Hi there.
In this lecture, we see Anatoly Karpov playing against Wolfgang Ullman.
In this game, we see a celebration of an open file.
So the general advice, generally speaking, belong on open files.
One of the reasons for this is that often works.
Say, on open files, they can infiltrate to the seventh Frank, and often the king resides on the eighth.
Still, statistically, there's a lot of pawns to win.
There's a lot of juicy targets.
So it's a good idea in general to try and leverage a file to get onto a rank.
So we see in this game E, four, E, six, four, D five.
So bear that theme in mind.
So that's often the fruit of getting rooks on file so nightly to the variation.
c5e takes, E takes.
Let's skip a little bit the opening phase.
So this is the transformation against the French.
So black has the isolated Queen's pawn generally, this gives black a little bit of activity.
We have Bishop G.
Five Black Castles, Bishop H four.
This is a standard maneuver generally aiming to exchange off the dark square.
Bishops Bishop G for Bishop E two.
Bishop H five Rookie one Queen b69 FD for Bishop G six and they'll C free Rook for eight and now Bishop
F one.
Bishop e for Bishop G three.
So we've got a nice middle game position here.
The Strategic Bishop Exchange tries to reduce the opponent's counterplay against the King.
The king looks pretty safe here.
We see a five and now a49 takes DD four.
And we do need some calculation here.
We don't want to play a routine move.
So what would you play in this position to maintain positional advantage for ten points.
So remove 29 takes the four.
So a tactical point.
Is.
I mean, we want to keep a blockade on D five.
Yeah.
If we take with the Queen, we're going to lose the knight and replace C takes.
We're going to lose our blockade.
So this is important to work out.
So if Queen takes B to the point is, what's the point here?
If Black takes on B two?
Yeah, we actually just trap the Queen like B five.
So we've got a rook e to France and we've also got a 97 threat.
So even if Queen seats two, we have queen size Bishop takes, we're winning the exchange.
We've got a winning position.
They're winning the exchange.
That's great.
Good news.
We can win from there.
And if you know Rook, let's look at rookie two.
That really does win the Queen.
The queen will have to give herself up.
So important point there.
So C six was played, but White has this good outpost for the bishop and Karpov first shows that because
of the outpost bishop, it's actually a little bit more secure than this guy and it's poking into the
black position.
At E!
Eight we have Rook 88 and now G for which the Prime is the bishop.
Bishop at five, sometimes if three sorry, instead of G four free Bishop F five as example.
And this is not as good as the game, it's just about even with G four, we want the bishop to be pushed
back.
A little bit further and to be a potential victim potentially with four and five.
So this is a prelude to try and victimize the bishop on E four.
We have 964 and Karpov doesn't mind here going into this situation where we haven't got the blockade
on D five anymore, we've got a slightly better bishop and we've got access to this seven.
Frank Potentially we see Rook, AC eight and our Free Bishop G six and our rookie seven.
So this is an interesting moment.
We have B six, very interesting moments.
Now if you put this through modern engines, Koppel doesn't play the top engine movie.
He plays like the second best move.
But the second best move is preventative move.
And from a human point of view, if we're a positional player, quite often we want to play moves that
are very crystal clear, easy to calculate, kind of simpler in nature because they're preventative.
So we want to accumulate advantages, but using prevention all along the way.
So it's like a non controversial accumulation of advantages.
You want games where you look at it with an engine after, okay, you might have not chosen the steepest
gradients playing the accurate move all the time.
Most accurate, but you choose a gradient which is small, incremental, but sure, going up that mountain
to win the game.
And here, what is the move that you will play, which is simple and effective?
And what is the more technical move which might you know, you need to calculate a lot more and human
calculation is fallible.
So when we use prevention, we're trying to compensate for the fallibility of our calculations.
So the famous Karpov Karpov quote about microscopic advances, if he had a choice between something
potentially unclear, but a bigger advantage or something much clearer but small advice, he chooses
a small advantage any time.
And here it's rook a one.
It's preventing any counterplay with rook two That rook is stuck at C eight Now we could play rook B
seven and yes, there's a finesse here.
This position.
We can secure the CFO so this position we can secure the C file with advantage.
That's another way of playing it.
But we need to factor in Roxy too.
And sure, if we can calculate like a computer, we end up with this position where there's a trade
of pawns like this and we have Bishop C six and it turns out in this particular position are past a
pawn is pretty effective.
Why?
It's definitely getting a bigger advantage here.
There's a tactic like Rook takes D five if needed.
If black plays Rook two, we've got Rook takes the five.
But who can calculate like this?
So Karpov's treatment is a more simple preventative move, saying that, look, if you play Rook C two,
I'm just going to make you.
So the rooks basically pinned down to that to the back row.
So H six is played to give the king air and we have now rugby seven in this position.
Rook D six if rook C two here, the difference is we can double rooks now and this position we can break
through with our outpost.
Bishop Guess what we play here for ten points.
We can actually play a beauty.
Remove Bishop eight and this is going to cause problems.
And you might think, Well, hold on.
What do we play here?
We can play for now, trying to rip through that seven Frank by nudging away the bishop and this position
we ripped through.
And we've got a great position here.
We're going to tear apart the king.
And you might think, Well, hold on, we've got trouble at home here.
Then we we get rid of that counterplay with Rook GCC seven with big advantage.
So basically, yeah, Rook C2 doesn't really work.
So we have rook D six.
Rook e seven.
H five.
If rook have six here.
King H two.
King H seven.
King G Free Roxy to the thing is rookie to in this position and white's getting a big advantage here.
So Bishop b5g6, rook C seven.
This should be one King of two.
One is a big advantage.
There if rooks c two rookie H king h seven and we can try and checkmate so let's say check and then
some air for the king on G six we have rook f eight.
This is a very accurate treatment.
And the idea here is basically we can go for the d five pawn at the very least in this situation.
So here Bishop eight Bishop takes F seven is quite vicious as well for Rook eight mating, there are
a lot of vicious opportunities.
So h five is tried.
We have comp of and doubling as pawns.
That's g for Bishop G six and F four trying to nudge the bishop away from f seven if Bishop e eight
that's not quite effective here.
There's rook F six and an F4 is disabled as well because of that rook f6 so F4 first and now rook C
one checking F two rook C two checking E free Bishop e four.
If rook have six, we simply play F five and then we're going to mate.
So Bishop E four we have rook takes of seven, g6g5, seven rook fee seven.
So this is interesting.
If Ruby eight that's also it's an interesting position here.
If Rookie six you know, this is generally a big advantage.
For whites here.
We've got a vicious possibility of playing Rook hate Shaq and Bishop Shaq.
And what happens now?
We're going to pin that rock.
Thanks very much.
So yes, it's great position for white and if Rook eats.
This is also another way of playing it for five, trying to get a mating net around the king, taking
out the G six square.
So check king of four.
And this position, Black's going to have to either give up the bishop or be mated.
Black has to give up the bishop.
So that's another way of using the eight franks and trying to make the king.
So yes, work f seven though, was played, which is simple and strong.
We have rook takes Beta and the point is Bishop eat here we have rook be free check king too.
If instead of rook be free check that was rook dd six then yeah, we use that seven Frank crash through
this position when threatening, mate.
It's pretty large advantage for whites, so.
Okay Rook, be free.
Check king e2 Rook b2 checking e one rook d6 If rook be one check, then the checks are going to run
out here.
And once they do, we're going to just take on G six.
Thanks very much.
So rook DD six rook tanks G seven checking H8 Rook G seven and Black actually resigned here at move
42 if Bishop f5 we play Bishop D seven.
So basically with Bishop dd seven we're threatening to checkmate.
What is black?
Do the checks run out here?
So for example, this position Bishop takes and then we can win the exchange.
But otherwise we're playing rugby eight mating.
So it's not very good options.
Or if Bishop eight seven we've got all sorts of things that we can take there and then take here.
So that's not helping either.
So yes, the game ended at Rook G seven, so a neat game.
Control counterplay showing the importance of the files.
The files are a start point to get the fruits of rooks on the seventh Nimzowitsch was a huge fan of
getting rooks on the seventh, so we treat files as a method to get rooks on the seventh.
They have to start somewhere.
Our Rooks, they start on the open files and it was enough here.
It's funny that the isolated Queen's pawn transformation into a different, more exploitable advantage.
It's more exploitable because we've got a relevant outpost for controlling eights, which is a file
we want to break into.
And it was also useful tactically, as we see in many examples for Bishop E8.
So yes, a very instructive example of well, why get our rooks to open files?
It sounds like simple advice.
Of course it depends on the situation.
Some situations it might not work.
You know, it depends on precise calculation of the positions quite often, but in general we get the
idea that our rooks, if they go on open files, they have opportunities for juicy targets on the seventh
Frank like this game.
So I hope you enjoyed this game.
Found it simple and effective Chess Okay.
And basically that's what we want to do.
We want to accumulate advantages non controversially and often it's a heavy use of prevention all the
time.
And prevention actually needs us to be sometimes very good tactically to see the possibilities of the
opponents so we can know what to prevent.
So we're using prevention all along the way to accumulate advantages and we get simple looking games
like this.
Okay, So much.
