The Indian grandmaster was the first to win a game in the elite Shenzhen Masters.

Pentala Harikrishna of India leads the elite Shenzhen Masters tournament in China after winning his second round over Michael Adams of England. It was the first decisive result of the double round-robin tournament; which includes six of the world’s top 20 players.

Adams, who had White, got some slight pressure in a Catalan opening, but he never really had serious winning chances. He then mishandled the position as his clock ran down towards the end of the first time control.

Shenzhen Masters | China | Round 2 | 24 Mar 2017 | 0-1
24. Bxd5 White is slightly better in this position because of his strong bishop and more mobile pawn majority, but it's not that much of an advantage and it is important not to over press. Adams started off well enough.
24... Rcd8 25. Bc4 Nc6 26. f4 Rxd1 27. Rxd1 Rd8 28. Rd5 Rxd5 29. Bxd5 Nb4 30. Bb3 The trade of all the rooks has been fine for White. Now he could try a slow invasion with his king, using the light squares to good effect. But the key word is slowly!
30... Nc6 31. Kf2
31. Bc4 I would prefer a patient move like this one. The goal should be to play e6.
31... Qd7 32. Kg2 White can push for a long time, and Black would be best advised to avoid a trade of queens.  )
31... Qd7 32. Qc4?! White is starting to lose the thread. He has a lot of pressure on f7 but is abandoning the kingside.
32... Nd4 33. Ba2? This is a mistake.
33. Qd5! This move was necessary.
33... Qf5 34. e6 Qxd5 35. Bxd5 fxe6 36. Bxb7 White can push a bit in this position, but Black should be able to hold a draw.  )
33... b6 34. Ke3? Adams was getting low on time at this point. He deserves credit for playing for a win, but he was rapidly losing control of the position.
34... g5! Now White's king is starting to feel some heat. Black threatens gxf4 followed by Qh3.
35. fxg5 hxg5 36. Qf1?
36. Qd5! This was the last chance. After
36... Qf5 37. Bc4! White has nothing better than a draw, though this is very hard to see in time pressure.  )
36... Nc6! The pawn on e5 will be lost. White lost a piece on the next move but Black was winning anyway.
37. Qd3 Qxd3+ 38. Kxd3 Nb4+ And Harikrishna went on to win easily.

Anish Giri of the Netherlands has played so far. After achieving an easy draw with Black in Round 1, he got a nice position from his preparation against Ding Liren of China in Round 2. But a couple inaccuracies and good defense from Ding led to a draw.

18. h3 Giri showed some nice preparation in this game, but he only obtained a tiny edge and Ding was able to buckle down and gradually equalize.
18... Rxd3! Forcing exchanges.
19. Qxd3 Bc4 20. Qd2 Bxf1 21. Rxf1 Re8 Black is hoping that the semi-open e-file and targeting the White e-pawn will be as useful as the open d-file is for White.
22. Rd1 Qb4 23. a3 Qc4 24. Qd4 Qxd4 25. Rxd4 White has a slight edge in the ending, but Ding has a plan.
25... Re7! This looks like a very good way to meet the threat of e5.
25... Kf8? 26. e5 And White can invade.  )
26. e5 Nd7! Now White has the only open file, but Black is planning to play f6 and then he will also have an open file on which to operate.
27. g3 Kf8!
27... f6? Not yet...
28. e6  )
28. Kg2 Nc5! Again eschewing f6 until e6 cannot be played in reply.
29. Kf3 f6! Now it's time. White is still a little better but now he faltered.
30. Rd8+?!
30. exf6! gxf6 31. Rd6 And White would have still had some winning chances.  )
30... Kf7 31. Ne4 Nxe4 32. Kxe4 This position looks very promising for White with his active king and passed e-pawn, but Ding was ready and showed the route to a draw:
32... fxe5! 33. fxe5 Re8! 34. Rd7+ Re7 Giri decides to accept a draw through repetition of the position rather than retreat his rook.
35. Rd8 Re8

The other game, between Peter Svidler of Russia and Yu Yangyi of Chhina, was very level throughout.

10. Ne2 This position looks like it arose from the Italian opening, but it is somewhat unusual. Normally, White would have played c3 by now, and the knight would be on d2 instead of e2. The differences pose no problems for Black, who is able to equalize easily by forcing exchanges.
10... Be6! 11. Bxe6 fxe6 Normally, White's queen would move to b3, but in this position that is not possible.
12. Ng3 O-O 13. c3 Qe8 14. O-O Nh5! Forcing more exchanges.
15. Nxh5 Qxh5 16. Be3 Bxe3 17. fxe3 Rf6 18. Ra2 Raf8 19. Raf2 With a symmetrical structure, identical pieces on both sides, and equal activity among those pieces, peace is all but assured.
19... Nd8 20. Qa4 Qg6 21. Kh2 Qf7 22. Kg1 Qg6 23. Kh2 Qf7

Given how strong the field is, full points are going to be hard to come by, so winning with Black has given Harikrishna a big leg up.
