9 h3 AhS

17 h4 £xf3 While threatened to win by 18 g4

and 19 h5, but preserving the bishop with 17 Ag6 may have been a lesser evil

20 Wc2 *a5

This is the type of position White was aiming for with 8 Set Unlike French Defence-related positions Black has his queen's bishop outside his pawns, but the cost of this luxury is a delay in beginning the thematic queenside attack White, meanwhile, is able to play in the classic KIA style

11 an aC7

A similar position arose in the game Todorcevic-Lukacs, Rome 1988 After 1 £>D d5 2 g3 <Sf6 3 Ag2 c6 4 d3 ¿g4 5 ftbd2 (a clever move order which guarantees to keep a knight on 13 should Black decide to give up the two bishops) 5 e6 6 0-0 Ae7 7 h3 Ah5 8 e4 0-0 9 abd7 10 Sel a5 11 e5

£>e8 12 afl ac7 White played 13 g4' Ag6 14 ag3 h6 15 lf4 b5 16 B,d2t c5 17 g5r with considerable pressure on the kingside

12 aih2 a5

Also to be considered is 14 a3 to prevent any weakening of the dark squares

Black has little time for such a provocative move Better is 15 c5 followed by b5-b4 and only then aC7-b5

Consistent with Black's plan of dark-square pressure Now, tnstead of 22 axd4? allowing 22 axe5, White prepares to infiltrate on the kingside and subsequently force either g7-g6 or h7-h6

22 We2 Ac3

23 ag5 g6

24 h5

A typical pawn thrust in this opening, serving to open the h-file when the time is right

25 %4 2fe8

27 ae4!

With this move White shows that, despite exchanging his dominant knight for its passive counterpart, the attack will proceed unhindered Indeed Black can only try to regroup and wait for the invasion

29 ig2!

Clearing the way for the White rooks to join in the attack

30 Wg4 Sa5

31 hxg6 fxg6

An even more immediate end would result from 31 hxg6 as White could simply double on the h-file The move played puts up more resistance, but Black's position is by now far from invulnerable

41 Wc8+ 1-0 Black's queenside play came to naught

Forcing decisive material gain

There is nothing wrong in playing this standard move so early

7 e4 dxe4

8 dxe4 e5

Korchnoi takes advantage of the extra move caused by Black's e7-e6 followed by e6-e5 Now, thanks to 6 Wei. White threatens 11 &fxe5

The English GM tries to revitalise his game by introducing a theoretical novelty 11 Ae6 12 ¡ht5 is clearly bad for Black, so giving up the bishop pair with II ¿xe3 12 Wxe3 is the lesser evil, with an advantage to White The game now takes on an unusual character for this variation, and the reader would be well advised to see how former

World Championship challenger Viktor Korchnoi shows us the KIA is indeed aptly named — wherever Black's king hides' 12 a3! 0-0-0 (D)

Faced with the dismal prospect of 23 bxc6 24 Sab I Ab7, Black decides to complicate matters
