Hi there.
In this lecture, we see Anatoly Karpov against Geller Sacks.
This is a 1983, the non last tournament, round three.
We see Eiffel from comp off.
We have a Sicilian defense from Sax.
Note 3e6d4c text four note takes 349569 ac three and now D six.
So this is going into the and Ingram variation, but it does allow a potentially really strong Karras
attack named after Paul Karras.
But what can blank do here instead of d6a6 point has e five that forcing move would compromise black
structure.
So this position is very comfortable for whites with advantage.
However, 9c6 can be used to transpose into, for example, a Sicilian Resnikoff, which is an interesting
variation and respectable variation for black and play might continue.
Bishop E seven white taking on f6 C free, which helps reroute the knight sometimes.
So the knight later goes to C two, E free, generally speaking, and a four is a break later.
But DE six was played here and we have caras attack territory H six so this is a nice move to put the
brakes on.
G five if 90 6g5 we get a nice position for white, it's quite dangerous for black this ready made attack
that white has on the king side.
So this possession for example is in White's favor basically but so so D six is played and we have.
Of the G4.
Sorry.
After G4, let's get back the game six was puts the brakes on G5 from white.
So slightly different now.
Rook G one is played Bishop e seven Bishop e Fritz are not committing yet G 519 C six Queen E two.
Bishop d7h4 So black they're not Castle kingside.
We have 964.
Bishop takes the E4 e5 Bishop drops back to E free Bishop C sex Queen D free holding the E4 pawn Queen
A five White Castle is queenside and now black does something quite speculative.
Knight takes E for temporary p sac comp off actually obliges head knight takes e four.
So risk factor is that a two could be taken at some point.
But there's also this mobile sensor so D five so it's a speculative P sac.
And to avoid controversies, Karpov plays a very interesting move here, just going for a small, definite
advantage.
He plays Queen Bee free.
So this is kind of iconic cop off style.
He detects that this position just give back.
The piece is a way of cutting through all the complexities and controversies and potential for analysis,
mistakes and analysis holes.
So Queen Bee Free is an iconic kind of positional move, not minding smaller but more definite advantage
just to keep control of the position.
Just to show the complexity reduction here.
If Knight see free black actually can gain equality with D4, it seems so say g5d take C phrase.
So now A2 is really hanging, G takes H six and if black plays their cards right here, they should
play G tanks, same sex.
If they play Queen St's a two.
In fact, Queen takes three ends up being funny enough, better for white, the rookies attacking the
queen.
And here this is going to be better for white disposition.
But if black plays G takes H six hair, then the concept is very good for black.
The temporary p sac this position, let's say Queen E to hare well to protect the rook is needed C takes.
Yeah, it's going to be even Black's really done well here.
So 9c3 wouldn't be good night G phrase actually.
Okay.
For White's default, Bishop G two would be the key move.
So again, an element of giving a piece back to make sure that there is an advantage for white.
So here there's an advantage for white knight D two is another interesting move D four might be free
Queen takes a two queen F five.
So willingness to give back the piece again is expressed here of the G five.
So there's free moves to one of them.
Actually black with best player gets equality but calf move is very good queen bee free.
So we see a willingness immediately to give the piece back for this position.
And there's a sense of authority, a qualified of authority, a qualified control of the position.
In particular, Karpov is interested to gain control of the light squares here.
Bishop C4.
But there's a counterpart.
Bishop Right.
He wants domination control authority on the light squares.
So we have rook f eight addressing the concrete threat of bishop takes f seven if black castled g five
and if h5g6.
So that will be very painful on the light squares.
So a king h g takes F seven.
So okay, we have rook f eight and now there's a key move to really get authority on position.
The king's in the center, which helps matters significantly, the king being the center.
So what would you play here for 200 points?
How would you improve the position?
In fact, I'll give you two alternatives for 200 points.
Okay.
The simple alternative would be g five here.
So H takes, H takes.
This is dangerous for black.
Just Bishop D five plain vanilla G six does also get a kind of authority on on the light squares and
splits.
Blacks pull structure a bit white has significant advantage here even though technically black is a
pawn up.
These are kind of bad pawns.
White's pieces are just great here, but copper plays the alternative Rook D five.
This is a positional exchange sacrifice.
So this is fun.
Bishop takes D five, Bishop takes D five.
It's a qualified authority control on the possession, in my view, on the light squares.
So with B seven the target black plays rook D eight.
But here.
Och, it doesn't want to indulge.
Bishop takes B7 so the Queen takes his frightened.
We have Bishop See for now.
There's a strong frats here of Bishop B five check.
We have Bishop before so that interferes with White's control of B five if H five just to demonstrate
Bishop B five check, Queen D five would fratton not just taking the route, but also the queen after
queen drops back.
We've got an almighty pin on the D file that's going to just win material.
If a six we're just playing queen takes B seven here.
Bigger voyage so Bishop before is tried C three, b five.
So if Bishop E seven here we're back to Bishop B five.
Check with that almighty pin that's just crushing as example.
So B five, bishop E2, Bishop D six And now here, instead of taking on B five, we have Queen D five.
This is really interesting.
So Black's really pinned down here in center, King E seven and now getting rid of adult Square Defender
with Bishop C five.
So the Francis Queen size E five check we have Bishop takes Queen Tang's E five, check King D seven.
Queen C five, Queen C seven, Queen F five, check King E seven.
And now Queen takes E four.
Check King D seven, Queen at five, check King seven.
Rookie one one is building up forces against the king.
We have rook these things and our bishop c four check.
So this is a very accurate move to prevent rookie sex if Bishop takes B five.
Jack Black has rookie sex.
And actually this is about even yeah, black has resources here so important to rule out the rookie
sex resource.
So Bishop C for crack king D ain't if rookie sex we're just going to take on E sex and this possession
is crushing so King D ain't we have Bishop takes B5 a sex bishop a fall.
So let's count the pawns.
Six pawns for whites.
So four pawns for black.
Two pawns up for the exchange.
Not bad.
King's unsafe g sex.
What else if Rook have sex?
Queen 85 Check wrote sex Queen E five actually fraternize here.
Queen mating.
So this would be quite problematic in various ways.
And that site, I mean, it's a complex possession.
Let's say King Queen takes G7.
So anyway, G6 is played Queen S3, King C eight.
This makes things a lot worse.
Queen C five was needed.
So, for example, this possession, there's still a bit of a fight and it's unpleasant for black and
losing another pawn that white has an advantage building up still.
But King makes things a lot worse.
Can you see there's a tactical move now by Karpov for ten points.
What would you play with White?
So that authority that on the light squares is useful because it's actually restricting a king escape
square.
So what would you play here?
So it should give you an idea that there's mating combinations.
We have rookie seven.
Nice.
So, Rook D one check is played.
If Queen takes E seven, we have Queen eight.
Check, Queen A seven, check King The eight is Queen bee eight.
Checkmate.
And here if king Queen size E seven.
So yes, that's that's a winning line.
So rook d rook d one check was played
so this this is looking a rather desperate thing to do for King takes rd one queen takes E seven now
so trying to hold on to being next change up for the two pawns if Queen D six check instead Queen 6e71
can play queen a queen, a seven track.
And here the king can be brought up the board to a checkmate, a nice checkmate If rook the eight check
Bishop D seven check just simplifies.
So just getting things off and this end game should be one this queen and game we're two pawns up So
Queen takes E seven though was played trying to be the exchange up but what about King Safety Queen
eight check King C seven Queen seven King D six, Queen B six check.
And this is end of game.
Now in this position, Black resigned if King E five, Queen D four check King six Bishop be free is
check and mate.
So a very, very nice game from Karpov.
So we see an element of positional authority control lacking counterplay in a particular aspect.
Loot square control.
So a key moment, this lovely exchange sacrifice after Black's very interesting idea though very good
credit to get a sax for this very, very interesting idea.
It's just that Karpov was having none of it.
He wasn't having all those complications he had in mind, like square grip and turn it into basically
a positional pawn sacrifice for White's.
Right now it's one pawn down, but for that positional pawn sacrifice, the authority on the line squares
is significantly increasing now.
So this is concretely getting onto the Knight Squares with tempo and then the lovely exchange sacrifice.
For me, this is another iconic Karpov move, this rook DD five There are certain cop off moves which
really excite me, and it's nice to point out all of those particular games so that you can have a lot
of enthusiasm for Karpov games.
This is an iconic example.
Rook D5 five Positional exchange sacrifice after a possession or pawn sacrifice.
So think about the implications for control and reducing reducing counterplay.
Okay, So much.
