Hou Yifan employed a rare and interesting plan in the Sicilian Najdorf with 8.Qf3 and 9.h4. Anna Ushenina has spent almost half an hour thinking how to react. On move 14 queens were traded, and rather soon it became clear that White has obtained a clear positional edge, while Black found herself in severe time trouble. However, later on Hou Yifan made a few careless waiting moves and let the advantage slip away. On move 31 a draw by three-fold repetition was claimed.

Rollerblading

Grandpa Grumps had just informed the local police that several children were rollerblading in his driveway. However, by the time Police Officer Nickham turned up the children had gone and Grandpa Grumps couldn't remember their faces. So Nickham rounded up five children in the neighbourhood who had seen the culprits and listened to what they had to say about each other.

            "Exactly two of us are liars," said Andy.

            "The next person to speak is a liar!" piped Babs.

            "Exactly two of the others lie," said Connie.

            "Eddie tells lies," claimed Danny.

            "Exactly two of us tell the truth," said Eddie.

Which children can Nickham be sure to get reliable statements from?

Here I am in Bucharest, on my way to the WJCC, which will take place in Kocaeli, Turkey. I expect to arrive in Kocaeli this evening (September 12), as the 1st round is already tomorrow, at 3 pm local time.

It is my last year when I am still a junior and I've already played for 3 times in these championships (2005, 2011, 2012), so I guess that I can say that I'm a "veteran" of these tournaments.
