The first new move of the game. White should keep the queens on the board.
1. d2d4  1... g8f6  2. c2c4  2... e7e6  3. g1f3  3... d7d5  4. b1c3  4... d5c4  5. e2e4  5... b7b5 [%c_effect b5;square;b5;type;Interesting;persistent;true] This is an interesting and risky variation which is occasionally chosen by strong grandmasters when they want to play for a win with Black. 6. e4e5  6... f6d5  7. c3b5  7... d5b6 Black's pawn structure is weakened, but his pieces gain potential: the d5-square can be used by a knight, and the bishop has a great diagonal on b7. You need to have the right spirit to play like this, offering a long-term advantage in exchange for dynamism. 8. f1e2  8... b8c6  9. c1e3  9... f8e7  10. b5c3  10... c8b7  11. a2a3 [%c_effect a3;square;a3;type;GreatFind;persistent;true] 11... c6a5  12. d1c2  12... d8d7  13. a1d1 A subtle move. White is not in a hurry to castle. 13... f7f5 [%c_effect f5;square;f5;type;GreatFind;persistent;true] 14. e5f6  14... g7f6  15. c3e4 [%c_effect e4;square;e4;type;Inaccuracy;persistent;true] This allows the activation of Black's queen, something that Nepomniachtchi certainly knew from his home preparation. White should play either 15.0-0 or 15.Nd2, with a big open fight in both cases. 15... d7a4 [%c_effect a4;square;a4;type;GreatFind;persistent;true]
