1. Nf3 {Navara plays pretty much everything and varies his openings on accaunt
of the opponent. In this game he chose a tricky opening idea to deal with the
Gruenfeld defense.} Nf6 2. c4 c5 3. Nc3 d5 4. cxd5 Nxd5 5. e3 {In search of
innovation! This line is quite fresh and fashionable. White is mainly pinning
his hopes for an opening advantage with one of the following continuations:} (
5. g3) (5. d4) (5. e4) 5... Nxc3 {This was perhaps easy to predict.} ({Peter
Leko's careful aproach led to a completely different game after} 5... e6 6. d4
cxd4 7. exd4 Be7 {with a typical IQP position that arises from the Panov/
Nimtzo-Indian/Tarrasch openings, Tomashevsky,E (2714)-Leko,P (2731) Sochi
2014. The problem with this aproach however is that Nepomniachtchi does not
play neither of these openings, at least with the black pieces. He is an
expert of the Panov attack, but as White.}) 6. bxc3 Qc7 7. Bb2 $1 $146 {[%csl
Rg7][%cal Rb2g7,Gc3c4] Diagram [#] A novelty on move seven! It seems illogical
to place the bishop on the diagonal which is blocked by the pawn, but this is
only temporary. The world champion had tested} (7. d4 g6 8. Bb5+ Bd7 9. a4 Bg7
10. O-O O-O 11. Ba3 b6 {when the position still resembles the Gruenfeld,
Carlsen,M (2881)-Giri,A (2752) Stavanger 2014}) 7... Nd7 ({If anything, Black
is not going to fianchettoe the bishop!} 7... g6 $6 8. c4 {is awkward for the
second player.}) ({Perhaps Black will try in the future} 7... e5 {with natural
development- Bf8-e7, Nb8-c6 and central control.}) 8. Qb3 e6 ({Once more the
fianchettoe is not appealing} 8... g6 9. Ng5 e6 10. c4 e5 {when White has a
pleasant choice between the aggressive} 11. h4 ({and} 11. f4) ({or the
positional} 11. Be2 {after which the knight on g5 will be rerouted to the d5
square via e4-c3.})) 9. c4 {The opening operation was successful! Navara took
his opponent out of the book and objectively speaking White enjoys some
pressure. The bishop on b2 is very nicely placed.} b6 10. a4 {Since the black
kingside is frozen, White prepares a "warm" welcome for the black monarch.} Bb7
({The careless} 10... e5 $6 11. a5 Bb7 $2 {allows a nice combination} 12. axb6
axb6 13. Rxa8+ Bxa8 {[%csl Ya8,Ye8] Diagram [#]} 14. Nxe5 $1 Nxe5 15. Bxe5 Qxe5

diagonal and free his bishop.} ({Things are not very optimistic for Black after
} 11... O-O-O 12. axb6 (12. Be2) (12. Bd3) 12... axb6 13. Be2) (11... e5 $2 {

became vulnerable and the Czech Grandmaster neatly uses that.} Bd6 $6 {An
inaccuracy.} ({Better was} 12... Be7 $5 {with the idea} 13. Qc2 f5 14. Bxg7 Rg8

advantage} ({Or the more entertaining} 15. Nxe6 $5 Kxe6 16. Bxf5+ Kf7 17. Bxh7)

work.}) 19... Qxf7 (19... Kxf7 20. Rxg7+) (19... Rg8 20. Nh6 Rh8 21. Bxg7) 20.

anywhere...} O-O-O {Nepomniachtchi decided this is the lesser evil. However...}

by Rh3-g3 and h4-h5. You did not forget about the bishop on b2, did you?}) 18.

concentration in the attack is enviable!} ({Both} 25. Qg4) ({and} 25. Qg6 {
were tempting but the text is stronger.}) 25... Bc7 26. Rba2 {White's position
is overwhelming. The rooks are about to enter the king's castle.} Bb8 27. Ra8

co-operate much better with the knight than the black rooks and the bishop.} (
