Sergey Ivanov GM Sergey Ivanov annotates the games of the 3rd round:



Kasparov - Anand 1/2
Today we await the next " fight of giants ". Last years Vishy extremely unsuccessfully played against Garry, but in their previous game - on last year's Wijk aan Zee he had a good opportunity to improve the statistics. Let's look, that will turn out this time.
The same variant, as in the game of the first round Shirov-Anand is played. Similar, Anand seriously considers this variation of Paulsen system as the mean for suppression of a fire heated on a board by the chess players with sharp style (we shall remind, the book of Shirov has title - " Fire on the board "). As well as with shirov, Anand uses the continuation 13... 0-0 (more is common 13... c5 14. Be5 Rb6, as Anand played against Kasparov in rapid chess tournament in Frankfurt, 2000). But, Kasparov at once throws forward the pawns - 14.e5 Nd5 15.А4. On 16th move White has preferred to keep the light-squared Bishop (16. Bf3), met 16.g3 Ne2 17. Qe2 c5 18. Bc3 f6 19. Rad1 White has an advatage (Tseshkovsky -Tregubov, Krasnodar 2000). It is obvious, that e5-pawn strongly constrains Black, and he is obliged to undermine it by f7-f6. But this having undermined is necessary for preparing (17... Ng6), as at once 17... f6 it is unsuccessful in view of 18.ef6 Bf6 19. Bc5! Bb2 20. Bd6 Qd8 21. Rb1, and White win an exchange. But now on the change pawn "e" comes the pawn "c" (18.А5).
20.. Nf4 - it was possible and at once to exchange the bishops: 20... Bd4 21. Qd4 Nf4 22. Rad1 - White all the same keeps the certain pressure. 22. Qc2 - it is useful to cause weakening of the pawn covering of the black king. After 23. Rad1 - White stands slightly better. His pawn structure is better and the pieces are better coordinated, the opportunity for play is kept on all board. The position of Black strong, but passive.
26. Re2! - best place for this rook, where it defences the 2 line. And another rook begins to maneuver on 4-th horizontal (27. Rd4). 27. Bh7!? - too useful intermediate move, the Bishop on e4 has nothing more to do, and the position of the king in a corner of a board can sometime to have an effect. 29... Qf6 - Black it is necessary as soon as possible to return rook on Q-side, for defenc a5-pawn. After 31... Qd8 - Black while all havedefenced, it is necessary for Kasparov to search for new objects for attack. Now arises pawn attack on K-side (h2-h4 etc.), probably, it will be possible to loosen the position of the black king.
Something strange happens in the end of the game. On the official site appeared only two moves and if there is no mistakes... On the 33th move Black quite could take the pawn: 33...Rc5, and after 34.Rh6 (34.Qd4 Rc1) 34...gh6 35.Qd4 (there is no mate after 35.Qh6 Kg8 36.Re5 Kf7, but White has not the Rook) 35...Qf6 36.Qc5 the game is unclear. Meanwhile in case of 33...Qf6 it is unpleasant 34.Qc2! Kg8 35.Qh7 Kf7 36.Rg4 with attack. And after the move in the text 33...Qe7 White has a possibility 34.Rh6! gh6 35.Qh6 Kg8 36.Re5 Rc5 37.Rg5 Qg5 38.Qg5 - taking back the Queen and the attack is continue. Is it possible that here was an agreement on a draw?!
There were mistakes in transmission of moves on the official site. No is Okay.
So, it seems Anand have made a blunder, Black was forced to play 34...Kg8. He is a pawn less and his King is under attack. Perhaps Kasparov also didn't expect such an occurrences and committed an inaccuracy at once: instead of 35.Rh4 stronger was 35.Bh7 Kf7 36.Bg6! (a key point for the Bishop) 36...Kg8 37.Rh4 Rab8 38.Re5 Rb2 39.Qd4 - Black has a hard position.
In the game Black with a timely counterplay 38...Rb2! has got sufficient counter-chances and Kasparov preferred to fix a draw in already rather unclear position.

Shirov-Adams 1/2
The Ruy Lopez is played. With Adams now few who ventures to go on Marshal counterattack, therefore "anti-Marshal" (8.a4) even "from the hands" of Shirov looks naturally. On 9-th move Adams has selected tricky 9... Re8!? (usually play 9... d6) - Black intend to save the tempo and to play d7-d5 in one move. And in case of 10. Ng5 will follow 10... d5! 11.ed5 Nd4 12. Ba2 ( 12.d6? Nb3 13.de7 Qd5! - +) 12... Nd5 13. Re5 Bg5 14. Bg5 Qd7 Black has an advantage (Zapata-Nunn, Dubai 1986).
Shirov has played in the best way - 10. Nc3, but it is possible, further it was necessary at once to remove the Bishop - 12. Ba2!? Only so White can struggle for the advantage, exchange on e7 has allowed Black to carry out planned d7-d5 and to solve all opening problems. Because in a case 14.ed5 will follow 14.. Qd6, and the difficulties can be only at White.
On 17th move Shirov has prefered to exchange on f6, depriving himself of advantage two Bishops. But in case of 17. Bh4 it is necessary to be considered with 17... g5 18. Bg3 Qc5 with counter-play, is weaker 17... b3 18. Bf6! Qf6 19. Bb3 Nb3 20.ab3, and Black has no complete compensation for the pawn (Huebner-Polgar,Bil 1987). To the 18th move the position was completely equal.

Vallejo Pons - Ivanchuk 1/2
In an opening a curious transformation has taken place: Black has offered Alekhine, White has rejected the offer and there was a Vienna , passed into the four Knights, in which White has selected variant 4.g3. In development of this system the large contribution has brought Russian-German GM Igot Glek.
It is necessary to tell, that construction of White reminds that happened with Vallejo in the 1-st round in the game with Garry Kasparov.
The contenders rather originally treat this scheme. So, White refuses from standard manoeuvre Be3, and Black begins pawn attack on the Q-side. 10. Kh1!? - an artful move, White beforehand prepare to possible f2-f4. After 12. Bh4 it is obvious, that is bad 12... g5? because of a standard sacrifice 13. Ng5! hg5 14. Bg5 +-. And on the following move 13... g5 badly in view of 14. Ng5 hg5 15. Bg5 Bd5 16.ed5 Na7 (16... Nd4 17.c3 Nf5 18. Qf3 +-) 17.f4! (where the move Kh1 was useful!).
15.. ed4 - black it is necessary "to kill" the own Bishop, as in a case 15.. Bd4 16.c3 Ba7 17.f4 White develops the strong initiative.
After 16th move it is possible to ascertain, that Black has not achieved the equatation, White has two Bishops and his pieces are located more harmoniously. Instead of 17. Re1 deserved attention also 17. Qf3 g5 18. Bg3 with opportunities of active play on K-side. 19.. Bb4 - by everything, unsuccessful decision. Pawn a5 now will be for Black source of a headache. It was necessary to play 19... ab4 - is accurate being defenced, Black should make a drawn game. Probably, Ivanchuk has underestimated retort 20. Qc1!, in a case 20.c3 Bc5 21. Qd2 Bb6 at Black everything is defenced. 20.. Rb5 - looks clumsily, and what to do? On natural 20... Ra8 will follow 21.c3 Bc5 22.b4! with idea 22... ab4 23. Ra8 Qa8 24.cb4 Bb4 25. Bf6 gf6 26. Qh6 with attack (as it is visible, Queen on c1 plays not only on Q-side, but also on K-side). But also now after 21.c3 Bc5 (to not play 21.. Rc5 22.c4!, and thr rook is arrested) 22.c4 Black loses the a5-pawn, as in case of 22... Rb3 23. Ra5 it is impossible 23... Rd3? 24. Qc2. After 23... g5 24. Bg3 Qb8 Black all the same takes back the pawn, but by the price of serious weakening of K-side.
25. Bf1?! - all back. It's not clearly, why Vallejo has not played 25. Qd1, for example: 25... Rb2 26. Qf3 Rb1 27. Kh2 Kg7 28. Qf5 - the position of Black is very dangerous, threatens h3-h4 with destruction of K-side. And after a shy move by the Bishop and subsequent exchange of the rooks the position was became equal, and soon agreement on a drawn game has followed.
Despite of a number of the unused opportunities, it is necessary to note, that the young spaniard Vallejo Pons is looked while not bad very much.
