The 2014 Asian Nations Cup is underway in Tabriz, Iran, and will run from May 20-30, 2014. It is a team event with men's and women competitions in blitz, rapid, and standard time controls. The first event is the rapid games competitions followed by the standard time controls, and finally on the last day the blitz event will be held.
Standard competition
Open - Rounds five and six

The Iranian media has been providing ample coverage
In the Open competition, China had been leading with not only an impeccable score, but had been beating strong rivals with huge scores. Consider its 3-1 victory over the Vietnamese team, fielding Quang Liem Le (2712) or the 3.5-0.5 win over Kazakhstan. However, round five was the true clash of the titans as the Chinese team played the only rival left: India.

Piece play
The first decisive turning point was the quick win by Krishnan Sasikiran over Yu Yangyi on board two.

most common continuation.} Nc6 {Although it threatens to win a pawn with Na5,
this move looks quite superficial. It blocks the c-pawn and places itself in
the line of fire of White's central pawns.} 6. Qc2 Na5 {Seriously? Since White
already moved the queen out of the way, and plans to push e4 anyhow, why on
earth is Black wasting time on this when it doesn't actually place White under
any pressure, and squanders development tempi.} 7. e4 Bb7 8. Nc3 c5 9. d5 {Now
the question is how does Black solve his queenside since the knight is
somehwat stuck on a5 with nowhere to retreat to. White is already considerably
better.} exd5 10. exd5 Be7 11. Bd3 Ba6 12. b3 O-O 13. O-O Nb7 14. Re1 Nd6 15.

but White is having none of it.} g6 18. Re3 Nh5 19. Rae1 Ng7 20. g4 {White is
probably winning already. Not only does he have more space and a clear attack,
but Black's bishop and rook cannot come to the defense meaning he will be
outnumbered when the showdown comes.} Bb7 21. Qd2 a6 22. a4 f5 23. Bxd6 Rxe3

This put enormous pressure on the Chiense to restore the balance on other boards, but their lower-rated third and fourth boards were only able to draw, leaving their fate in Ding Liren's hands. Ding Liren (2714) was the favorite against Sethuruman, who came rated 130 Elo less, but unfortunately for him, he squandered no fewer than three clear winning continuations in the endgame, and drew by repetition.
