The following observations are of course my personal view and do not claim to be the “truth”!
Here comes Kim Youjin (Korea):
- good backhand defence/chop
- good footwork
- consistent pushing with forehand, also seem to be quite “choppy”
- good variety of backhand serves
- generally too much defending only.
- forehand defence often come back too high. Technical issue: Like many female defenders she “shovels” round the ball instead of chopping or cutting through the ball or trying a “float”
- forehand topspin missing, especially when confronted with pushes down her forehand
- no or few twiddling of the bat
- generally she should try to get more versatile: Use forehand topspin more often, twiddle bat (use pips in to push from backhand side), use forehand serves, block unexpectly with backhand (either with long pips or pips-in according to the situation)
- improve forehand defence against slow and spinny topspins by either using long pips to defend or taking the ball lower and chop it more than “shoveling” it back.
