Ah wow, very cool for X Liu!
INTENSE!! ~14:50 - 15:01
Hi I saw the vid
Among the vids, this is maybe the one against the better opponent perhaps i've seen, and he's playing a classical game, so you can show some of your best shots.
Your BH attack is indeed your strongest shot, the form is short, its fast low and very spinny, very effective and the placement good as well ! i was for example impressed by 7'05 . at 8'30 you make two excellent ones in a row in the same rally. and you even easily step a little bit to the ball to hit a good shot.
the main problem that i see with your BH is that even in those two rallies, the guy served long on you, and you pushed the ball. Thats ok with players of that level, but your BH is strong, you should be able to attack the first ball. You don't need to put as much power, but just try to play with spin and consistency. Throughout the match you push back a lot of serves and sometimes they pop up a little bit, the push is a bit high, against a higher level player, you would get punished for that, which would be a pity because you have the shots to avoid that.
Also, even if your BH consistency is high, i still saw some mistakes on your BH side
but good FH when you're well placed especially on pivot like 6'50, but you struggle more when its played wide. you have a good reach so you can hit with good power within your hitting zone even when the ball s played on your FH but its clearly less consistent and i feel a good block or FH counter played wide or down the line would cause you some problems. the main problem is the footwork, and thats due to your knee i guess.
for example
FH misses 8'03 (pivot) 8'24 (wide)
The other strong point that i see is that your serves are most of the time low, and there is good variation with the BH, and your 3rd is quite good, you know well where the ball is going.
As for your opponent, his Penholder block is annoying. its coming quite fast in the diagonal to your BH but you have no problems on those fast balls. But he doesn't manage to play so often down the line, it means he's got some problems with your BH spin. He is not so young and his footwork is quite bad. He might have been a better player when young.
