[Event "Candidates 2016"] [Site "?"] [Date "2016.03.17"] [Round "6"] [White "Anand, Viswanathan"] [Black "Svidler, Peter"] [Result "1-0"] [ECO "C88"] [WhiteElo "2762"] [BlackElo "2757"] [Annotator "Sagar Shah"] [PlyCount "47"] {An emphatic victory for Anand. Let's have a look at the game to see what really went right for him and wrong for Svidler.} 1. e4 e5 2. Nf3 Nc6 3. Bb5 a6 4. Ba4 Nf6 5. O-O Be7 6. Re1 b5 7. Bb3 O-O 8. a4 ({The following game between Anand and Svidler with the inclusion of h3 and h6 is very similar to what we saw today.

Because Svidler has got the position 13 times in his games and all the times he has chosen b4.} (8... b4 {is Svidler's move.}) 9. d3 Re8 10. Nbd2 Bf8 11. c3 Na5 12. Bc2 c5 {This is all very standard Ruy Lopez stuff. Now White must remain consistent and break in the centre with d4.} 13. d4 exd4 { This came as a bit of a surprise to Anand. But Peter was mainly trying to play very concrete chess.} 14. cxd4 d5 $6 {Although this is very thematic. It is extremely dangerous. The main reason being that the two bishops on c1 and c2 are opened up against the black king.} (14... cxd4 {looks like the best way for Black to proceed.} 15. e5 Nd5 16. axb5 axb5 17. Nxd4 Nb4 18. Bb1 $13 { is an interesting game.}) 15. e5 Ne4 {This was a critical position where Anand took a lot of time. There are a lot of captures. As Anand correctly pointed out, the main question to him was whether to take on b5 or not. On one hand keeping the a-file closed keeps the rook on the back rank safeguarding it. On the other hand the rook doesn't take part in the game. It is a very difficult decision to make and almost impossible to see what possibilites may arise after say eight to ten moves. But this is where intuition comes into picture and Anand felt that bringing the a1 rook into the game was more important and that explains his next move.} 16. axb5 (16. Nxe4 dxe4 17.

Once you see it, though, and you realize that the bishop on e4 will be a complete monster, breathing fire in both directions, you make this move!} (18. Bxe4 Bxe4 19.

I expected Anand to be looking happy while Svidler would be on the board with his head in his hands. But the scene I saw was completely opposite. Peter had just captured the rook on a8 and was moving around confidently. Anand on the other hand was nervous, fidgety, biting his nails and looked as if he was the one on the back foot. But it was clear that Vishy was calculating the details of his final attack, anxious to make sure that his opponent had no defensive resources. And in the above position he picked up his knight and made the best move 20.Ng5!} 20. Ng5 $1 {Svidler came back and saw this move. I thought that the Russian would think for a while before he would make his move but he blitzed it out. He was showing that he had it under control.} (20. Rh4 Bxf3 21. Bxh7+ Kh8 22. Rh3 Bxd1 23.

It won't be so difficult for a player of Anand's calibre to turn this into a win.}) (21... Bxe4 22. Bxe4 h6 23. Qxf7+ Kh8 24. Qg6 $18) 22. Qxf7+ Kh8 {At this point Peter once again stood up from the board and started walking around. Anand was making his final calculations, the other players were all coming to the board and making faces of disbelief. Nakamura stood right next to Svidler's seat for almost a minute. He just didn't want to leave. He checked the scoresheet, then the board and couldn't believe that Anand was just winning. He went back to his board, Anand lifted his hand and once again made the only winning move in the position.} 23. Rg4 $1 {The rook defends the knight and now the threat is Qg6. Black doesn't really have a way to stop the attack.} (23. Rf4 Ne2+ $19) 23... Qa5 {And once again Anand has the only move to win.} (23... Ne2+ 24. Kf1 $1 {wins!} (24.

The point is subtle. The h3 square has to be kept for the knight to control g1.} (24. h3 Qe1+ 25. Kh2 Ne2 26. Nf3 Bxf3 27. gxf3 Nxd4 $17) (24. h4 Qe1+ 25. Kh2 Ne2 26.
