[%c_effect e6;square;e6;type;GreatFind;persistent;true] The dark-squared bishop is lost.
1. e2e4  1... c7c5  2. g1f3  2... d7d6  3. b1c3  3... g8f6  4. d2d4  4... c5d4  5. d1d4 [%cal dd1d4][%c_arrow d1d4;keyPressed;none;from;d1;opacity;0.8;to;d4;persistent;false] Svidler decides to take the game along paths a little less traveled in the Sicilian Defense. The queen capture on d4 has always had its supporters and is a dangerous attempt when used as a surprise. 5... b8c6  6. d4e3 [%c_effect e3;square;e3;type;Interesting;persistent;true] This is a modern idea that Svidler confessed was suggested to him by Praggnanandhaa. The old main line is 6... e7e6 A slightly restricted development that Korobov had already tried before, in a game that must have served as the basis for Svidler's preparation. 6...g6 is more natural. 7. b2b3 [%c_effect b3;square;b3;type;GreatFind;persistent;true] White's plan is to develop the bishop on b2, castle on the queenside, and advance the pawns on the kingside. 7... f8e7  8. c1b2  8... a7a6  9. e1c1  9... d8c7  10. h2h3  10... b7b5  11. g2g4  11... c8b7 The moves for both sides are natural and they are still following Korobov's previous experience. 12. g4g5  12... f6d7  13. c1b1  13... d7c5  14. h1g1 This is an interesting moment of the game. There's a difficult question to be answered: where should the king go, to the queenside or to the kingside $2 14... e8c8 Probably the choice of most humans. 15. f3d4 A natural reaction, but there are alternatives. 15... b5b4  16. c3e2  16... c6a7 [%c_effect a7;square;a7;type;Interesting;persistent;true] An interesting move, with the idea of preserving the knights. Black can try to play with g6 and e5 later, when his knight can go to b5. Of course there are also some weak points to this move, as the knight on d4 is left in a good position. 17. e2g3 [%c_effect g3;square;g3;type;Inaccuracy;persistent;true] Leaving the knight on e2 is more useful, to be able to make the break on c3, opening the queenside. White has three better alternatives. 17... c8b8  18. f2f4  18... h8e8  19. g1g2 [%c_effect g2;square;g2;type;GreatFind;persistent;true] A good move to double rooks on the d-file. 19... e6e5 Korobov decides to take concrete action in the center. He could have waited with some useful moves. 20. d4f5  20... e7f8  21. f4e5  21... d6e5  22. g2d2  22... d8d2  23. d1d2  23... a7b5 [%c_effect b5;square;b5;type;Mistake;persistent;true] A mistake that allows White to disrupt Black's pawn structure on the queenside. 24. f1b5 [%c_effect b5;square;b5;type;GreatFind;persistent;true] 24... a6b5  25. e3e2 White attacks the b5-pawn and also prepares Ne3-d5. 25... f7f6 [%c_effect f6;square;f6;type;Interesting;persistent;true] The alternatives are no better: 26. f5e3 [%c_effect e3;square;e3;type;GreatFind;persistent;true] Even better than capturing the pawn. 26... e8d8  27. e3d5  27... c7d7  28. e2f1 [%c_effect f1;square;f1;type;GreatFind;persistent;true] A strong move, attacking the f6-pawn. The rook can join the attack after going to f2. 28... d7e6  29. g5f6  29... c5e4  30. g3e4  30... d8d5 An important moment: White has several tempting options and it's not easy to choose one. 31. e4g5  31... e6f6  32. d2f2  32... d5d1 [%c_effect d1;square;d1;type;Mistake;persistent;true] This loses by force. 33. f1d1  33... f6f2  34. d1d8  34... b8a7
