KKK/TBH had themselves to blame. Taking the OG SF lightly. Both look sleepy. It's the organizers fault for scheduling the match so early in the morning.
JJS smash is not much harder than Bo/Mo's. but the diff is the the Korean can return BoMo smash, but not the other way around.
Definitely, Cai/Fu never let up in the big tournaments, play every rally solidly and never let up in the opponent.
CJS's smash is quite deadly and have many chances to do it on the other hand DEN pair looks stress. 7-11 on Korean favor.
Finally DEN pair able to overcome their "load". They returned the shuttlecock to the a good place therefore they could initiate their attack. Before they returned the shuttlecock to the place CJS was waiting. 14-15 for KOR.
