[Event "FIDE WWCC 2017"] [Site "Tehran"] [Date "2017.02.23"] [Round "5.1"] [White "Tan, Zhongyi"] [Black "Harika, Dronavalli"] [Result "1-0"] [ECO "E54"] [WhiteElo "2502"] [BlackElo "2539"] [Annotator "Swati Ghate"] [PlyCount "87"] [EventDate "2017.??.??"] [SourceDate "2003.06.08"] {First game of Semi Final Match between players from two Asian power houses in chess. Only one player from India or China will go into the finals which I think will be a history in the World championship. Tan Zhongyi looks in good form as she crushed comfortably talented and second highest rated player Ju Wenjun in Quarter final. Harika also won convincingly with white in classical game but had to go to rapid games to cruise into the semi-finals.} 1. d4 e6 2. c4 Nf6 {Harika shows good preparation going into various new set ups. Normally she employs this mostly against Nf3 set ups.} 3. Nc3 Bb4 4. e3 O-O (4... b6 { is also played here.}) 5. Bd3 c5 6. Nf3 d5 7. O-O cxd4 8. exd4 dxc4 9. Bxc4 b6 {Both the players are going for main lines without fearing home preparation. Black tries to play on white squares and three pawn islands whereas white gets double bishops, center, and activity.} 10. Bg5 Bb7 11. Qe2 Bxc3 12. bxc3 Nbd7 13. Bd3 Qc7 14. Rac1 Ng4 15.
