im currently watching cai yun's review for the world championship...

chentoh really targeted yaya's backcourt so well. 17 flick serves - 5/6 was missed. he said most important thing in doubles is serve & receive - taking initiative, the win rate is 30%. offense increased it by 20%, and defensive counterattacks by another 20%.
when shengshu did flick serve at 19-20 during the 2nd game, she shouldve be more stable and less anxious than pearthin. pearthin just lost 1st game and might be off-guard when the score equalize but the service error at 20-20 really cost her a lot.
