Opponent opens up a rally with a heavy topspin

Hello,

I've got a question on what to do when an opponent opens up a rally after a push to push exchange with a heavy topspin. So normally I try to open up first, but sometimes the opponent is just quicker. So what to if it happens? Of course I can block it with a more closed bat angle, but then an opponent gets an easier ball to attack after the block. I try to be brave and counter that heavy topspin but most of the time it goes off the table.
