2011, which was a win for white and
Rinder against Bloch-Nakkerud at 1939, which is a win for white. So they had Bishop...
After Re1... f5. Nxd4
They had, basically, Bc5 was played by Giblin
In 2011, just looking at my monitor there, Be7 was played in 1939.
So quite a long way apart, only two games at http://www.chessgames.com/
So is this position... does it have something?
Is this some sort of weird new discovery?
There is a weakness of the last move on my f3 taking d4 that the 84 square has been neglected
and it's that which actually leave that even though the King's
Tightly in the center here and it seems ridiculous to go on to the attack
It's a rule breaking movie shouldn't really be going on to take the king still in the center, but we have Queen h4
Now
That doesn't give white much time to try and exploit the Kings sense because of that Queen have to check
possibility and taking on d4
For example, so the Queen's kicked back so we can sum squares though, and the Queen goes to f6
Which makes it annoying again to play f3 because there's Queen takes d4 check hair and white could end up losing the exchange
If not careful with a big advantage to black
but here
Now
this position is still I think most people would regard it as
Ridiculous and not worth exploration because white plays Bishop takes c6 Shirley
Which takes the pressure off default this is ridiculous, right?
And I'm just wondering if if it's because it's so ridiculous this this whole line has been totally obscured
And there's even more rule breaking as well to make this even more ridiculous now
Believe it or not
You might think
Details might might be useful to try maybe
Castle queenside or something, but no we have beat X which represents?
Starting to represent a full-piece sacrifice because F fries can be played with the King on the center
What does play every but it does weaken that diagonally and
Notes that you know, the g4 had weakened some light squares. We're weakening a bit the dark squares a bit
so we see Bishop c5 and actually here is is interesting, theoretically
White supports the night with c3 it seems as though is already very you can check
The the detail page again in the pink comment. It seems Bishop III can run into F. For example
G takes likely six this is very very scary for black with the King in the center still. So look at this tactic
97 check
It turns out here that black might actually be okay
My XUV and even position you can see that the pawns are shattered the bishop might be quite handy
It's not that bad. Even though black is two points down there seems to be a lot of compensation making it dynamically an equal position
so it seems this bishop if he does run into F for another ideas say Bishop f2
This is the full piece set concepts now d5
Which it most certainly obscures the whole fingers who would want to give up a piece hair like this
What is the compensation in fact?
It does seem to be compensation here
For example c3 Bishop d6. What is actually white doing?
Like Leela has got the potential for thr
CH o RN and she's also got the two bishops trained against the king in a way
I'll give you an example D takes e4 makes it actually difficult for want to take on e4 without getting smashed
Here, for example, Queen takes e4 FG and why it actually gets smashed because now there's a fret of queen f1 Czech mating
I just put that on the board to show you that's at standard mating pattern. So say what tries to parry this mating pattern
My play Knight d2
That's right. So we're taking on e4 F G Bishop Bishop a trait. So fretting Queen f1, so same nightly to
This position here after check is very dangerous for white after work have sex with the idea of cage sex
So for example here taking and uncheck wins the White Queen with an advantage to black
so basically
This I
Would say increases the potential obscurity of this whole thing
In fact that maybe it was also for Bishop. He free was a simple and strong
So let's go with C free which doesn't make use of the bishop since the piece is still on the first row
Let's assume this is a reasonable move
This is a full piece AK
Queen g6 is
This a new concept, I don't know what it is. There isn't any decent games in chess place live book with this
so it makes it kind of exciting it's like
It is like a scientific discovery or something
It's in isn't the most trodden opening of all time the Royal appears in the open variation and Terrace reaction
Well, what is this
You might ask
Why plays b4 here I?
Mean we can transpose we can try the to take the piece here
Say b4 Bishop e7, it seems white might have Queen a4 which which seems to pin down against d5
Basically that you might be wondering why Queen eight for this is mine
And I says here it seems as though in theory white should have a big advantage in theory
But I'm only I'm only checking these with standards
Engines there might be a better way of playing this but it seems as though in theory. What is a big advantage there?
So Queen a four might be a critical test of the whole thing because one justification here that I could imagine
Is is basically if p5 is allowed it's an aggressive pawn chain
Which means that once black castles there's the F valve especially coming to H free here on light squares
Basically, it's like that this aggressive pawn chain is like an open invitation to get the party game with all the pieces
Attacking the King. It's very aggressively set up for the pieces to be able to have a party on the Kings side
essentially and I've seen this concept before I remember on TV those this game onto a rapid game between
Michael Adams playing white no usual plan and Nigel with the French defense acts like a piece to get a very aggressive pawn chain
We've spearheaded with E for and later. He got a really vicious attack. I managed to win there in brilliant style
So sometimes the aggressive pawn chain is like a gnome open invitation
two attacking
potential attacking pieces later
So is it worth for an entire piece sacrifice to get this aggressive pawn chain?
So we'll go back to the game now
So b4 so after Queen g6 b4 was played first before taking on e4 Bishop e7
and
Now of course unpinning the night, so there's no time for Queen a4. So F takes e4 and we get this situation where
What what?
Do we believe this is?
Don't believe that this is worth a piece maybe white should try and restrain black against d5 here I
Mean a lot of things need investigating here
White plays Knight d2 and now black gets in this d5, which is what I'm saying. This is this aggressive pawn chain
I let's say once black castles. There's light squares to tap into because of the cheeky Queen
h4 earlier
Which as I say the whole thing would have been plunged into obscurity because it's as though black was playing like a total beginner
But in fact palms don't go backward. So the earlier weakness creation
Seems to marry well with the piece sacrifice here to get a spearheaded
Aggressive pawn chain here, which the light square bishop can at least enjoy
so we see her Knights who to be free and
Black doesn't even cut
The road so g3 is also a bit vulnerable
A pool has been lost away from White's King shell to take that piece earlier
And this is a pawn chain is is already feeling some pressure, but you're meant for now black castles for anything rook takes f4
Queen d2 is played holding the bishop
It seems as though Bishop tanks is is something to investigate mister mate shrieking. H1
It seems as though for my analysis
This might be already a very dangerous position for white and black
Might be able to at least win the Queen it seems as if if Queen e1 is is is needed
I mean, for example, there are probably things like III and Queen e4 check so Queen e1 turns up on the books
Just giving up the queen here as the move
Which gives black at least an equal position after e3 now?
Even musician so this is this is really fascinating stuff
About Queen d2 is played rook have seven. So trying to hold the fort not allow any infiltration
I guess the Queen need to move now
It's not really possible to take on c7 because of Bishop g5 here hitting the Queen and hitting
The bishop the bishop retreats then we're snapping that off and the pin palm. We're winning a piece
So we see here King h1. So now okay
This might be on if White's really seems to I doubt it now because there's other concerns Bishop g4
Potentially the Knights holding every at the moment though. We see Knight a5
In fact taking here might be better just to double the rooks by the way
So what didn't indulge that extra material gain white played Knight a5?
Going for c6 which would weaken a5 you can see like coming to if I would fought Queen and rook black reacts. That was c5
So now we have Knight
d c6 so frightening 95 among other things
on B takes
Bishop takes this position is
Interesting, of course
But some it seems as though just I'm just giving an example
Continuation where black can take on d4 basically to get this check in and should actually be okay in these lines
with III because then if
Yeah, this looks okay. If Queen takes e4 them by wait
Then there's Bishop takes d5, you'll see all these variations in that pins comment the pin PGN if you want to check them out
So basically white didn't take on c5 we have Knight dc-6 and
Now we have Bishop d6 sort of addressing the e5 concern
And it's too sly gets to take on d5 here because the bishop takes at have four and then Bishop a free checkmating
So it's not it's unpalatable to take that we have Bishop takes d6
The check isn't news to hear no see takes
Now we have beat st. C-5
Now, well them both this deep one is holding against 95 black Ashley likes that doesn't want to do anything with that poor mother moment
and just plays H for
As I say these pieces not really helping the King this spearheading pawn structure
Is letting the PC the attacking piece is enjoy
Attacking basically with a kind of free hand here for the moment
We have
So we'd have an H for if D takes e5
then that weakens the e5 square like you fight for king queen and rock and
This position is just a big advantage for why there's no no attack. No nothing there. So we have h4
being played Queen takes d5 and they'll rook e8 and
This is already really dangerous. By the way. Now Bishop f3 is already really dangerous as well this position with
Th7 for example like this
But we're h5. Black has a big edge here
The attack is very dangerous in this position because of hg possibilities and Queen each one Rock f6 to g6
Which is reflective of the main game continuation now
But Lee that wants to support Eve for here at first after takes now we see Queen h5
So there's ideas Bishop f4 and HG and also bringing a rook in
So we have here rookie free check
Kings you want H tanks? G3. Yeah, the the the bishop track is actually interfering with the rook helping to defend here
So now if hg, then Queen h1 winning the rookies is a big advantage for black
So we have Queen takes chief rate and now rook left. Yeah rook g6 is now threatened
So we had likely for Brooke g6, yes and blacks now
Winning that Queen and this is a very good position as you might you might expect
Taking on c5 now
this is
diabolical visits actually fucking the rook and Knight well
Basically there's yeah, it's
it is a diabolical position now and blacks just
Queen in estrus is trivially winning now with this past April tank attack carries on a bit
Until here, so obviously just queening. Yeah
It's convincing
so I don't know if this game is really representative of something that needs to be checked out a
theoretical opening a novelty as I say I've done my you know, brief brief checking with chess games comment and chess based live book and
These lines were taking on d4 and f5 is just basically what you know
lower rated players would play not with any amazing idea follow-up
But it seems that the same moves which provoked weaknesses like g3
Can actually be the start of a spectacular night sacrifice intuitive night sacrifice
by the evidence of this game, which appears to be
Very good compensation potentially what I'm unsure of myself other lines above Queen I for trying to stop this
aggressive palm formation
actually happening because once that does happen you
Know intuitively. It's like an open
It's like makes it
Invitation friendly friendly for the the party of attacking pieces just to build up against the White King as we saw here
So, I don't know. This is really fascinating. Let me know if you really think this is an interesting opening novelty this within the open
Variation of the Royal pairs the Tarrasch in brackets the terrace defenses that sometimes referred to so royally pairs open
novelty or
mandus
