1. e2e4  1... e7e5  2. g1f3  2... b8c6  3. f1c4  3... f8c5  4. c2c3  4... g8f6  5. d2d3  5... d7d6  6. c1g5  6... h7h6  7. g5h4  7... d8e7 A rare move that certainly caught Nepomniachtchi by surprise, since in just two moves his position becomes much inferior. The plans with a quick g7-g5 are more common. 8. b2b4 The beginning of a wrong plan. 8... c5b6  9. a2a4 Normally White continues like this after playing b2-b4, but in this position it leads to problems. 9... a7a5  10. b4b5  10... c6d8 The knight is ready to go to e6 and then f4 when Black can then play g7-g5 strengthening its position. Still, it's surprising that the computer already considers Black's position to be much better. Because Black can still castle on the queenside, things are worse for White, since with the inclusion of a5-b5, this flank is closed and Black has a free pass for an attack on the kingside. 11. b1d2  11... d8e6  12. e1g1  12... e6f4  13. d3d4  13... c8g4  14. d1b3  14... e8c8 Black's king is very safe on this side of the board. 15. f1e1  15... g7g5  16. h4g3  16... g4h5 A useful move to prepare g5-g4 or get the bishop to g6. 17. c4f1  17... c8b8 This move is always useful. 18. a1d1
