1. d4 Nf6 2. c4 g6 3. f3 {Hari goes for the same move that Magnus Carlsen used
to beat Li Chao at the Qatar Masters 2015.} c5 {This time instead of d5, the
Chinese player goes for c5 which in some ways transposes the game into Benoni/
King's Indian structures.} 4. d5 d6 5. e4 Bg7 6. Ne2 O-O 7. Nec3 $5 {Nec3 was
also used by Anand in his only Classical win against Boris Gelfand in the 2012
World Championship Match.This is how Igor Stohl describes this move. "Rather
unusual, but the underlying idea is sound enough. Instead of bothering to find
a good square for the Ne2, White will rather look for another post for his Nb1
- it might go to a3, or more probably to d2 after Be3(g5).} e5 {This is where
Harikrishna's opening preparation came to an end. This is a pretty rare move.}
8. g4 h5 $5 9. h3 {Looking to cause some major problems with the move Bg5 now.
Li Chao prepares for this.} Nh7 10. Be3 (10. h4 {Hari was looking in this
direction. But after} Bf6 11. gxh5 Bxh4+ 12. Kd2 g5 {He was not so sure about
his position. It looks like after} 13. Kc2 $16 {White should be better.}) (10.
gxh5 $6 Qh4+ $1 11. Kd2 Qxh5 $13) 10... h4 $5 {Black prepares a very
interesting idea of exchanging the dark squared bishops.} 11. Qd2 Bf6 12. Rg1
Bg5 13. Bxg5 Qxg5 (13... Nxg5 {would have been better than the game
continuation.}) 14. Nb5 $1 {This forces Black to retreat with the queen.} Qe7
15. g5 $1 {Blocking the g5 square so that it cannot be used by the black
pieces.} a6 16. N5c3 Nd7 17. Qg2 Kg7 (17... f6 18. gxf6 Rxf6 19. Qg4 g5 20.
Qxh4 Rxf3 21. Nd2 Rf4 22. Qg3 {is quite a messy position but no so bad for
Black.}) 18. Nd2 f6 19. gxf6+ Qxf6 (19... Rxf6 20. Qg4 $16) 20. Nd1 $1 {
A brilliant idea. Black's plan was to play Rf7, Nf8, g5 and Ng6. However, Hari
is quick to take measures against that and prepare Nd1-f2-d3 in order to break
in the centre with f4! This truly shows how strong he is.} Rf7 21. Nf2 Ndf8 22.
Nd3 b5 (22... g5 {was the critical test.} 23. f4 $1 {A similar idea like in
the game.} exf4 24. e5 dxe5 25. Ne4 $44 {With excellent compensation.} Qg6 26.
Qe2 (26. Nxe5 f3 $19) 26... Nd7 27. O-O-O) 23. O-O-O $1 g5 24. f4 $3 {This is
clearly the best move in the game! Black's position is ripped to shreds after
this.} exf4 25. e5 $1 {Pawns are not really so important at this moment!} Qf5 (
25... dxe5 26. Ne4 Qh6 27. Nxe5 Re7 28. Nc6 $16) 26. e6 f3 (26... Re7 27. Qe4
$1 $18) 27. Qh2 Bxe6 {Black sacrifices the piece for a few pawns but it is not
enough.} 28. dxe6 Qxe6 29. Nf2 Qe3 30. Ng4 Qf4 31. Qxf4 Rxf4 32. Nxf3 $1 {
Always tactically alert!} bxc4 (32... Rxf3 33. Bg2 $18) 33. Ngh2 Ne6 34. Rxd6
Nd4 35. Rd7+ Kh8 36. Ne5 Nf8 37. Rf7 Re4 38. Rxg5 Rd8 39. Rxf8+ Rxf8 40. Ng6+
Kg7 41. Nxf8+ Kxf8 42. Rxc5 {A powerpacked game by Harikrishna. Especially the
moves f4 followed by e5.} 1-0
