[Event "chess.com IoM Masters"] [Site "Douglas ENG"] [Date "2016.10.07"] [Round "7.13"] [White "Harika, Dronavalli"] [Black "Hou, Yifan"] [Result "1-0"] [ECO "A10"] [WhiteElo "2528"] [BlackElo "2649"] [Annotator "Sagar Shah"] [PlyCount "89"] [EventDate "2016.10.01"] {Harika and Hou Yifan have played 22 times against each other in the last 10 years. The Chinese grandmaster has won five times and rest 17 games have ended in draws. This was the first time that Harika managed to outwit the reigning World Champion.} 1. c4 b6 $5 {Hou Yifan tries to mix it up out of the opening.} 2. Nc3 Bb7 3. e4 c5 4. Nge2 Nf6 5. d3 d6 6. g3 g6 7. Bg2 Bg7 8. O-O {The Botvinnik setup chosen by Harika is one of the easiest way for White to play. It can be used against many openings and hence a knowledge of it can be highly useful. Whatever Black does, White's setup remains the same. The pawns are on c4-d3-e4 and g3, the knights stand on c3 and e2 and the bishop goes to g2. After this the plans vary. Sometimes White can go for Be3-Qd2 and Bh6. Sometimes Rb1 followed by queenside expansion with a3-b4, and as Harika played in the game - f4-g4 with a kingside attack. The system is highly flexible and quite easy to understand.} Nc6 9. h3 {Stopping Ng4 and getting ready to play Be3.} O-O 10. Be3 Rc8 11. Qd2 {d4 is not yet possible because the c4 pawn would be hanging.} Re8 12. b3 Nd7 13. Rac1 (13. d4 {This was definitely possible.} cxd4 14. Nxd4 Nxd4 15. Bxd4 Bxd4 16. Qxd4 Qc7 17. Rac1 $14 { According to me White has the slightly preferable position thanks to her space advantage, but the position is simplified and hence easier for Black to play. It is interesting to note that Harika didn't go for this. Maybe she wanted to keep the position more complicated and fight for the full point.}) 13... a6 14. f4 $5 {And there we go! White starts the kingside offensive.} Nd4 15. g4 e6 16. Ng3 Rc7 17. g5 b5 {Overall Black's position looks very cohesive. White cannot easily play f5 as then the knight on d7 is waiting to jump into e5. Meanwhile it is not so clear What Harika must do.} 18. Rce1 b4 19. Nce2 Nxe2+ 20. Rxe2 Nb8 21. d4 $5 cxd4 22. Bxd4 Bxd4+ 23. Qxd4 e5 {Hou Yifan gets the e5 square for her knight with this move, but in return the f-file is opened up for the white pieces and the d6 pawn is weakened. The position should be round about equal.} 24. Qd2 exf4 25. Qxf4 Nc6 26. Rd2 Ne5 27. Rfd1 {Both sides have their own trumps, but it seems that the knight on e5 is not as dangerous as it looks and the d6 pawn weakness definitely counts for something more.} Rd7 28. h4 { Bh3 is a big threat now.} Qe7 29. Nh1 $5 {A Nimzovian idea! The knight will go from f2-d3 in order to evict the one on e5.} (29. Bh3 Rdd8 30. Kg2 $1 { Threatening c5 which is not so easy to meet.} (30. c5 d5 31. exd5 Qxc5+ $17)) 29... Kg7 30. Rf1 Red8 31. Qf6+ $5 Qxf6 32. gxf6+ Kf8 {The pawn on f6 is a thorn in Black's position and Harika quite correctly realized that when she went for the queen exchange.} 33. Rfd1 Rc7 34. Nf2 Ke8 35. Kh2 Rc6 36. Kg3 Kd7 37. Nd3 $1 Ke6 $2 (37... Nxd3 38. Rxd3 Re8 39. e5 $1 $18) 38. Nxe5 Kxe5 39. Rd5+ Kxf6 40. e5+ Ke6 41. c5 (41. R5d2 Rb6 42. c5 $18 {was the fastest way to win.}) 41... f5 42. exd6 {Out of nowhere Harika has two amazingly strong passers and they are on dark squares which means that the bishop can remove the blockaders!} Rd7 43. Re1+ Kf6 44. Rde5 Rc8 45. Re6+ {Hou Yifan rightly resigned as Re7 comes next and Harika would win an entire piece and her two strong pawns would still remain. A very interesting battle and great fighting chess showcased by the Indian.} 1-0

Everything is in place so let's get going!} Nh5 17. c5 $1 { Amazing move. White wants to destroy the d6 pawn so that he can either play f4-f5 or open the f-file for his rooks. And the other interesting point to note is that Harika too beat Hou Yifan with her pawns on e5 and c5!} (17. f5 dxe5 {is better for White but not as much as in the game.}) 17... d5 (17... dxc5 18. f5 $1 $18) (17... dxe5 18. fxe5 Bg7 19.

Sergei Tiviakov in his video on CBM 168 mentions that if White wants to fight for an advantage he must refrain from the move 8.e4 and instead go for castling. As things went in this game, we cannot really argue with what Tiviakov says.} d5 9. exd5 cxd5 10. Ne5 O-O 11. O-O Nc6 12. cxd5 Nxe5 $1 { Of course the line that Black is walking is quite narrow. He has to make all the accurate moves in order to equalize. But you can be rest assured that a player of Eljanov's calibre has it all worked out at home.} 13. d6 Nc6 14. dxe7 Qxe7 15. Bg5 h6 16. d5 Na5 17. d6 {This is the first move where the game deviates from the Anand-Carlsen World Championship Match. Vishy had taken on f6. Vidit comes up with this natural move, but now it is open for debate whether the pawn on d6 is a strength or a weakness.} (17. Bxf6 Qxf6 18. dxe6 Bxg2 $1 19. exf7+ Qxf7 20. Kxg2 Nc4 21.

R4d2 Na5 {Vidit could have settled for a draw here with Rd4 but instead he went for something more ambitious. Not that the position warrants it, but his age definitely does!} 25. g4 $5 {I would say after this move, all three results are possible. White tries to play acctively but at the sam time weakens his own king. Objectively this is not a great move.} Rfd8 26. Ne4 Nc4 27. Rc2 Ne5 28. Rdc1 Rxc2 29. Rxc2 Qb7 30. f3 Qd5 31. Rd2 Qc4 32.
