That's the key issue. I believe Towi/Butet can match the CHN pairs. But, its these costly errors that led to their defeat in most cases. Imagine if u are still leading 1-2 pts and the game proceeds on....u will have a better chance to win it.
They should have learnt from Joachim Fischer-Nielsen/Christinna Pedersen, who beat the CHN pair twice in a row.
If 9/10 ppl is of the opinion LD's injury is fake, then there must be something wrong somewhere in the procedure for justifying a pullout from tournaments - either with the leniency of the dr examining or the rules being applied.
