Hi there.
In this lecture, we see an absolutely iconic game, one of my favorite games of Tigran Petrosian.
So this is against Boris Spassky in their 1966 World Championship match, Round ten.
So take around Petrosian kicked off with nice and free.
We have nine, we have six, G three, G six.
So both sides V in Kettering, the bishops, the King's bishops.
Now both sides.
Castle, We have 96 knights C free.
So this is a Kings engine defense for an ket operation.
We have a six.
DD 595.
So this hits the c four pawn 92 and now C five.
This is a standard way of trying to generate some counterplay with the black pieces.
Queen C two We have E five.
So now we have B free and on Knight G four.
So Spassky is wanting to launch an attack on this side of the board with F five.
We have E four, F five and now E takes F five, G takes F five.
If Bishop takes a five.
We get the E four square to play with, which can be very useful after Knight D four.
That's a very nice kind of blockade which also hems in the G seven bishop.
So this is positionally quite pleasant for Y.
As example, this situation, even if we release the blockade, we can renew it with 94 later.
And we're looking at the a five knight here with this bishop.
If it goes back.
Yeah.
Once it's got a very comfortable position here.
So basically g takes tries to keep e control.
We have 90 1b5 and now F three.
It looks as though White's pieces are a little bit passive on the first two rows here.
So this move looks at the rock.
We have Bishop B two, E takes our free bishop takes our free and our bishop takes B two.
If we look around the squares, around the king, we're getting a vacuum here around the black king
queen, thanks be to potential weaknesses which could be exploited later.
95 the bishop goes to e to hear this safeguard C for we have that F for very aggressive, playful and
Spassky even though he's weakened this king.
So in effect, it is a bit like weakness, provocation in that an incentive has been given for black
to create weaknesses around their KING So this is a kind of.
You could say a position or strategy to encourage your opponent to go on the attack and to kind of burn
the bridges, you know, make committal decisions like creating weaknesses We have now, G takes F four,
it seems in this position, takes F or might have actually been technically more accurate.
This position, for example, is going to be better for white.
This situation is actually better for white.
And we can take this a bit further.
We can see the vacuum of weaknesses with nine of six on the cards or the queen being able to hit a five
and go to G three later.
This situation is rather pleasant and there's even tactics like 965 in this example variation hitting
the queen.
So there are danger points associated with Rook takes F4, but G takes F four was played.
This leads to a very interesting game.
H free and now a really interesting move.
So black's guardian of the light squares is this Bishop?
Guess what Abraham Petrosian plays here, which is really interesting for 100 points to try and expose
further and connect to the existing weaknesses which have indirectly kind of been provoked by saying,
Come and get my king, come and get my king.
So what do you think the move is here that won't place?
Yeah.
93.
Just offering an exchange.
We have Bishop takes everyone.
And this is actually a mistake.
It gives a very dangerous position now for white winning the exchange here.
If Rook takes F4 instead, this situation with Queen G five check.
Bishop takes G for light and takes G for $0.09.
G for Bishop G for Queen G for check.
This situation should actually end up being about equal with best play for both sides.
There's yeah, there's Waynes ways it means for this to maintain equality.
This situation if rook takes a two check here the king gets active.
There's enough compensation for both sides to work with to draw.
And if rook g check again, you know this is going to be draw ish.
So that would have been an interesting move to play.
Rook takes our four here leveraging the idea of Queen G five check but with Bishop takes F one.
This vacuum of weaknesses around the King is also potentially on the line squares as well.
So we've got like square weaknesses as well as dark square weaknesses and they can help to really create
dangers around the black king.
We have 96 and our Bishop G four and already we have a bishop coming to e six.
It seems exceptionally dangerous, but isn't there a technical issue and then it takes her four.
Doesn't that stop any use of E six Guess what Tig controls in place air, which is absolutely brilliant
for 100 points.
Yes.
It's just a technicality.
It takes her four.
It can be erased off the board with Rook, takes her four.
So double exchange sex so far from white.
And the rewards are rich, though.
So already black has to go back with the rook and look at this vacuum of weaknesses.
Now around the King, the knights are ready to pounce.
94 is played.
We have created four.
If B takes C4, we can play 95 with menacing ideas and direct mate France on G seven here.
So this is for example, mate.
And yeah, it's just so dangerous if queen if I Queen F six.
And the thing is here we can play Knight G five and six, F seven and Bishop takes F seven check and
H six check.
Everything is crumbling.
So Queen H four is tried, but now it has the point to hit the Knights.
We have Knight 66, Queen G five.
Check and hear King H one is played.
We have Rook 8a7 if queen takes a fray.
The thing is, Bishop takes F seven check king for we have Queen H eight, check King seven and now
Knight a five check.
And this is kind of vicious.
Our Queen's attacked her, but we're attacking the opponents queen.
And here we can play Bishop E six check.
And the thing is, we're grabbing a check to get our queen out of danger, and then we're going to take
the opponent's queen next.
So Rook eight, a seven, was tried, but now an absolutely beautiful finish.
Can you spot the finishing combination for 200 points?
Really beautiful stuff.
It starts with.
You might want to pause the video.
It starts with Bishop, takes off some check.
And here is one of the most magnificent Tiger Stadium tactical moves.
In my view, one of my favorites.
One of my absolute favorites.
Very iconic game.
So Tigran Petrosian, you know, they say he's like Tao in terms of tactical ability.
Just usually, you know, he reserves his tactics for defense and not losing.
But you know, we can see the magnificent tactical abilities of Tigran Petrosian with this next move.
So check all checks, even the most outrageous ones.
And hopefully you'll see that that vacuum of weaknesses is brutally exploited here.
Yeah.
Queen h h what a magnificent move.
And it ends the game.
If taking note takes F seven check, Why, It's just a whole piece up and also a pawn up.
So this is absolutely a winning position.
So, yeah, a beautiful game.
It really is a striking game for weakness, provocations, you know, trying to encourage weaknesses
from the opponent, giving them what seems to be a legitimate agenda to get to your king.
But the fact is that they're creating weaknesses in the process and there were expertly exploited these
weaknesses through two key exchange sacrifices.
So one position the bishops gets assists and the other to make sure the bishops get into Essex.
Once that bishop got to Essex, the Knights were really dangerous with the Queen around the weaknesses
around the opponent's king.
So really fascinating game for weakness, provocation, and saying, come and get me an amazing kind
of counter-attack game.
So counter-attacks are often really powerful when opponents have committed their pawns and created irreversible
weaknesses.
OC has so much.
