The last round of Hainan saw some interesting chess. The key battles were certainly the games of Bu Xiangzhi and Ding Liren who were playing for the title, but a curious game happened between Naiditsch and Ma Qun:

Naiditsch can consider himself lucky with a last round draw in a bizarre game
Back to the top boards Bu Xiangzhi drew Yu Yangyi. Yu Yangyi probably wanted to stop the bleeding after three consecutive defeats while Bu Xiangzhi was certainly happy with a last round draw with Black. A solid Petroff saw many simplifcations and an early draw.
A solid draw suited both just fine
This gave Ding Liren the chance to catch up with Bu Xiangzhi, and he did not squander it:

Ding Liren didn't let the Black pieces stop his attempts to win the tournament
The other boards saw mostly solid draws. Ponomariov probably missed a win against Zhao Jun, and almost landed in a lost position. His passed d-pawn gave him just enough counterplay to hold a draw.
Ponomariov's 5.5/9 gives him a performance rating exactly equal to his actual rating
Ding Liren started with the number one pairing seed and finished number one!
At the end of the day Ding Liren barely edged out Bu Xiangzhi in the tiebreak system. These two players were a full point ahead of the foreigners Naiditsch and Ponomariov who had decent tournaments.
Overall the Hainan Super-Tournament had some very unsual and fun games, the mix of players was well balanced. The tournament is also a good omen for China as they gain their fifth 2700 player with Bu Xiangzhi re-joining the ranks of the elite. China's Olympic team in Norway will be fierce; can they pull of a surprise win?
