Unlike cheaters

Unlike cheaters, the strongest grandmasters of the World make quite a lot of mistakes.

Here is a fragment from the book:

"Inside the main game there are two fragments inserted in which Black also experienced some problems.

52. Ivanchuk,V (2768) - Sutovsky,E (2700)
FIDE World Cup 2011 Khanty-Mansiysk RUS (3.1), 03.09.2011

1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.f3 e5 6.Nb3 Be7 7.c4 a5 8.Be3 a4 9.Nc1 

The knight starts his trip on the route Nb3-c1–e2, later - depending on the circumstances. 9...Qa5+

[9...Be6 10.Na3 Nc6 11.Bd3 Nh5 12.Ne2 Bg5 13.Bf2 Qa5+ 14.Nc3 Nf4 15.0–0 0–0 16.Re1 Qb4 17.Bf1 Nd4 (17...Qxb2 18.Nab5+/=) 18.Rb1 Bd8 19.g3+/= 1/2 Lima,D (2525)-Dominguez Perez,L (2534)/Merida 2000); 9...Nc6 10.Bd3 Qa5+ 11.Qd2 Bd8 12.Ne2 Be6 13.Na3 Bb6 14.Qxa5 Bxa5+ 15.Nc3 Ke7 16.Ke2 Nd7 17.Nd5++/= 1–0 Mastrovasilis,D (2567)-Vouldis,A (2521)/Ermioni 2006] 

10.Qd2 Rather rare (in the given pawn structure) example of queens' exchange. It became real because of the knight's route, as usually it occupies square d2. To whose benefit is it? The white king seems to be not badly arranged in the centre. But at full board he will be open to the attack later. 10...Bd8 11.Ne2 Be6 12.Na3

Please, don't be surprised, the unwritten rule "on the edge of the board knight is badly placed" is not so timely here. The negative of the swift а7-а5-а4 lies in weakening of the control over square b5. But especially there the white piece is aimed to take place. Moreover, the sly runner is ready to occupy square с4 when occasion  offers (after c4:d5). 

12...Qxd2+ 13.Kxd2 Ba5+ 14.Nc3 Having switched from poor stand b3 to the active c3 the knight feels fine. 14...Nc6 15.Nab5+/= 

Later you will be more than once convinced that it is put very often here. A good square, as from here it controls points d4, d6, c7,c3... And it's difficult to chase the horse away because a-pawn has run ahead and c-pawn is initially absent in the Sicilian Defence. J 15...Ke7 16.Be2 Rhc8 17.Rhc1 Yes, in similar structures it's more reasonable to put on c1 this rook exactly, because fighting is going on queenside, as a rule. Besides, the white king which afterwards retreats to the 1st rank won't disturb anybody. [17.b3] 17...Bb4 18.Rab1 Nd7 19.Ke1 Bc5

 Thematically, you will also see alike manoeuvres in many games. It's a natural Black's wish - to trade dark-squared bishops. Then black points of the opponent (d4, e3...) will be weakened. [Pressure on с4-pawn, by no means forces the weakening b2-b3, for instance 19...Na5 20.Bd2 and not good 20...Nxc4? 21.Nd5+ Bxd5 22.Bxb4 Be6 23.b3 axb3 24.axb3+/=] 20.Bf2 Na5?! [More solid 20...Bxf2+ 21.Kxf2 Na7+/=] 21.Nd5+ Bxd5 22.cxd5 g6 23.Bh4+ 

Typical bounce applied by White in such pawn structures periodically. Sometimes it's auspicious to save bishops 23...f6 24.Kd2 [Looks more definite 24.Bd3!? with the idea to put the king on e2, then dark-square bishop could use squares e1 and f2. Bishop d3 would prevent programmatic f6-f5] 24...g5 25.Bg3 f5!? Here Black obtains counterplay 26.exf5 Nf6 27.Nc3 Bb4 28.Kd3 [28.h4] 28...Rc4 29.Bf2 Rac8 30.Be3 As far as I remember, time-trouble was already raging with all ensuing consequences. [30.Kc2] 30...a3?

[Right 30...h6] 31.Nb5? [Looked vigorous 31.Ne4! Nxd5 32.Bxg5+ Kf8 33.Rxc4 Nxc4 34.bxa3±] 31...axb2 32.Rxc4 [32.Rxb2 Rxc1 33.Rxb4 unclear] 32...Nxc4 33.Bxg5 It is hard to evaluate the position exactly. Only the white king's discomfort under the fire of enemy pieces can be definitely stated. 33...e4+! 34.Kd4 Na3

Crucial moment 35.Nxa3? [It was quite possible to hold the line 35.Bxf6+ the only move Kxf6 36.Nxa3 exf3 37.Bxf3 Bxa3 38.Be4=/+] 35...Bc5+! Murderous intermediate check. At the presence of f6-knight (though pinned but alive) the king can't capture e4-pawn. 36.Kc3 Bxa3+ 37.Bc4 [37.Kb3 Rc1 38.Bxc1 bxc1Q 39.Rxc1 Bxc1–+ Great deal of white pawns can hardly rescue. As the opponent is absolute monopolist on black squares] 37...b5 38.Kb3 bxc4+ 39.Kxa3 c3 40.fxe4 Rb8 

The titanic struggle of chess gladiators represents a considerable number of mistakes even on such a great level. That's why when players with ELO rating below 2200–2300 deliver games about 60 moves up to the "Houdini" first line (in recent years it happens more and more often) unwitting doubts creep in.  0–1 "
