Nf3 d6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 a6 6. Bg5 e6 7. Qf3 {A rare line, which became popular thanks to the efforts of the unforgettable Bronstein. Recently Nepomniachtchi added it to his repertoire as well.} Be7 ({ The above-mentioned players ended up in identical positions, seprated appart by almost seventy years of chess development and a modest pawn advance (on a3) } 7...

O-O-O Qa5 { Vachier-Lagrave is as always perfectly prepared in his beloved Najdorf.} ({ In the majority of the cases Black prefers to develop his knight on d7, here, or on the next move.

Bc4 $146 {After a heavy thought, Predke decided to switch to Sozin-like development.} ({The predecessor saw:} 10. g4 Nc6 11. Nb3 Qc7 12. Qe2 b5 13. Be3 h5 14. g5 Ng4 15. a3 Rb8 16. Bd2 b4 {with active counter-play for Black, Sedlak,$146 (2524)-Ljubicic,F (2406) Pula 2003}) ({Critical seems} 10. e5 $5 dxe5 {when} 11. Qxb7 $2 {certainly does not work due to} ({However} 11. Nxe6 $1 {leads to interesting complications and unclear play after} fxe6 12. Bxf6 O-O 13. Qxb7 gxf6 14. Rxd7 ({But not} 14. Qxa8 $2 Bc6 15. Qa7 Bc5 { when the queen is suddenly trapped.}) 14... Nxd7 15. Qxd7 Kf7 {and it is anyone's game.}) 11... exd4 12. Qxa8 Qb6 {and Black wins material.}) ({The machine likes Bronstein's} 10. Qg3 $5) 10... Nc6 11. Bb3 h6 ({Another way to play it is} 11... Nxd4 12. Rxd4 Bc6 {but Vachier-Lagrave wants to keep this knight alive for greater deeds.}) 12. Be3 ({Perhaps the computer's} 12. Nxc6 Bxc6 13. Bf4 {is an improvement $2}) 12... Ne5 13. Qe2 ({The queen can be left in front of the pawns with} 13. Qg3 {but from here it does not threaten anything yet, and Black can proceed as in the game} Rc8 14. Qxg7 $2 Rg8 15.

Bd2 (15. bxc3 Nxe4 {is plain bad for White.}) 15... Nd3+ 16. Kb1 Qh5 $1 { and Black is clearly on top.}) 14... b5 15. f4 {Another major decision point. The Russian GM decided to force matters in the center.} ({Th alternative was the doubled-edge position after} 15. a3 b4 16. axb4 Qxb4 17. f3) 15... Neg4 ({ This time} 15... Rxc3 16. Bd2 $1 {does not work for Black.}) 16. e5 ({After} 16. Bg1 b4 $1 {suddenly embarrasses the white knight.}) ({However} 16. a3 { was still possible.}) 16... dxe5 17. fxe5 Nxe5 18. Bxh6 Rxh6 19. Qxe5 {As a result, Vachier-Lagrave won a hefty bishop pair and from here on every endgame he enters would be close (if not perfectly) winning for him. But before that he needs to solve the problem of his king in the middle. Right now Predke threatens various knight jumps, like Nd4-f5, or even Nd4xe6 $1} Qc7 $1 { Very useful $1 The white queen is removed from her optimal position.} 20. Qe2 ( {As we know, the endgame after} 20. Qxc7 $2 Rxc7 {is horrific for White.}) 20...

Qg2 Ra5 {with Black's edge.}) 21. Rh3 ({Here} 21. Rhe1 $1 {looked stronger, when White can consolidate his kingside thank to small tactics, like} Kf8 ({Or} 21... Qxh4 $2 22. Nf5) ({Or} 21... Rxh4 $2 22. Nxe6 $1 fxe6 23. Bxe6 Bxe6 24. Qxe6 Qc7 25. Nd5 $1) 22. g3 {capitalizing on the extra tempo to defend.}) 21... Rc5 $1 {The point behind Vahcier-Lagrave's play. The second rook enters the battle.} (21... Qg4 $5 22. Qe1 b4 {looks good for Black too.}) 22. Re3 Qg4 23. Nf3 Bc6 24. a4 {This turns out to be a weakening.} ({Safer looked} 24. a3 {with the idea to meet} Bxf3 25. gxf3 Qxh4 { with} 26. Bxe6 $3 fxe6 27. Rxe6 Nh5 28. Rxh6 gxh6 29. Qe6 $1 {when the same old machine claims that White has enough initiative for a perpetual.}) 24... Kf8 25. axb5 axb5 26. g3 b4 {Black took full control and now pushes the knight to the edge.} 27. Na2 (27. Na4 Rf5 {is awkward for White.}) 27... Rf5 {The pin is unbearable and Predke goes for a forcing line.} 28. Nd4 Qxe2 29. Rxe2 ({ As we already know the endgame after} 29. Nxe2 Ng4 {is practically unplayable for White.}) 29... Bf3 30. Rxe6 {This was White's point. Alas, there is a drawback.} ({However, the endgames were pretty bad for White as well} 30. Nxf3 Rxf3 31.
