Two rounds into the super-GM tournament in Danzhou, China, three Chinese players lead with 1.5/2: Yu Yangyi, Wang Yue, and relative old-timer Bu Xiangzhi. Surprisingly, top seed Ding Liren is tied for last with just half a point, but with seven rounds left that's obviously likely to change. In round 1 he missed Ian Nepomniachtchi's interesting way of combining central play with e5 in conjunction with the advance of his a- and b-pawns, and in the end White's a-pawn led to decisive material gain.
Also in round 1 Wang Yue defeated Hou Yifan with surprising ease. Hou's allowing her queenside pieces to be arrested by a white pawn on c6 may not have been fatal by itself, but at a minimum it reduced her margin for error. She managed to liberate her game somewhat by sacrificing the exchange for a pawn, but in the end White's extra material mattered.
The third win of the first round was Bu's win over Pentala Harikrishna, with the black pieces. Hari's position was always safe, and a draw was there is he had wanted it. He wanted more, and as sometimes happens, got less. 29.h3 was a bit dubious, cutting off the rook from Black's b-pawn after 29...Bd1, and 30.e5 was just an error. Both players made inaccuracies in the ensuing play, but the general trend was always in Black's favor, and Bu's win was the logical result.
In round 2 Yu defeated Nepomniachtchi when the latter pushed too many pawns. Sometimes pushing pawns is a good way to gain space, and sometimes it's a way to get overextended and create weaknesses. For Nepo the second story was the one that got told. His queenside disintegrated, and there was nothing concrete on the kingside to compensate for his material losses.
Of the hitherto unmentioned players, Wang Hao, Vassily Ivanchuk, and Peter Leko have drawn all their games and thus have 1/2.
