1. d2d4  1... g8f6  2. c2c4  2... g7g6  3. h2h4 In a must-win situation Vachier-Lagrave should  be creative. 3... f8g7  4. b1c3  4... d7d5  5. h4h5  5... f6h5  6. c4d5  6... e7e6  7. g2g4 An original and  strong idea. 7... h5f6  8. d5e6  8... c8e6  9. e2e4  9... e6g4  10. f2f3  10... g4e6  11. c1g5 Forcing a kingside weakness thanks to the e4-e5  threat. As a result of Benko-style play on the kingside, Vachier-Lagrave  got a super-strong center for the pawn and a space advantage. Black's main problem now will be where to hide his king. 11... h7h6  12. g5e3  12... c7c6  13. g1e2  13... e6c4 Nepomniachtchi is happy to trade some light pieces. He should  not delay this move as otherwise Ne2-f4 would be highly unpleasant.
