We have seen, with the Nimzo-lndian and the Queen's I ndian defences, the strategic idea of controlling the centre by means of pieces rather than pawns. This idea is pursued in the King's Indian Defence also , after such moves as I d4 Nf6 2 c4 g6 3 Nc3 Bg7.
Instead of playing 3 . . . dS (the Grtinfeld) before White prevents the move by 4 e4 , Black chooses to prepare . . . eS himself by the modest 4 . . . d6 with the idea oflater exchanging his e-pawn for White's d-pawn , thus opening up the long black diagonal for his bishop. One of the most common systems arises after (4 e4 d6) 5 Nf3 0-D 6 Be2 (after 6 g3? Black has the strong reply 6 . . . Bg4 ! e.g. 7 Bg2 Nc6 8 0-D Nd7 ! 9 Be3 eS ! 1 0 dS Nd4 etc . , whereas now 6 . . . Bg4 7 Be3 N fd7 8 Re i ! or here 7 . . . eS 8 Be3 etc. sooner or later leads to the exchange of his useful dark-squared bishop) 6 . . . e S ! (See next diagram.)

Apart from this move and 5 N f3 , there are two other main systems : ( 1 ) 5 f4 (the Four Pawns Attack) 5 . . . 0.0 6 Nf3 c S ! (Black must

These two Jines show us . . . c5 as an effective way of increasing the scope of Black's dark-squared bishop ; the idea occurs in many variations.
The diagran1med position is the beginning of the Samisch System of the K ing's Indian Defence (we have already met one of Samisch's ideas in the Nimzo-l ndian Defence). White guards his e-pawn and prepares to develop a bishop on e3 (the immediate 5 Be3 allows 5 . . . Ng4) and usually castle on the Q-side, a similar set up to the Yugoslav system employed against the Sicilian Dragon Variation !
5 0.. 0-0
After 5 . . . e5 Black is not afraid of 6 dxe5 dxe5 7 Qxd8+ Kxd8 when White's control of the square d4 is weak, but White can reply 6 Nge 2 ! 0-0 7 BgS ! Pachman-Pilnik ( I 959) continued: 7 . . . c6 8 Qd2 Re8? (too slow, allowing White to block the centre and attack on the K-side . Black m ust play energetically : 8 . . .

If White now develops his bishop on gS, Black can play 6 . . . cS ! 7 d5 e6 with good prospects.
6 . . . eS
Because the results of this main line have been disappointing, other ideas have been tried here :
( 1 ) 6 . . . Nc6 (a modern idea , retaining the possibility of playing . . . e S whilst preparing Q-side action by . . . a6 , . . . Rb8, and . . . b S ) 7 Nge2 (not 7 Bd3 e5 ! 8 dS Nd4 or here 8 Nge2 Ng4 ! 9 fxg4 exd4) 7 . . . a6 8 Qd2 Re8 (if at once 8 . . . Rb8 then 9 Bh6 can be played) 9 h4 ! (if 9 Nc l e5 ! ) 9 . . . Rb8 1 0 0.{).{) with attacking chances for both sides down the h-and b-flles respectively . Black plays I 0 . . . b5 but not 1 0 . . . h5? I I Bh6 Bh8 1 2 g4 ! hxg4 1 3 h S ! gxf3 1 4 hxg6 fxe2 1 5 g7 ! exd l = Q+ 16 Nxd l winning.

7 dS (See next diagram .) c6
Black intends to open the c-file to counter-attack on the Q-side . Two other lines have been tried :
( I ) 7 . . . cS (?) gives White a free h and on the K-side : 8 Qd2 NhS 9 0-0.0 fS I 0 exfS gxf5 I I Bd3 a6 1 2 Nge2 bS 1 3 Rdg 1 ! bxc4
1 4 Bb l ! followed by g4 ! with a very strong attack.
(2) 7 . . . NhS 8 Qd2 fS

0-0.0 Nu7 (If Black plays 9 . . . f4 White will transfer his atten tions to the Q-side e .g. 1 0 Bf2 Bf6 ! 1 1 Nge2 Bh41 2 Bg l ! b6 1 3 Kb 1 aS 1 4 Nc 1 followed by b3 , a3 and b4 and eventually the thematic cS when his king can be well protected by his pieces) 1 0 Bd3 Ndf6 I I Nge2 K.h8 ! (an important move because if I I . . . a6 1 2 exf5 gxfS 1 3 Ng3 ! and Black has to play 1 3 . . . Nxg3 1 4 hxg3 , since 1 3 . . . f4 allows 1 4 Nxh5 fxe3 I S Nxf6+ Qxf6 1 6 Qe2 ! when Black's weak pawn will sooner or later be lost). Black's king move prevents the saving check (on move I S !) and chances are even.
8 Bd3 !
A natural and good move . The sharp 8 Nge2 cxdS 9 cxdS a6 1 0 g4 !? allows the interesting counter 1 0 . . . h S ! I I h3 Nh7 ! (threatening . : . h4 followed by . . . Bg7-f6-gS ) I I gxhS Qh4+ 1 2 Bf2 QxhS 1 3 Ng3 Qg5
1 4 Bg2 with unclear play . 8 . . . 9 cxdS
cxdS NhS(?)
We shall see that this move is no longer good enough , because Whi te already has the open c-ftle available. Black should either play 9 . . . Nbd7 I 0 Nge2 a6, waiting, when White must castle K-side, or else play here I 0 . . . NcS I I Bc2 a S ! with chances of equality, although White stands better.
10 Nge2 fS
Black prepares . . . e7-e5 I 1 8 1 After this blockade White will have a free han d to operate on the Q-side, but even after 1 1 . . . Nd7 1 2 0-0-0 White can always capture on fS followed by Ng3 or else play Rg1 followed by g4 .

Now White's knights con trol aS and b6, so he sets about exchanging the black-squared bishop to weaken the black squares even further.
After 22 . . . Bd8 23 Nb6 Bxb6 24 Bxb6 QbS 25 Bc7 ! Qd7 26 Re i threatening BaS and Rc7. Black is in as much trouble as in the variation played. 23 Rcl Qd8 24 N b6 Rb8 25 Bf2! Bxf2 26 Qxf2 N f6 27 a4! Bd7 28 Rc3 gS

The King's Indian Defence often arises (by transposition of moves sometimes) after White has fianchettoed his own light-squared bishop as in the following game :

Black prepares . . . e 7-e5 I 1 8 3 Black plumps for the usual King's Indian set-up. He can also play the
solid symmetrical variation S . . . dS 6 c4 c6 ! e.g. 7 cxdS cxdS 8 Nc3 Nc6 (or 8 . . . Ne4 )
9
NeS e6 ! Or 7 Nbd2 Ne4 ! 8 b3 Nxd2 9 Qxd2 BfS etc.6 c4
In this position Black has three main plans:
(1 ) 6 . . . c5 (the Yugoslav Variation) 7 Nc3 (or 7 dS Na6 8 Nc3 Nc7
9 a4 a6 10 Bf4 Rb8 1 1 aS bS 1 2 axb6 Rxb6 1 3 b3 eS ! 14 dxe6 N xe6 I S Bd2 etc.) 7 . . . Nc6 8 dS (after 8 dxcS dxcS 9 Be3 Be6 or here 9 Bf4 NhS 1 0 Be3 QaS chances are even) 8 . . . Na5 9 Nd2 ! e S ! 1 0 e4 Ne8 1 1 b3 fS .
(2) 6 . . . Nc6 7 Nc3 a6 (or 7 . . . eS 8 dS Ne7 9 c S ! opening the c-ftle . Or 7 . . . Bg4 8 dS ! Bxf3 ? 9 exf3 ! NaS 1 0 Qe2 etc.) 8 h3 Rb8 9 e4

Black's third method is the one adopted in the game, preparing . . . eS.
6 Nbd7
7 Nc3 eS
8 e4 c6
9 b3(?)
Jt is remarkable how dangerous this move can be, as a number of brilliant games have shown . White's best plan is either of these two ideas : ( I ) h3 Qb6 (or 9 . . . Qa5 , or 9 . . . Re8 1 9 De3 exd4 I I Nxd4 NcS
1 2 Qc2 aS etc.) 1 0 Re i exd4 (if 1 0 . . . Re8 I I dS !) I I Nxd4 Re8 1 2 Nc2 ! or here I I . . . Ng4 1 2 Nce2 NgeS 1 3 b3 NcS 1 4 Rfl ! and Be3 .

In compensation for his weak d-pawn Black has active play for his pieces.

After I d4 N f6 2 c4 Black has three other popular systems : A 2 . . . c 5 3 d 5 (the Hromad.ka System)
•
Black has four basic ways of meeting this :
( I ) 3 . . . e6 4 Nc3 exd5 5 cxd5 d6 6 e4 g6 after which White must play energetically e.g. 7 f4 Bg7 8 Bb5 + ! Nfd7 (after 8 . . . Bd7 or 8 . . . Nbd7 then 9 e5 is very strong) 9 a4 ! (to prevent the advance of Black's Q-side pawns) 9 . . . a6 1 0 Bd3 0-0 I I Nf3 followed by 0-0 and White stands better.
(2) 3 . . . e 5 4 Nc3 d6 5 e4 Be7 6 Nf3 (or 6 g3 , or 6 Ne2 and Ng3 ) 6 .. . 0-0 7 Be 2 Bg4 ! 8 0-0 Bxf3 ! 9 Bxf3 Ne8 ! followed by . . .
Bg5 and Black achieves equality.
Black prepares . . . e 7-e5 J 1 8 7
on the Q-side e.g. 4 cxb5 a6 5 bxa6 Bxa6 6 Nc3 g6 7 e4 Bxfl
S Kxfl d6 9 Nf3 Bg7 I 0 h3 0-0 I I Kgl Na6 1 2 Kh2 Qb6 followed
by . . . RfbS. Practice has shown how difficult it is for White to exploit his material advantage.
(4) 3 . . . d6 . Black waits, retaining the above options, but usually breaking later in the centre by . . . e6 and thus avoiding variation 1 . The continuation might be : 4 Nc3 g6 5 e4 Bg7 6 Be 2 0-0 7 Nf3 e6 (or . . . e 5 ) S 0-0 exd5 9 cxd5 ReS etc .
