1. e2e4  1... c7c5  2. g1f3  2... e7e6  3. d2d4  3... c5d4  4. f3d4  4... g8f6  5. b1c3  5... d7d6 The Scheveningen Variation is not a regular guest in elite tournaments these days, mainly because of the Keres Attack, which we see in the game. 6. g2g4 [%c_effect g4;square;g4;type;GreatFind;persistent;true] Clearly the most uncomfortable move for Black. White does not need to ask for permission to make this move, as is often the case against Najdorf, for example. 6... h7h6  7. h1g1 White has other promising options. 7... b8c6  8. c1e3  8... f8e7 A critical position. Karpov had great games against the Scheveningen and three of them in this position. 9. d1d2  9... c6d4  10. d2d4  10... e6e5 [%c_effect e5;square;e5;type;Interesting;persistent;true] Black changes the character of the game. 11. d4a4  11... e8f8  12. f2f3 With Black's uncastled king in a typical English Attack position, White has to have the upper hand. But things are never easy in the Sicilian. 12... a7a6  13. e1c1  13... c8e6  14. c3d5  14... b7b5 Only this move is new. 15. a4b4  15... e6d5  16. e4d5  16... f6d7 Black's dream is to play Bg5 and exchange bishops, but White avoids this with her next move. 17. h2h4 [%c_effect h4;square;h4;type;GreatFind;persistent;true] 17... d8c7  18. d1d2 [%c_effect d2;square;d2;type;Mistake;persistent;true] With this move, White loses all the advantage. There's no need to surrender the h-pawn. 18... e7h4 [%c_effect h4;square;h4;type;GreatFind;persistent;true] 19. d2h2  19... g7g5 [%c_effect g5;square;g5;type;GreatFind;persistent;true] A difficult move to play, but now White can no longer advance the dangerous g-pawn. 20. f3f4 [%c_effect f4;square;f4;type;Mistake;persistent;true] A mistake never comes alone... 20... a8c8 [%c_effect c8;square;c8;type;Mistake;persistent;true] Black should immediately follow the plan that she will carry out later in the game. 21. f1d3 [%c_effect d3;square;d3;type;Mistake;persistent;true] 21... e5f4 [%c_effect f4;square;f4;type;GreatFind;persistent;true] 22. e3f4  22... g5f4  23. h2h4  23... d7e5 Considering what happened in the opening, this position seems like a sweet dream for Black. The knight on e5 is such a strong piece in this pawn structure. 24. b4e4  24... c7c5  25. g1h1  25... c8e8  26. h4h3  26... f4f3 [%c_effect f3;square;f3;type;GreatFind;persistent;true] 27. h1f1  27... h8g8 [%c_effect g8;square;g8;type;GreatFind;persistent;true] 28. e4h7  28... c5e3  29. c1d1  29... h6h5 [%c_effect h5;square;h5;type;Inaccuracy;persistent;true] Tan was in severe time trouble and plays a pretty move that objectively is not the best. 30. g4g5 [%c_effect g5;square;g5;type;Inaccuracy;persistent;true] 30... e5d3  31. h7d3  31... e3e2  32. d1c1  32... e2d3  33. c2d3  33... g8g5  34. h3f3  34... e8e7 The d5-pawn will fall. The endgame is winning. 35. c1d2  35... g5d5  36. f1c1  36... e7e5  37. c1c7  37... e5f5  38. f3f5  38... d5f5  39. c7c6  39... h5h4
