An unhappy birthday

A few months ago I published a drastic loss by Yasser Seirawan from the US Championship. Conventional wisdom was that outdated opening knowledge, caused by a lack of constant tournament play was the reason for the loss. It looks like he has decided to play a little bit more as he has turned out for the United States in the World Teams Championship being held in China at the moment.
In round 6 he played Judith Polgar, who was celebrating her 35th birthday. Showing her no favours he scored a pretty one sided victory, finishing with 2 rooks versus a knight. He then continued his good form with a win in the next round over Mamedyarov.
