side-spin-and-side-underspin-serve-receive

Hi so generally on a Long Side Spin serve usually what i play here in Is a slow spinny topspin and the same Is mostly on a Long Side underspin serve my question is on These Kind of Serves should i Sometimes learn to Play immediately strong Topspin Attacks in against these Serves of It will be always fine to Play a slow spinny Attack in. And the Same to short Side Spin and Side underspin Serves is It Just Always fine to Play First a slow spinny flick in or its better to Sometimes against these Serves Play in a flick with much Power and Speed. And also maybe should i Sometimes Push the Side underspin serve or really i should only try to Play a slow spinny Attack in or as i sad maybe playing sometimes a ball in with full Power there ?
