Hi Shivgaur,
Yes this can be a frustrating problem for a lot of players! There are a few videos we have that will help, of course our forehand topspin against backspin will give you pointers on the overall technique that will help reduce mistakes.
But I would suggest having a look at this video- https://tabletennisdailyacademy.com/videos/half-long/
We speak a lot in this video about adjusting for shorter balls and the body position etc required. Also have a look at out video on how to play a heavy forehand topspin, this will help you generate more spin and safety on your open up shots against backspin.
You can view it here- https://tabletennisdailyacademy.com/videos/table-tennis-hack-the-heavy-forehand-spin/
I hope those are helpful and if you need any more help or have further queries just give us a shout on here!
