1. d2d4  1... g8f6  2. c2c4  2... e7e6  3. b1c3  3... f8b4  4. e2e3  4... e8g8  5. c1d2 A fashionable variation in the Nimzo-Indian. You can check my analysis of Nakamura-Praggnanandhaa from the same tournament. 5... b7b6  6. f1d3  6... c8b7  7. g1e2 [%c_effect e2;square;e2;type;Interesting;persistent;true] The development of the knight on e2 in this line is somewhat surprising. 7... d7d5  8. c4d5  8... e6d5  9. e1g1  9... f8e8  10. a1c1 The game has transposed to a position that has been played by strong grandmasters a few times. 10... a7a6 A good move in order to play ...Bd6 without having to worry about Nb5. 11. f2f3  11... b4d6  12. g2g4 The advance of the pawns on the kingside is one of White's plans in this pawn structure. 12... h7h6 Understandably, Black wants to avoid the g4-g5 advance, but with the pawn on h6, White gains a target. 13. d1e1 The typical queen maneuver, but there's another interesting plan. 13... c7c5  14. e1h4 The queen will soon return from this square, so consideration must be given to the alternatives 14.Qf2 or even the immediate 12.h4. 14... b8d7 [%c_arrow b8c6;keyPressed;none;from;b8;opacity;0.8;to;c6;persistent;false,b8d7;keyPressed;none;from;b8;opacity;0.8;to;d7;persistent;false] I always find it a bit difficult to decide where to develop this knight in similar pawn structures, to c6 or d7. 15. h4f2 [%c_effect f2;square;f2;type;Inaccuracy;persistent;true] It's curious that the queen goes to h4 and then returns to f2. 15... d7f8 [%c_arrow f8e6;keyPressed;none;from;f8;opacity;0.8;to;e6;persistent;false] The knight is going to the solid square on e6, but there's an alternative route: 16. h2h4 [%c_effect h4;square;h4;type;GreatFind;persistent;true] White keeps pushing the pawns, a dangerous plan. 16... f8e6  17. g1h1 [%c_arrow b7h1;keyPressed;none;from;b7;opacity;0.8;to;h1;persistent;false] The king doesn't feel very secure on the bishop's diagonal. 17... b6b5 Black's position is clearly good, but it's never easy to play when you're under a possible attack. 18. a2a3  18... f6d7 A subtle move, maybe even too subtle. There are good alternatives. 19. f1g1  19... d7f8 Playing safe. 20. f3f4 Ju goes all-in  $1 20... c5d4  21. e3d4  21... e6c5 [%c_effect c5;square;c5;type;GreatFind;persistent;true] An excellent reaction. As I mentioned, the king on h1 does not feel safe on this diagonal. 22. d3c2 [%c_effect c2;square;c2;type;GreatFind;persistent;true] 22... c5e4  23. c3e4  23... d5e4  24. d2e3 The e4-pawn has to be blocked. 24... a8c8  25. f4f5
