1. d4 Nf6 2. c4 g6 3. f3 {This Anti-Gruenfeld line is extremely popular
nowadays.} e6 {Diagram [#] A very interesting way to get into another opening.}

-Vachier Lagrave,M (2766) Biel 2014}) 5. d5 d6 6. Nc3 {Now the game transposes
into the Benoni.} ({Bogdanovich played instead} 6. Ne2 {against Nepomniachtchi
but failed to impress with opening advantage} Bg7 7. Nec3 Nh5 8. Be3 exd5 9.
cxd5 f5 10. Bb5+ Nd7 11. exf5 gxf5 12. f4 Nhf6 $1 13. O-O Ng4 {and Black was
happy in Bogdanovich,S (2581)-Nepomniachtchi,I (2714) Moscow 2015}) 6... Bg7 7.
Nge2 exd5 8. cxd5 O-O 9. Ng3 a6 {Diagram [#]} ({I have the feeling that the
immediate} 9... h5 {is more accurate. But that is a matter of taste.}) 10. a4
h5 11. Be2 {Most commonly White prefers the move 11.Bg5 in this situation.} ({
One more recent example in this line goes} 11. Bg5 {seems unpleasant for Black,
but he can easily get rid of the bishop, with a tempo} Qc7 12. Be2 Nh7 13. Be3

Diagram [#] Nepomniachtchi played this novelty in a flash. The queen moves
away from the possible pin on g5.} ({Practically all previous games continued}
11... h4 {Right now, before the knight gets the h1 square! The knight on f1 is
somewhat misplaced while from h1 it easily gets to f2 to overprotect the e4
pawn. One example} 12. Nf1 Nbd7 13. Bg5 h3 14. gxh3 Rb8 15. Ng3 Qb6 {with
counterplay for Black in Ivanchuk,V (2733)-Bacrot,E (2730) Cap d'Agde 2013})
12. Bf4 $1 {So wants to prove that the queen sortie was premature.} ({A
natural reply would be} 12. O-O h4 13. Nh1 Nh5 14. Nf2 {with somewhat better
position for White.}) ({Black's idea is revealed in the line} 12. Bg5 Nh7 13.
Bf4 (13. Be3 f5) 13... h4 14. Nf1 Qe7 {followed by f7-f5 and possibly g6-g5.})
12... Qe7 13. Bg5 Qe8 {Black lost a couple of tempoes, but he intends to take
back one of them with the mauver Nf6-h7. Creativeness is a good thing, but
tempoes are tempoes.} (13... Nbd7 14. Qd2 {is not what Black was hoping for.})
14. Qd2 Nbd7 15. Bh6 $6 {Possibly a bit premature. White had good alternatives
in his disposal. Both} (15. a5 $5) ({and} 15. O-O $5 {lead to slight advantage
to White.}) 15... Qe5 $1 16. Bxg7 Kxg7 17. Bd3 $6 {So frees the e2 square for
the g3 knight and prevents the unpleasant check on d4. Still, this looks
rather slow.} ({In case of} 17. O-O Qd4+ $1 {[%csl Yc3] Diagram [#]} 18. Qxd4
cxd4 19. Na2 h4 {Black has no problems whatsoever.}) ({Thus} 17. Nf1 {although
as said before the knight is not extremely happy on f2.}) 17... Rb8 {Prepares
the standard b7-b5 break.} (17... h4 18. Nge2 {is also OK for Black.}) 18. Rd1

Nepomniachtchi can be happy with his opening idea. He had equalized at least.}

huge complications.}) 24... cxb3 {with counterplay.}) 24. Na4 {If anything,
White will get some time to finish his development.} Ra8 25. b3 Ba6 {And Black
is also happy to trade his light-squared bishop. All in all the position
remains balanced.} 26. Bxa6 Rxa6 27. O-O {[%cal Ge1g1] Diagram [#] White

look for a way to get counter-play on the other wing.} Rea8 28. f4 Qe7 $6 {The
first inaccuracy by Black in this game.} ({Strong was to get into an endgame
