Konstantin Sakaev GM Konstantin Sakaev annotates the games of the 6th round:




Adams - Anand 1-0
While the game Adams - Anand is developing originally.
Adams has an advantage after Bd7, probably will follow Rhd1 Bc6 Be4 (probably also g3 or f4) with idea Be4 Qe4 0-0 Rd7 Qh2 Rb7.
Strange move of Adams - 17.g3 Was stronger 17. Rhd1, as to take the pawn-h2 is very dangerously in view of 18. Be4 or 18. Bh7
Now here the position is close to the draw. I think Adams by move 17.g3? has lost the tempo and the advantage, which could be in case of 17.Rhd1.
Seems Anand has mistaken somewhere. After 34.Qg6 Black has the problems, for example Qc4 35.Qg7 and 36.Qd4.
Anand is losing. For Adams was better to play 36.Qd4.
Now Anand has the chances for the draw again.

In the game Ponomariov - Kasparov is a known theoretical position, some times already met in the practice of Kasparov.
The idea a2-a3 Leko applies frequently. White spends a tempo and weakens Q-side, but provides the position Knight c3. Quite viable idea, so began to play absolutely recently. f3-f4 is logically combined with a2-a3, White does not attack straight-forwardly the K-side by the pawns g and h , and combines with the play in the centre, taking into account a strong position of the Knight c3.
Ponomariov has a very perspective position. Usually in such structure to the Bishop on b7 not a place (especially before the Rook b8) and not so easy to move b5-b4 now. Seems White won the opening duel.
Ponomariov probably will play Qe3 (after a5).
In case of 17.Bc5 dc5 18.Qd8 Rfd8 19.Rd8 Bd8 20.Nb5 Be4 21.Be4 Rb5 the position is close to the draw.
After 17.Bc5 dc5 18.Nb5 Black has to play 18...Qb6 (badly 18...Qd2 19.Rd2 Be4 20.Be4 Rb5 21.Rd7)19.c4 Bc6 20.a4 White has an advantage.
18.Qd8 is a mistake. As I told now the draw is possible.
19.Nb5 instead of 19.Rd8 Bd8 20.Nb5 changes nothing. Now will follow 19...Be4 20.Be4 Rb5,that leads to the rearrangement of the moves.
Kasparov will play 23...g6,after Kg7 and carry out f7-f6 or h7-h6 and soon must be the draw.
The move 31.Rd7?! is very strange. Before that was the drawn position, and now White risks to lose.
A drawn game now all the same turns out, there will be Ra8 with the exchange of the Rooks and blockade the pawns f4 and g3.
Very risky looks now Bg2, although it's very interesting.
Ponomariov shows tremendous fighting quality. Taking into account, with whom he plays, 99 % of the chess players of the high level (admit, and me too) would force a drawn game by exchange of the rooks. The game for the win is connected to essential risk. Probably, he wishes to win very much. The game goes on three results!
Kasparov has now a choice to fix a draw by way of 44...g2 45.Bg2 Rg2 46.c6 Bd6 47.c7 Bc7 48.Ra7 Ke6 49.Rc7 f4 or try to play on a victory by 44...Rd3 45.c6 Bf6 46.Bg2 Rc3 47.Kb4 Here Black's chances is probably higher, but anyway perhaps also is draw.
After happened 44...Bc5 will follow 45.Ra5 and the draw is obvious.

The position and in the game Shirov - Vallejo Pons is not determined.
Seems Vallejo had to risk and to play 17...Re5. Now Shirov has a clear advantage.
Not bad look prophylactic moves 18.Kh2 or 18.f3.
Vallejo has a bad position and even difficult to propose the moves for him. And the play of White is simple g2-g3,f2-f4 etc.
The move 27.А5?! looked doubtful. White has begun to play on side, where he is weaker. More logical looked 27.h3-h4 with following h4-h5, grasping space on the K-side. Now the chances of Black on a drawn game look not so also is illusive.
Instead of 33.Nd6 White could still fight by way of 33.Ne3, and if 33...c5, then 34. Ke4, keeping initiative.
