Hi there.
In this lecture, we see an amazing game between Robert Byrne against Bobby Fischer.
So this is in 1963, the US Championship Round three we see D fall from Robert Bunn nine 10:06 p.m.
Fischer c4 g6g free C6 Bishop G2, d5 C tanks C tanks.
So we have a symmetrical pawn structure right now.
Knight C free, Bishop g7e Free Fischer consoles nine G2.
So the Knights are slightly different.
This one's placed on A2 rather than F3 if we want to mirror the pieces as well.
Black hasn't committed to E6 though.
Knight C six consoles are now b6b frame bishop A6 Bishop A3 so White's imitating black.
They're on this queenside which looks very symmetrical indeed.
We c Rookie ain't Queen D two So there's a question here.
Surely E5 is out of the question to have a weakened D5 pawn?
Well really depends on the position.
And here even engines now love Fischer's next move.
Fischer actually does play E5, giving himself the isolated Queen's pawn IQ p for short.
So after D takes E5 because what else could this have been avoided?
Well, possibly.
Let's say Rook fc one Black could have a good game.
He tanks d4 this position of the 18th e fal rook since my f4 black has that hook on the E4 square with
that rook ready and waiting to support the hook.
And we get a situation here which, for example, this could liven up.
Bishop takes A1 Roberts A1 95.
Black is going to get a small edge here.
That's a dynamic thing for White to do that to take on E4.
But otherwise, what about the pressure on D4?
Yeah, that's so yeah, this is a difficult position for White to have to give up the exchange.
So, yes, that's one impact.
Potentially that hook on E4 basically could be made use of pretty soon with the rook on E8.
If this isolated queen pawn structure was not accepted, if we go back here and consider actually.
Also.
Bishop the fall.
It is interesting as well if the tanks e free.
This position with it.
I have to check.
Bishop takes a one.
Is very, very dangerous after rookie one check.
Yeah.
There are various possibilities for black.
So even if Black wasn't given the IQ structure.
But anyway, black was D tanks e5 and we have 96 e5 and now we have the case of the wrong Rook.
There's two rooks which could have gone to D one.
This one has a kind of weakness of the last move.
F2 is a bit weaker and this becomes.
A kind of priority for black to make use of F2.
Pretty soon if rook add one.
This is more testing say Quincy eight 1965 1985 Bishop 65 Rook the eight.
And the thing is here that say four black has a resource here.
Can you see what that is?
Which could lead black to a small edge?
Okay.
Black could try and get onto this.
We can diagonal by taking out the thing ghetto bishop.
And quite often, if you weaken the opponent's king, it's like your pieces get promoted.
This bishop is now kind of more dangerous than usual.
It's more than free because it's getting involved in mating combinations, potentially.
If Queen D two, Queen C sex white would have to give up material.
Actually how white defend on diagonal.
And if this is the case here, then Black is doing quite well in this position with a small edge.
So that was interesting.
It's much more interesting for White to have done Rook 81 rather than Rook 51.
So after this move we see Knight D free and this is really quite an annoying night indeed.
We see Queen C two.
So as if the friend, you know, Rook 63 and Grandmasters 40 Fischer might have been in trouble here.
What is going on here?
Well, the thing is, he plays now a brilliant move.
If instead of the Queen C2 though, just have a look at 94, then there's no E4 using that hook and
this would be cementing the knight on D3.
So this possession, for example, would be quite nice.
Black has Bishop C free and this is very pleasant for black.
That isn't such a weakness having the knight on D3.
It's just it's a nice position.
So Queen C2 though.
So this next move by Fisher is absolutely brilliant and it kind of recognizes basically when we have
a dynamic pawn structure like an ice queen, Queen's pawn with the extended hanging pawns, sometimes
these guys are getting in the way for attacking potential against the king.
So just bear that in mind.
But also, of course, we need to bear in mind if we weaken the opponent's king, we're giving our pieces,
you know, potentially a promotion because they might be more valuable for hunting the king.
So here the bishop is only in a support role.
So I'm about to show you the Fisher move now.
Knight takes F2.
Well done if you found this 100 points.
So King tanks.
And the point is Knight G4 check King Ju on the king can't go to F3.
It's out of the question.
Rook takes every check is possible.
Doesn't matter about the knight on G4.
If King takes G4, there's h five check and black gets mated soon like this.
Checkmate.
And if King f4 again black gets mated soon like this.
So this would be checkmate.
So the king has to go back.
Knight takes E frame Queen D and here the beautiful point about this pawn, it's kind of a constraints,
potentially Fish and Nell plays a very, very strong move.
So which way to take the bishop or the rook for 100 points?
Would you take the bishop or would you take the rook?
The right thing to do here is actually to take the bishop because it's weakening.
The opponent's king.
So weakening the opponent's king, especially the light squares.
That was the guardian bishop of the Lion Square.
So it actually promotes this guy because this guy can work on the light squares now without the counterpart.
If Fisher had taken on d one route.
Thanks d one.
This is nothing to really write home about here.
Bishop takes the five is an equal position.
There was, however, an alternate to 1962, which was also very strong here, showing the actually.
Hold on the four.
It offers the special blank on ice.
And the thing is.
If the night moves here.
Then there's no it takes G2 and rotates E to, as example, saying the knight moves, Knight takes G2
and then rotates EA two.
And given that the case of Bishop takes eight.
We do get the Queen menacingly looking at G2 teammates Knight for protecting G2.
This position is very strong for black of the C2.
Bishop takes A1, Rogue takes A1, Knight D one and nothing else but French thing.
The e one square if Queen D2 trying to hold e one queen F3 and it's quite vicious.
Queen f1 mate France and trade queen takes G4 he won't just crumbles her basically.
This is a crushing position to be in.
So.
Okay.
Yeah.
There's very, very interesting possibilities here, including the.
That was also very strong.
But 1962 is absolutely amazing what we're about to see.
King takes G2.
Because if you don't testify, we're just going to take on Ito, for example.
So King takes two.
But now what's the key move here?
So the pieces have gone up in value because the king's weaker.
We can assume that it's not just that piece, but potentially other pieces could be involved in king
hunting as a sport and come together as a team here.
Okay, so here black plays now default fisheries, letting the pawn go to get this diagonal access.
That's the funny thing with dynamic pawn structures, especially the ice Queen pawn.
Sometimes it's just a restraint.
Sometimes you just want to take it to the next level, make it disappear as a sort of line clearance
tactic.
So yes, and the same with quite often, if it was hanging pawns, it's often a pawn sack just to let
a pawn go just often liberates the pieces, which gives us good potential for attacking combinations.
So here 964 is played.
It's a difficult position.
If the night moves, we're playing rock tanks, aid to Czech bishops, quite useful where it is at the
moment for such tactics.
So Knight takes D4 now Bishop b7 Shank.
And this looks very scary after killing of one.
Very, very scary.
If Qing ji won.
Black has a tactical sequence here to win material at the very least.
Can you see what that is?
Okay.
There's Bishop takes the fall check.
And here, what does black play?
It's actually a funny move.
Check who checks Rookie one.
Check.
So the rook takes protecting the queen.
And otherwise, we just end up.
We take the queen here to win the A1 rook and win the exchange up.
So the king went to F1.
And now there's two really great moves with the same kind of goal achieved.
So what do you think one of the two moves are for 500 points?
What would you play here?
The value of all the pieces has gone up all of a sudden because the king is weaker, because the king
is weaker, the pieces of more things to do, more fun is available to them.
And we see Queen D seven.
Queen Kate would have done the job as well.
The huge frappe basically is Queen H three and actually White resigned her move 21.
The grandmasters were completely shocked by this game.
They thought fish would have been slightly worse.
We've lost that in Queen's Pawn.
So yes, a total of the unexpected, to say the least.
So let's look at various options here.
If DB five, let's say queen and free check.
And there's a key move here which is crushing.
Funny enough, can you see what that is for?
Ten points?
What's the crushing blow?
Okay, Bishop only syncs with tempo against the Queen.
So yeah, the value of all pieces, including the bishop, has gone up, and this one has gone up because
we're hunting the king.
Queen C two Bishop E Forecheck.
And then here we don't even have to take the queen Queen due to a checkmate.
So that's just one option which just miserably fails.
Queen F2, Queen H forecheck.
And here, guess what?
We can play in this position.
Which is cute.
20 points.
What would you play?
Beautiful variation.
Yeah.
The value of all the pieces has gone up because the king is so weak.
ROOKIE one check.
So the queen can't leave G2.
Queen takes queen.
G2 is minus.
And given that's the case, if Rook takes E1, we actually can play.
Bishop takes the E4.
Ouch.
Rookie three We're going to get that queen away from G2 there.
If King G g1, Queen H three So we're threatening immediately things like Bishop takes the fall check
for Queen G2 one just won't do 95 Here again.
Bishop h6 and Bishop e Fray.
It just fells D two We have Queen H free check.
And here if King g1 Queen G2 is mate if King E1.
Here.
This position is crushing.
Queen St's H two now carries with it the price of Queen g1 mains.
If Bishop e seven That's desperate.
Queen H one shank.
So the bishop is just temporarily unpin the Knights Barts King f2 queen.
A free check.
King one and just taking here.
It's just crushing.
There's a bishop.
Take C3, for example.
You know, this is just hopeless or asexual, just piling up the pressure is a crushing position.
Rook E1, Queen H3, Czech Bishop 64 Choke Yeah.
So absolutely crushing knight See two Czech queen.
Thanks.
So frightening.
Queen G one Let's say Queen D three.
Bishop H six here is nice to frighten Queen G1 Renew Queen G1 as a mate Fat free bishop tanks and free
Queen sex are free.
There's a choice that will make combo here.
Can you sit up for ten points?
Queen.
Gee, one check.
And now can you see?
Check who checks.
Check the killer.
Common squares.
Yeah.
Rotates e to check King takes E to Queen for his checkmate.
So yes, it seems in all variations, one is doomed here with the weakened king.
So the game ending on Queen D seven.
As I say, Queen C, I would do the same thing as well.
Maybe some variations slightly different, but Queen D seven was preferred from fresher is more central.
So yes, a wonderful demonstration in my view of the dynamic potential of the isolated Queen's pawn.
We see in some variations the hooks like E4 being used if white and played differently.
And in the main line of the game that week in King made all the black pieces kind of more lively, more
fun.
They had things to do, especially the special.
But other pieces also playing a big role as part of the team.
Teamwork came together after the king was weakened, which is a common phenomena to look out for.
You're giving your pieces a lot to do when there's a more weakened king.
But the queen's pawn, the main theme.
Yeah, just a dynamic structure can be taken to its limits just by sacrificing parts of that structure
just to literally make way for the pieces.
Pawns are the fundamental constraint.
On the pieces, basically.
So that's something to bear in mind.
They are a constraining factor by getting rid of the pawn.
This bishop had that fantastic diagonal to celebrate.
OC and Steen Simple Chess indicates that.
And among other things.
That's a great little book to think about.
Stained simple chess to download.
But yeah, that's one of the amazing sayings from from Steen.
So.
Och, I hope you enjoyed this game so much.
