Hey Aniket, it doesn’t sound like good conditions at all and of course this is very hard to play well. The only good thing is that it’s the same for everyone so you will all have the same problems. It’s very hard to give tips on how to play on such tables but what I would say is if your a forehand dominant player then try to get this into play as early as possible with a strong topspin and play aggressive to finish the points more quickly.
I would also say stick to simples serves and just keep them short and tight. Lastly, try to put the conditions and the tables out of your mind as much as possible and focus on what you can control, do your best to focus on your game and the individual tactics against your opponents. Best of luck!
