1. g1f3  1... d7d5  2. e2e3  2... g8f6  3. c2c4  3... c7c5  4. c4d5  4... f6d5  5. b1c3  5... b8c6  6. f1b5 This line is coming into the spotlight lately. White is playing in the spirit of the Four Knights Sicilian. 6... d5b4 Not the strongest option in the Sicilian, but perhaps it will work here $2 7. a2a3  7... b4d3  8. e1e2  8... d3c1  9. a1c1 Black won the bishop pair but at the price of a serious development deficit. 9... c8d7  10. d2d4 Certainly $1 Harika wants to open up the position with her better prepared pieces. 10... c5d4 All of this has been seen before, and Black did well in the predecessor. Kosteniuk was, however, out of luck today. 11. b5c6 [%c_effect c6;square;c6;type;GreatFind;persistent;true] A strong novelty, which practically wins material by force. The bishop pair would not last for long; neither will Black's queenside. 11... d7c6  12. f3d4  12... d8b6 Kosteniuk is desperately trying to cement her queenside. 13. d4c6 There goes the bishop pair. 13... b7c6  14. d1a4 [%cal Rc3d5] With the huge threat of Nc3-d5 $1 14... a8d8 [%c_effect d8;square;d8;type;GreatFind;persistent;true] A smart way to defend, but White is too far ahead in the development. 15. b2b4 [%c_effect b4;square;b4;type;GreatFind;persistent;true] One of the good moves. 15... e7e6  16. c3e4 The c6-pawn is doomed. Kosteniuk needs to safeguard her king first, and this takes too much time. 16... d8c8  17. e4d2 The knight is aiming against the pawn. 17... a7a6  18. d2c4  18... b6b5  19. a4b5  19... a6b5  20. c4e5 This is it; the pawn is gone.
