Almost every other top player  switched to a complex middlegame battle with 4.d3. 9... d8e8  10. b1c3  10... h7h5  11. c1f4  11... f8e7  12. a1d1  12... c8e6  13. f3g5  13... h8h6  14. f1e1  14... e7b4  15. a2a3  15... b4c3  16. b2c3  16... h5h4  17. g2g4  17... h4g3  18. f2g3  18... f5e7 Played after 53 (!!) minutes of reflection.  Nobody really understood what was happening in Grischuk's mind, especially knowing that Vachier-Lagrave had already played like this. Maybe the  Russian GM just forgot about it? "Again, like with Alekseenko, I made a  very stupid thing, thinking for one hour almost about 18...Ne7," he said  afterward. "I was 100 percent, not 99 but 100 percent sure Maxime was  going to play 19.g4 and then he went 19.h4, and, minus one hour. But at  the end maybe it didn't matter too much because anyway I would spend this  one hour somehow!" 19. h3h4 Vachier-Lagrave improves upon his own  game. 19... e7d5 The most aggressive reply, which costed Grischuk another 21  minutes! Yes, there are a ot of things to fear going for a pawn,  especially when your opponent is blitzing his moves after a novelty  delivery. 20. f4c1  20... d5c3
