Hi there.
In this lecture, we see an amazing game, a classic game.
Very well celebrated.
It's between Edwin Adams and Canasta in 1920.
New Orleans.
Let's have a look at this game.
So, Adams with the way pieces plays E4, we have E five nines have three, D, six and now D, four,
E times D, four and now Queen.
Thanks d for this has an idea behind it after 96 to actually just pin the night so the queen can remain
in the center.
Why is volunteering now the Lions Queen Bishop And quite often when we do this we get darts.
Square pressure, more square pressure than usual.
There is a statistical benefit.
So night C free.
So statistically we could in theory, put more pressure now on dark squares because both these nights
could be involved, this bishop could be involved whilst black has one less piece that could operate
on dark squares.
That's what I mean statistically.
So it's an interesting situation here.
We have nights, have six white castles, Bishop E seven, and now Knight D five.
Bishop takes D5 so Black gives up that Bishop E takes and we have this shared file emerging.
We have black castling Bishop G five and now C six.
So okay, there are, there are options here.
H six could have been played here and Bishop D two is about equal.
Bishop F four this would be about equal of 97 and Bishop, Thanks Bishop H for here.
If H six was played, it's actually a little bit of an inaccuracy.
There's potentially black could play 1965 and we get a situation which is simplified, but it's still
about equal.
So anyway, C6 here was playing at C4 c c ten.
So now we have two shared files.
So the interesting situation, so the pawn structure is basically symmetric about one.
It has a more advanced pull on the default than black rookie ain't rook f one and now A5 rook E two.
And believe it or not, this next move Rooks here is actually a rather significant mistake.
At least in the world of engines.
This is a mistake move.
Y is able to build up quite menacingly on the E4 here.
Both sides kings.
They haven't got any air.
You know there's no lift, so to speak.
No one has made any lift.
Any air.
Like my moving pawns.
Give the king an escape.
So bear that in mind here it seems black should have played H six here.
This would help relieve any pressure build up if Bishop D to Queen D seven.
This position has Bishop f A and it should remain an equal position with this e4 having of no great
significance here.
It's nowhere.
No big deal if Bishop H for here.
Knight takes the five.
Queen takes this position.
ROOK Thanks, Queen.
Thanks, mate.
Thanks each for this is actually quite nice for white.
It's not as good as as earlier.
This is actually quite nice for white.
And if G5, though, let's look at this for a moment.
Just for the record, Queen D seven Rook 89, Stage five.
There's no immediate disaster here.
Queen B six though the pressure on the EFL could be used tactically in relation to D six.
So let's say Black kicks the Queen this position.
Mine should really go back to basics here to be annoying and just accept maybe a repetition draw if
that doesn't play.
Rook six Hare if King G seven Bishop takes D6.
This position was using that effort tactically, but it's still about even.
That is one of the options that Black had really this H six for g five.
Just for the record, if we go back here, by the way, if instead.
Of Queen Bee sings.
A friend, it turns out.
Yeah.
Bishop f6 would actually be potentially quite nice for black hair.
So anyway, that's a side story of the game, which maybe isn't told too much about this game, so I
thought I'd mention it.
So Russia is actually technically a big mistake because it allows this build up on the e-file, which
is difficult to parry.
In a way, Black's already technically lost.
Believe it or not, Queen D seven is played.
So the problem here is if H6 now there's Bishop takes F6 and what does black do?
Bishop takes black would lose the Queen with check, and it's grim to consider.
You know.
G Things have six looks absolutely grim.
If B six this position as the example if G takes hair queen G for check, queen for 94 the night, it's
going to go to a beautiful square potentially if 596 is even better here.
And once just winning material there that's crushing that 96.
So anyway, Queen D seven was tried and there is still an issue with this effort with double rooks why
actually plays Bishop takes off sex and you might think, well, what's the big deal?
There is a big deal made here of this battery on the e-file.
Can you see what it is for 200 points?
One is why it play here.
Okay.
One doesn't want to play rock tanks because then rock tanks and this is no big deal.
Even no one plays a spectacular move here.
Queen for trying to lure the queen away from ain't.
Wonderful stuff.
We have Queen Bee five.
If Rook takes E to the night, protect C one so White could take the queen and say here with the knight
just winning advantage.
So Queen B five is tried.
So just to put this on, the board of the Queen might lose his control of weakness of the last move.
Basically, rook takes he ain't rook to his mate.
So Queen Bee five.
And now things get really spectacular here.
If White plays a bad move here, White White's lack of air around the king could be exploited if White
plays a fool.
Can you see what black would do here?
For the record.
So the default weaknesses of the back row, you know, can be, you know, for both players in certain
variations of this game, Black could play queen thanks to her after rook takes rook c one shank rookie
one and then a back row mate happens.
So why it has to be careful.
So this next move is super clever.
It's actually for 200 points.
What would you play?
So that is a key threat to identify.
There's actually Queen C for basically shielding the rook, hitting the queen and still trying to lure
the queen away from E8.
We have queenly seven.
So just to look at things here, Rook st C for rook types, E is crashing through for a main queen tank
C4.
This is crashing through for a main queen A since we just take on a gang and then mating.
So
it's a very interesting situation right now continues with another outrageous looking move.
Can you see what that is?
Okay, it's Queen C seven.
So saying, look, if the rook moves or the queen moves, we're taking on E eight.
We have Queen B five.
So, yes, just to put this on the board, Queen 67, we're crashing through Rook, take C seven.
We're crashing through.
Okay, so Queen B five is played.
So here.
We've got we've kind of locked down the C file for a moment with Quinn on C seven.
So here there's a very interesting move played.
So can you guess what that is?
Okay.
It's actually a four.
Yes, it will be a mistake to play Queen Saxby seven because what we're playing.
Yeah.
Queen Sexy two again, this is this is a nasty thing.
If Queen takes eight, Queen takes one.
And here Rook takes a piece up for black.
So that wouldn't be too clever.
Queen takes up seven If we look at this.
If Rogue takes E to Rob, see one check.
And this is just mating.
So both sides have got to be aware of this kind of default downside that they've got.
So a fallout does do some good thing here.
It does a very good thing, kind of a magical thing.
Here we have queen size and E4.
And as a key point made now.
But before we get into queenside, say four.
If Queen takes E2, her rook takes E2.
And what does Black do?
If Rook takes her to Queen St St and then mating.
So yes, Queen thanks.
A4 trying to hold on to E8.
But now another amazing move.
Is played.
Okay.
It's actually rookie form.
And this is very, very clever.
We have Queen Bee five.
If Queen takes E4 here, rotates E4, and again, black has a bad situation.
If Rook takes E4, Queen St and that is actually a mating point.
So Queen B five.
And now the Queen is not looking at E two as a forcing move.
Its like ruled out a key forcing move by having the rook on E4 instead.
So guess what is a powerful move now?
And the rooks also controlling of course the A4 square as well.
So this makes the next move.
It's like taking away escape squares of the opponent's queen, in effect, in effect.
That's like in the Art of Checkmate.
But we're kind of doing this to the Queen.
So White's play here has a crushing blow for 200 points.
Okay.
It's actually Queen Bee seven hits in Queen.
When does the queen want to go?
The queen can't go to a four now.
And the Queen has to hold on to it.
Eight So this is end of game.
If Queen a fall we're just going to take because we've got our work protected here on E one.
If Rook B ain't Queen Sykes B five.
And what does do takes those rook takes e8.
So it's an absolutely astonishing game.
But actually there's a debate.
Is it analysis or an actual game?
It's more likely to have been an analysis, but it's still super instructive engine's figure.
It's not really accurate sequence and it shows the basically the default downsides of chess.
When we don't make air for the king, we can, you know, it can lead to problems.
And also when we do make air for the king, it's like unnecessary weaknesses that can also lead to problems.
So chess is a hard game.
KING Safety is a dangerous subject.
It's a difficult subject to master the balance between making out or not making air.
It really depends on the position whether we want to be attacking players or not.
We need to play accurately and that's why it's good to have a kind of interest in details here for how
the advantage emerged here.
What chemo's black had missed out.
So one gets this kind of overwhelming pressure situation on this e-file with, in effect, pressure
on air, which is difficult to address after this combination queen fall.
So for me, this is an absolutely iconic, beautiful demonstration of default downsides in chess.
How, you know, even, you know, an opening sequence, which seems as though black didn't do too much
wrong on this occasion, but it's actually a lost position after a particular inaccuracy in this game.
So the inaccuracy is, okay, you know, if you look at it through engines, already 90 plus frames
more than plus two after Roxane.
So yeah, it just shows these default downsides are things we need to pick out downsides in general
for accuracy of playing positions.
So we, we want to get our ability to have final finishing combinations, but a smooth ride, getting
there.
We don't want to necessarily play like the romantic era with unsound gambits.
We want to get into places in a sound manner so we can repeat and have consistently good results, repeat
our attacking efforts and have a consistent level of results we're playing accurately.
So yeah, this is a very accurately played game, especially from here to exploit.
Roxy.
I so hope you enjoyed that and so much.
