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.
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
