7 The King's Indian Attack

(from White's viewpoint)

Mark Dvoretsky

A chessplayer who opens with 1 e4 may. if he wishes, include in his repertoire the system 1 e4 c6 2 d31? or 1 e4 c5 2 ФГЗ c6 3 d3 *?. Avoiding the French or Sicilian, White develops his pieces on the same lines as Black in the King's Indian Defence. In so doing, he hopes to gain not only from the extra tempo that results from switching the colours, but also from the fact that Black's ...е7-еб is not of great value here. (In the King's Indian Defence, White very rarely plays e2-e3.)

The same type of position results from Rdti's Opening - 1 £f3 d5 2 g3 c5 3 Д g2 Феб 4 0-0 - if Black plays ...е7-еб now or next move. (Incidentally, there are other formations for Black which also come under the heading of 'King's Indian Attack' provided that White develops his pieces on the King's Indian pattern.) But the present survey is based on my personal experience of this opening and takes most of its material from my own games - and I usually play 1 c4. So this move-order will receive most attention.

Some of the games given below are without theoretical significance since at least one of the players makes inferior moves in the opening.

Nevertheless, these games can still prove useful in acquainting you with the structure characteristic of this opening and the typical strategic and tactical ideas and precepts which are applied in it.

The material in this section is divided into three parts. The 'Main Line' is discussed on page 149 and •Black refrains from castling' on page 150.

In reply to the immediate 16 c4,1 didn't like 16...de 17dc£lb6 18 £d2 'йс4. The move played is an attempt to strengthen this plan - for example. 16...34?! 17 c4 ФЬ6 18 Sd2l. On the other hand after 16...ФЬ6, I imagined that the attack with 17 £}g5 would gain in strength.

However, White's idea is incorrect. Preferable moves were 16 ФЬ2 and 16 Ah3.

16 ... £b6

17 Qg5?

Played without due consideration. But then. Black was already threatening 17...d4.

Only now did I discover that all White's combinative tries arc easily refuted: 18 ЙЪ5 (18 £xf7 ФхГ7 19 ЙЪ5+ g6!) 18...hg 19 hg g6 20 «Ъ4 (20 «ЪЗ £xg5) 20...<£d4 21 £h2 €>f5 22 £xf5 ef 23 3h 1 Д f8 24 £g1 Д g7. or 21 £g4 2)f5 22 Wh3 Д xg5.

White's play has come to a dead end. With possibilities of ...d5-d4 or ...^d4 at his disposal. Biack is clearly better.
