(1) Van Wely,L (2677) - Giri,A (2672) [A11]
4th NH Chess Tournament Amsterdam NED (4), 15.08.2010
White's move order is an attempt to delay the obvious d4, leaving it as an option, while gaining time with other aspects of his development.
The most oft played move here is actually 6...Bd6 but Giri has decided that if White is going to leave the e5 square up for grabs, then he might as well grab it.
Now White gets nothing if he plays slowly, so Giri was not surprised when Van Wely opted for this aggressive move.
Before playing 10...e4, Anish had briefly analyzed this sacriice and concluded it was 'rubbish' (ever known the young to mince words?), but nor was he shocked to see Van Wely play it anyhow. It was a practical decision, and things were not easy for Black as it were. [11.Nd4
would hardly be an improvement.]
Though Black is objectively ahead, considerably so, he has his work cut out for him.
[Taking with 21...Qxd2+
would be far worse, as it would allow White a ton of play. 22.Kf3
and suddenly Black is so tied down, it is he who is in danger of losing.]
