The minute spent on the clock best describes the shock that the Russian GM experienced.
1. g1f3  1... g8f6  2. g2g3  2... d7d5  3. f1g2  3... c7c5  4. e1g1  4... g7g6  5. d2d4  5... c5d4  6. f3d4  6... f8g7  7. d4b3  7... e8g8  8. b1c3  8... e7e6  9. e2e4 An interesting Anti-Grunfeld line that Ding had used successfully in the past. He is in fact playing the Grunfeld himself now, with reversed colors, and an extra tempo. 9... b8c6  10. e4d5  10... f6d5 Since Black is getting an isolani, it makes sense to preserve more pieces on board, but Grischuk has a concrete idea on his mind. 11. c3d5  11... e6d5  12. c2c3  12... d5d4 That is the point. Black quickly gets rid of the isolated pawn. But not from all the problems. 13. c3d4 More or less forced. 13... c6d4  14. c1e3 [#] 14... d4c6 Up to here all has been seen in an email game. Only this move is a novelty. Grischuk blocks the enemy bishop and intends to develop his own light-squared one. 15. b3c5 Highlighting Black's main problem. How to develop the queenside $2 15... d8e7  16. f1e1 [%c_effect e1;square;e1;type;GreatFind;persistent;true] X-raying her majesty is three times more unpleasant in a blitz game than in a normal one. 16... f8d8  17. d1b3  17... e7c7  18. a1c1 The poor queen cannot find a safe square. 18... c7b6 The most natural move is a blunder. 19. c5b7 [%c_effect b7;square;b7;type;GreatFind;persistent;true] The winning combination. 19... b6b3  20. b7d8 [%c_effect d8;square;d8;type;Brilliant;persistent;true] A star move $1 Many GMs would have been proud of finding it in a normal game. Ding spent a couple of seconds on it $1
