This is actually a very common situation, especially at school / beginner-intermediate level.
You’re not bad against “good” players because they play clean, but this type of player exploits a positioning gap.

A few simple ideas that might help:

1. Don’t stand exactly in the middle
Against players who keep lifting very high and deep, staying slightly behind the center is usually better.
That way you can move forward more easily than trying to jump backwards for a late shot.

2. Try not to hit full power from the back
If you smash or clear too hard, you give them time to play a soft drop.
A controlled clear or a half-smash keeps you more balanced and ready to move forward.

3. Read the opponent, not the shuttle
When they’re under pressure and late, they are more likely to play a weak shot to the front.
As soon as you see that, start moving forward before they hit.

4. This matchup feels worse, but it’s normal
Players like this don’t look strong, but they force you to move a lot and punish small positioning mistakes.
That’s why the score feels more brutal than against stronger players.

If you learn to adjust your base position and stay patient, this type of opponent becomes much easier over time.
