An interesting novelty. White offers a pawn because he would really love to enter on the seventh with his rook. 16.Rfc1 Rac8 17.Ba6 Nf6 18.Bxb7 Qxb7 19.e5 Nd5 20.Rc4 cxd4 21.Nxd4?! 21.Qd2 Rxc4 22.Rxc4 Qa6 23.b3 b5 24.Rxd4 Rc8 21...Nf4 22.Qf1 Rxc4 23.Rxc4 Qe4 24.b3 Qxe5 Cvek,R (2440)-Jaworski,M (2400) Tschechien 1999 16...Rac8 16...cxb4? does not work: 17.Rc7 Rab8 18.Ne5 Rfd8 19.Bb5 Qd6 20.Rxd7 Rxd7 21.Nxd7± But 16...cxd4 is possible because after 17.Rc7 Rab8 18.Ne5 Rfd8 19.Bb5? 19.f4= 19...Qd6 is better for Black. 17.dxc5 bxc5 18.b5 c4 Forcing events. 18...Nb6 or 18...Rfd8 were quieter alternatives. 19.Rxc4 Rxc4 20.Bxc4 Qb4 21.Rd1 Rc8 Black is active enough to regain the pawn. 22.Rxd7 22.Nd2 Nc5 23.Rb1 Qc3 24.f3 Na4 25.Bb3 Qc5+ 26.Qf2 Nc3 27.Qxc5 Rxc5 28.Rb2 Nxb5= 22...Rxc4 23.h4 Qxb5 24.Rd8+ Kh7 25.Kh2 Rb4 26.Qxb5 Rxb5 27.Nd4 Rb4 28.f3 Kg6 The position is equal but the grandmasters continue to fight. 29.Nb3 Bc6 30.Rc8 Bb5 31.Rc7 Ra4 32.h5+ Kf6 33.e5+ Kf5 33...Kxe5?? 34.Rc5++- 34.Kg3 g5 34...Rxa2?? 35.Nd4++- 35.Nc1 a5?! Black should have attacked the white weaknesses. 35...Bf1! 36.Rxf7+ Kxe5 37.Kf2 Bc4 38.Rh7 Rb4 39.Rxh6 Rb2+ 40.Ke3 40.Kg3? Bf1-+ 40...Rxg2 should lead to a draw. 36.Rxf7+ Kxe5 37.Rh7 Rh4 38.Rxh6 a4 That was Ivanchuk's idea. He wants to catch the knight on b1. 39.a3! Putting the pawn on a black square where it is safe from Black's bishop. 39.Rh8 Rh1 40.Rb8 Bc4 41.h6 Kf6!= 39...Bc4 40.Kf2 40.Rh8 was the alternative: Kf6 40...Rh1 41.h6! Kf6 41...Rxc1 42.Rc8! Rh1 43.Rxc4 Rxh6 44.Rxa4+- 42.h7 Kg7 43.Rc8 Bb5 44.h8Q+ Rxh8 45.Rxh8 Kxh8 46.Kg4 Bf1 47.g3± 41.Rh7!? Rh1 42.Rc7 Bd5 43.Nd3 Rxh5 44.Ra7 Rh4 45.Nc5 Rc4 46.Nxa4 40...Rh1 41.Ne2 Ra1? Black had to put his hopes on the rook ending that arises after 41...Bxe2! 42.Kxe2 Ra1 It seems as if his counterplay is just in time. 42.Rg6! Bd3 42...Bxe2 now fails to the "zwischenzug" 43.Rxg5+± 43.Rxg5+ Kf6 44.f4 44.Rg8 might be stronger. 44...Rxa3?! Now Black cannot stop the white pawns. 44...Ra2! wins a tempo and it is not clear whether White can win after 45.Ke3 45.Re5 Rxa3 46.Nd4 Ra2+ 47.Kf3 Bc4 48.g4 Bd5+ isn't clear either. 45...Rxa3 wins, e.g. 46.Kd2 Bf5 47.g4 Rd3+ 48.Ke1 Be4 and Black offers strong resistance. 45.Ng3 Ra1 46.h6 a3 47.Rg7 a2 48.Nh5+ Kf5 49.h7! On top of everything Black's king is caught in a mating net.

50...Bd7?! 50...Kd6 51.Kd4 seems to be better for White but it is hard to see how he can make progress. 51.g4 a4 52.gxf5 Rf6?! 52...Bxf5! 53.Bg4 Rg5 54.Rxh6 Bxg4 55.hxg4 Rxg4 56.Rh5+ Kd6 57.Kf3 Rg8 58.Rxb5 Rh8 might lead to a theoretical draw. 53.Be4 Now White is a clear pawn up. Be8 54.Rh4 Bd7 55.Bc2 Bc6 56.Rd4 56.Rg4 Bd5 57.Rg6 Rc6 58.h4 looks more forcing. 56...Rf8 57.Be4 Rc8 58.Bxc6 Rxc6 59.Rd8 Rb6 60.Rc8 Giving Black the f-pawn to penetrate with the pieces. Kxf5 61.Rc5+ 61.Kd4! wins immediately, e.g. Kf4 62.Kc5 Rb7 63.Kc6+- and the black pawns on the queenside will quickly fall. 61...Ke6 62.h4 62.Kd4 Rd6+ 62...Kd6 63.Rh5 Kc7 64.Kc5+- 63.Ke4 Rd2 63...Rb6 64.Rd5! Rb8 65.Kd4 64.Rxb5 Kd6 is not clear. 62...Kd7 63.Kf4 Rf6+ 64.Kg4 Rg6+ 65.Kh5 Rb6 66.Rf5 Ke7 67.Kg4 Rg6+ 68.Kf4 Rb6 68...Rf6 69.Ke4 69.Rxf6 Kxf6= 69...Re6+ 70.Kd4 Rd6+ 71.Rd5 Rg6 72.Ke3 72.Kc5 Rg2 73.Kxb5 Rxb2+ 74.Kxa4 Rb3 75.Rh5 Rxc3 76.Rxh6 Rh3= 72...Re6+ 73.Kf3 Rf6+ 69.Re5+ Kd7? Now the white king penetrates. After 69...Kf6 it is not clear how White can make progress. 70.Kf5 Rb8 71.Kg6 Kc6 72.Re2 Rg8+ 73.Kxh6 Now the h-pawn decides. Kd6 74.h5 Rg3 75.Kh7 Rg5 76.h6 Kd7 77.Kh8 Rg6 78.Kh7 Rg5 79.Re3 Rg2 80.Re5 b4 81.axb4 Rxb2 82.Kg6 Rg2+ 83.Rg5 Rh2 84.h7 a3 85.Ra5 1–0

Nepomniachtchi,I2725Wang,Y27301–02016C457th Hainan Danzhou GM3.2

The third winner of the third round was Pentala Harikrishna. He played against Ding Liren and they discussed a heavily analysed and complicated line of the Open Spanish. When the theoretical duel was over Ding Liren committed a number of inaccuracies and allowed the Indian Grandmaster to win the game with a nice tactical idea.

This gives White's b-pawn too much power. 25...Qb7! activates the queen and prevents 26.Nxc4?? because then Black has 26.Qf3 Qxf3 27.Nxf3 Be4 28.Nd2 Bd5 29.Bxc7 Rdc8 30.Bg3 Re8 31.Kf1 Rxa1 32.Rxa1 Bxe6= 26...Rxa1 27.Qxa1 Qf3-+ and Black attacks the bishop on f4 while also threatening 28...Be4 - Black is winning. 26.b5! Be8 26...Qb7 27.Rxa8 Rxa8 28.Qf3 Qxf3 29.Nxf3 Ra2 30.Nd2 Bd6 31.Be3 f5 32.f4± 27.Rxa8 27.b6!± 27...Qxa8 28.b6 Bc6 28...Bb5 29.Qa1 Qd5 30.Qa7 Bc6 31.f3± 29.Bc7 Rd5 30.Nxc4?!

Qc8 31.Qa2± 30...Qa2 31.Nd2 g5?! 31...c4! 32.Re4 Bb7 33.Rxc4 Qc2 34.Qe1 Ra5 gives Black a lot of counterplay - and it is not clear whether White has reasonable alternatives to this line. 32.Nf1 32.c4! Rd4 33.Qc1 Qc2 34.Kf1 Bb7 35.f3 Kf8 36.Qxc2 dxc2 37.Ke2± 32...c4 33.Qd2 Qa8 33...Qxd2 34.Nxd2 Rb5 35.Nxc4 Rc5 36.Nd2 Rxc3= with counterplay. 34.Ne3 Rb5?! 34...Rc5! 35.Kh2 Bb7 with counterplay was better. After e.g. 36.Nf5 Rxf5 37.gxf5 Qa5 the white squares in White's camp are terribly weak. 35.Nxc4 Bh1 But White can parry this counterattack. 36.Ne3 Bc5 37.e7!
