The 2nd set does look eerily similar to the first. TH leading but running out of gas towards the end.
KILLING finishes of the sets from LD. from 10 12 to 20 16 in the first and from 11 7 to 14 20 (!!) in the second I think TH had been getting tired at the end of the set ..
Super Dan has a very good gearbox. It seems he can control his tempo with unlimited degrees of freedom.
It's the way Lin Dan always plays. Never be fooled if he's behind early on. Wait until after the interval!
