hi everyone this is Grandmaster Eugene Perelstein

and together with Chess lecture.com

I'd like to welcome you

to the second part of the lecture

King's Indian against the 4 pawns

attack from Black's perspective

let's begin

d 4 knight of 6

c 4 g 6

knight c 3 bishop g seven

e 4 d 6

so black is playing the King's Indian defense

and now white is to choose which system to employ

f four

this is the 4 pawn attack

the most dangerous variation

against the King's Indian defense

so let's continue now black and Castle or play C5

which usually just transposes

so let's see castles

knight of 3 and c 5 so in the first lecture

I talked a little about d take C

and now the key move is queen a five

you see you create a threat

Knight takes e 4 and white has to play bishop d 3

then you're captured with the queen stop in castle

and then you simply develop with knight to 6

on bishop g 4 and very good active piece play for black

so this line is not a problem at all

so let's go back and the main move here is d 5

White closes the center and takes

takes up even more space

so we play e six

and now the main line is bishop e 2

again I also mentioned in the first lecture what to do

after d takes e

Black has a pleasant choice

between bishop takes and pawn takes

I prefer to take with the pawn to cover the d 5 square

and then after bishop d 3 knight c 6

you simply have a good square on d 4

no weaknesses and very good plan for black

so let's go back Bishop e 2 e takes d

C takes d

now E takes d as I mentioned has no venom at all

and after bishop f 5 excellent play for black

so C takes d we are now

reaching the critical position of the opening

and very important is

to focus immediately on the pawn structure

you see that the pawn structure is fixed

white has a powerful pawn structure in the center

close to to the king side with the f 4

e 4 and d 5 whereas black has a very small

defensive setup with d 6

c 5 in the center and very powerful

pawns on the queen side

and possible break through with the b 5

b 4 whereas white of course

will break through in the center with e 5

so these are the plans

so black plays Bishop to g 4

this is very important move remember that

his position is a little bit less space

therefore we wanna instead of playing night B d 7 first

we wanna exchange at least a bishop for the night

on f 3 this way

we actually have much easier way for our pieces

so after Bishop g 4 castles

knight b d 7 Black has finished his development

sooner or later

he's gonna take on f 3 and have a good game

so now after rook e 1

White creates a very interesting threat

and the threat is e 5

so for example if black plays a move

A6 would I get to play B5

he gets into trouble after E5 immediately

now if Bishop takes a 3 simply Bishop takes a 3

and now white is running

through the center with the two bishops

and just position is way too powerful

so let's go back

and the key move here is very simple

Bishop takes knight and after bishop recapture

simply drop back with your knight to e 8

and all of a sudden

it's not so easy for white to play e 5 anytime soon

because we got the bishop

the knight and the pawn on looking at e 5 square

where is white has a lone soldier

the rook on e 1 defending the pawn and the pawn on f 4

so let's actually look at the game

which occurred in this very position

where black played a well known grandmaster

Igor Alexander Nataf from France

this is a recent game from 2007

against a 23 player at a recent tournament

Canadian Open

so after this move night e 8

Black of course wants to play night e 7 on b 5

and immediately get counterplay on the queen side

at the same time he opens up his bishop on g seven

you see all of these moves make sense

and also pay attention

that black doesn't have that lingering bishop on c 8

which doesn't do anything

and it's exchanged for the knight on f 3

which actually did play a role in attacking the square

and defending the pawn on e five

so now Bishop e 3 well

white has to develop right

and simple move knight to c with idea to play b five

white plays a 4 by the way

e 5 pawn sacrifice doesn't really achieve anything

after d takes e d 6

Knight e 6

Bishop takes b 7 and now after simple rook b eight

Bishop has to retreat

then black captures the pawn on a 4

hitting the bishop they be two pawns weak

overwhelming advantage for black

so let's go back

and continue with a 4

again very simple idea is to stop B5

so now natav could have played a 6

but I like the more prudent way to first play Rook e 8

completely stop e 5 won't sacrifice from ever happen

you get an extra piece on e five

and all ideas with e 5 for white fail

so bishop f 2 a reasonable move

possibly bringing the bishop to support e 5

push on g three

and now of course black follows up with his plan

which is a 6 b 5

notice that the structure is very similar to Benoni

where

black also usually changes the light square bishop

and continues with a 6 b 5 on the queen side

so if you play Benani is black

you usually get a similar type of play

so after Bishop f two

we simply play a 6 the idea B 5

now queen d 3 was played in the game stop in B5

but besides queen d 3

White probably has some other choices

and one of them is bishop to g three

so let's take a look at this move and see what kind of

positions could arise

so first let's look at b 5

a natural looking move

and see if black can play b 5 right away

so after a takes b

we can recapture with the knight or the pawn

so first let's look at the pawn recapture

so after pawn takes Rook takes a 8

Queen takes e 8 and of course e 5

this is the key move

and notice that now queen on a 8 is misplaced

after e takes d the 6 wins a piece for white

so black has to be very very careful

probably after e 5 his only chance now is to play b 4

but you know these complications might not be in

in Black's favor at all for example

even I e 4 after E takes d 6

I really don't like Black's position

black is in trouble

so again

you have to be very careful and always watch out

for the e 5 move

so that's why instead of b 5

I would prefer to play rook b 8 first

not given white any counter play

having the black queen displaced on a 8

if e 5 now well we just simply take d 6

night d 6 and really black is doing great

because if pawn takes e 5

we can play night d four

look how powerful the knight is on d 4

it controls the whole board and the e 5 pawn is doomed

and now the possible continuation could be night d 5

and now we can even play night takes e 5

secondly exchange after 97

Rook takes pawn takes

queen takes

and now we have two pawns for the exchange

the knights are just overwhelming in the center

and black has more than enough

compensation for the exchange

so let's go back

and definitely e 5 is not an option here for white

so let's see what happens after a 5

with the simple idea to stop b 7

b 5 pawn push

well

here actually we have a pleasant choice to play b five

with actually similar plan

as we're gonna see in the next half game

or another move is night b 5

you see black has a different

two different plans in this position with night b 5

night takes b 5 a takes B

we actually open up our bishop

and create a very nice pawn storm

on the queen side and if queen be 3

we actually transposed into one of the games

by Ukrainian grandmaster Oleksenko

and now the moves b 4 followed by b 7

b 5 with the same type of plan

I think the original game went rook e two

b 5 a takes b

queen takes b 6 queen c 4

and now the key move queen c seven

with ID night b 6 king h 1 night b 6

killing the queen queen b 3

and now c 5 c 4

an excellent move queen takes b 4 and I d 5

and black is doing amazingly well

so old ideas such as B5 and I B5

you have to keep in mind

but the most important part always

always pay attention to the move e 4

e 5 pawn sacrifice for white

this is actually White's only active plan

in this position

so after rook b 8 black is doing really good

so let's go back to the actual game

so queen d 3 simple idea to stop b 7

b 5 and of course rook b eight

so in this position white played a 5

let's take a look at e 5 pawn sacrifice here

well

I don't see what changed after simple e takes d

d 6 Knight e 6

Black continues to dominate a force hanging

and if white takes the knight takes hitting the queen

so you see

white has no compensation at all for the sacrificed

pawn

so white is not doing that great in this line

that's why he has to play a 5

and we are following the not off game so far

and of course night b 5 is not possible this time

but b 5 the thematic pawn storm on the queen side

is the key to opening up files in this position

so white

can't really not take on b 6

because moves such as c 4 and b

4 are looming in the air and after a takes

B not up correctly took with the rook

well you might ask why not with the knight

the reason is knight on b 6 doesn't really do anything

and furthermore it weakens control over the e 5 square

and no longer defends the c 5 point

and now move e 5 is really

really powerful

so you see

black has to play precisely and take with the rook

not only does the rook attack the b 2 pawn

it plays an important role when it's gonna go to B 4

and support Black's army

and attack in the center and the queen side as well

so now we can actually stop here and review the opening

black has

created

enough counterplay for his pieces on the queen side

whereas white didn't achieve anything furthermore

has never

really had any chance to play E5 from this position

so now it's white who is on the defensive no

no even though he has two bishops

but they are both sort of useless

the one on f 3 just looks at his own pawns

the one on f two

is completely out of the queenside game

because the bishop on g

7 is probably twice as powerful as the bishop on f two

where is black snipes play important roles

one is going to B 5

and the one on d 7 keeps an eye on e 5 square

and really holds the position together

so white plays Rook a 2 defending the pawn

and now very strong move for rook b 4

you see how all of Black's pieces are playing together

Knight b 5 is gonna come in

Queen b 8 is gonna come in or even c 4 pawn push

so many plans

and black has clearly taken over the initiative

and I can understand why it's frustration

and he really doesn't have any counter plan

he plays E5

he decides to burn all his bridges and says

ah what the heck

I'm gonna create counterplay

at the cost of the pawn or two

but I have to create counterplay period

so Natasha acts correctly

d takes E he's not afraid to win material d 6

and now Knight e six

the pawn on d 6 could be trouble

but the knight on d

7 does a very good job of blocking it

while all of Black's pieces are perfectly placed

to repel White's storm

and actually gain material in the meantime

so 95

White has to do something actively and he plays 95

hitting the rook and now simply night takes a 4

hitting the queen and queen takes a six

so in this semi sharp position

white did open the position somewhat

at the cost of 2 points now is this enough

my guess is probably no most likely

black has more than enough for the 2 points

that white game I mean that black game

and white doesn't have any compensation whatsoever

after night takes d 5 Bishop d 5

and this would actually happen in the game

the only target white has is the pawn on f 7

a powerful bishop on d 5 but that's about it

black has on the other hand

two pawns and himself is gonna go on

on offensive after the move e 4

and this is what was played in the game

a really really good move opening up the bishop

and potentially what I'd do to play bishop d 4

and actually go after white king

because now black has a pass on e four

and after Queen A7

Natasha actually played Bishop D4

and I prefer black by far

2 pawns

excellent position and very good pawn structure

and actually 2 pawns up any endgame black is winning

so here I'd like to stop and evaluate this position as

in favor of black

and let's go back and review the 4 pawn attack

once again

to make sure you understand all the

little nuances of this opening

so d 4 Knight f 6 c 4 g 6 Knight c 3

Bishop g 7 e 4

d six and F4 is the four point attack

against the King's Indian

again here we can play C5 or Castle

both of these move are moves are equally good

and they usually transpose night of 3

the key move here is c 5

you attack the center with the c pawn

unlike the typical King's Indian

where usually attack it with the e pawn

the main line is d five

d takes t is not as powerful after queen a five

and now the key move is E6

you undermine the center immediately

because you don't want to keep the E4 d five c 4 points

in the in the center so after e 6

the line is bishop e 2 E takes d C takes d

and now the key move is bishop g 4 again

it's important to exchange

the light square bishop for the night of

on f three

for two reasons Black's position is cramped

and second of all

the knight on f 3 plays an important role in the e 4

e 5 push

castles Knight b d 7 rookie 1 well

you might ask yourself a question

why not e 5 right away

well

we can simply take on f 3 and if bishop takes on f 3

we win the pawn

and if e takes f

then this little line

takes the rook

queen takes of course favorite is black

you got a queen and a pawn for the rook and bishop

which is plenty should be winning for black

alright so this is very important

that moves like that don't work

the tricky move is rook e one

with idea e 5 and immediately I recommend you to take 1

f 3 and play knight e 8

and now e 5 is no longer dangerous

and the plan is knight c seven

with b 5 and so after bishop e 3

I don't see anything better for white with development

Knight c 7 a four

simple move Rook e 8

bishop f 2 and now a 6

and black is doing amazingly well

and after possible queen d 3

Rook b 8 a 5

b 5 is the key and if

why doesn't play queen d 3 and plays bishop g three

Rook b 8 a 5 knight b 5

I like this move I in the d 4 square

and after knight takes b 5

a takes b queen b 3 b four

and again Black's pawn structure is just so good

and White's main problem he can never play e 5

otherwise what to do e 5 simply loses a pawn

my lecture on the four point attack

in King's Indian Defense

and for you it's most important to remember ideas

idea in this type of position is black

exchanging the bishop on F3

plays knight e 8 knight to 7

always you gotta watch out for the e 5 pawn break

and most importantly a 6 through b 8

b 5 there is really nothing

that white can do to stop the counter play

on the queen side

and I think maybe this is the reason why

the 4 point attack is no longer popular on the GM level

and it's been replaced by the classical approach

with knight f 3

or the Zemisch f 3 lines at the grandmaster level

which we're gonna look at sometime in the future

thank you very much and I hope you enjoy these lectures
