Hey Luiz, yeah in this case it is really difficult. To be honest we all play an opponent like this sometimes where you feel lost and no idea what to do and sometimes it’s just that the opponent is stronger than you at the moment.
But sometimes there are a couple of things you can do to try to avoid this happening. One simple thing is to try to really target strong attacks into their body, if you get the placement of these shots right they are very hard hard to return with good quality. This will make it much harder for him to counter attack you all the time.
If he was attacking every ball as well then it’s very important to keep the game tight and force to at least attack over the table with a flick which will be much weaker than if he can play a strong topspin. To do this you need to work on really tight and low backspin serves and of course also playing a very short touch when you return his serves to stop him getting in an attack then as well.
I would say for now these are the main, more simple things you can try against this player or someone similar you find.
I hope that makes sense and let us know if you have any questions.
