Kasparov - Ivanchuk
Linares 1999
1.d4 d5 2.c4 d:c4 3.Nf3 e6 4.e3 c5
5.B:c4 a6 6. 0-0 Nf6 7.Bb3 Nc6 8.Nc3 c:d4 9.e:d4 Be7 10.Re1 0-0 11.a3
Na5 12.Bc2 b5 13.d5! Nc4 14.Qd3 Re8!
A direct attack now appears to be
natural, but 15.Ng5 e:d5! 16.N:h7 g6; 15.Bg5 N:b2 16.Qd4 Bb7; or
15.Nd4 Bc5 fails to support to white’s wish to blow black apart.
After deliberating for an hour, Kasparov concluded that the game
should be handled along positional channels. Instead of looking
for targets to attack and calculating variations, he switched to
scrutinizing positional elements like weak and strong squares.
15.a4! e:d5 16.a:b5 a5 17.b3 Nd6
18.Nd4 Bb7 19.f3 Rc8 20.Na4 Bf8 21.Bg5 g6 22.Qd2 R:e1+ 23.R:e1
White holds an edge, which he went on
to consolidate.
Black resigned
on the 36th move.
Leko - Carlsen
Morelia / Linares 2007
1.d4 Nf6 2.Nf3 e6 3.c4 b6 4.g3 Bb4+
5.Bd2 B:d2+ 6.Q:d2 Ba6 7.b3 0-0 8.Nc3 d5 9.c:d5 e:d5 10.Bg2 Re8 11.Ne5

Rad8 18.Rac1 Qe7 19.d:c5 b:c5 20.Qa4! Rd7
With accurate and strong play, white
has achieved a considerable advantage, as black’s pair of hanging c
and d-pawns are clearly more of a liability than a strength. Black’s
set-up, occupying the breadth of his second rank is amusing, but
hardly serves a practical purpose.
With 21.Qa5 (21.Q:a7?! Ne6 is
unconvincing) white can keep up everything under control. With his
next move, suddenly all hell is breaking loose:
21.Ne4?! d4! 22.e:d4
22.N:c5? d:e3! and the tables are
turned.
22...B:e4 23.B:e4 Ne6!
The Norwegian wonder-boy is quick to
grasp his chances. It turns out that 24.Bc6 R:d4 25.R:d4 N:d4 26.B:e8
Ne2+ 27.Kf1 N:c1 is far from clear. Instead of dictating the pace,
white finds himself having constantly to thwart concrete threats. He
is up to the task, though.
24.d5
Nd4 25.Re1 Qd8 26.Kf1! Rde7 27.Bd3 Qc8!
The threat 28...Qh3+ is hard to meet;
29.R:e7 Qh3+ 30.Ke1 (30.Kg1?? Nf3+) R:e7+ hands black a powerful
initiative.
The first 20 moves went smoothly for
white, but as the situation had transformed, concrete calculation is
now called for.
28.g4!
Chess players are loath to execute
such ‘ugly’, weakening moves. However, despite appearances, it is
winning. 28...Q:g4? is obviously defeated by 29.Q:e8+!.
28...R:e1+ 29.R:e1 Rf8
The following phase really combines
the two parts of this article. Now it is finally possible for white to
restore calmness and solidity into the position!
30.h3 Qd8 31.Be4 Qb6 32.Bg2 g6
33.Kg1
Now white is not just a pawn ahead; he
is a healthy, safe pawn ahead!
White won
on the 53rd move.
