1. e2e4  1... c7c5  2. g1f3  2... d7d6  3. b1c3  3... g8f6  4. h2h3 According to my database, this is only the second time Vachier-Lagrave plays this system. It's interesting to see him avoiding a theoretical battle in his favorite Najdorf Defense. 4... a7a6 Black has many ways of playing, but including a6-a4 is useful to discourage White's plans of castling queenside in the future. 5. a2a4 Played in order to prevent b7-b5. 5... b8c6  6. d2d4  6... c5d4  7. f3d4  7... c8d7 Nepomniachtchi had played this move before. My impression is that he wants to prevent the plans with the exchange of the knight on c6 followed by a4-a5. 8. c1e3  8... e7e6  9. f1e2  9... f8e7  10. e1g1  10... e8g8 Now we have on the board a version of the Scheveningen Defense, which Kasparov liked so much, but a slightly improved one for Black, since White's pawn on h3 is not very useful. Normally this position is reached with the pawn on f4 instead of the pawn on h3. 11. f1e1 A difficult move, since this is not the classical way of playing this pawn structure. 11... a8c8  12. d4c6  12... d7c6  13. e2d3  13... f6d7 The opening was a success for Black, who has no problems whatsoever. But White retains a space advantage and the position remains balanced. 14. a4a5  14... e7f6  15. d1d2  15... d7c5  16. f2f3 A somewhat sad move, but necessary to defend the e4-pawn. 16... c5d3  17. c2d3  17... d6d5 Nepomniachtchi tries to open the game for the bishops. 18. e3b6  18... d8d6 The best square for the queen, otherwise White closes the game with e4-e5. 19. d3d4  19... d5e4  20. f3e4  20... d6d7  21. e1f1
