I sometimes play with this guy who's serve seldom bounces PAST the service line, his landing point just past the net, with under/sidespin, which forces the returner up into the net, from whence the ensuing LOB will be the next answer, usually within 4' of the baseline, so tough putaway.
Great strategy for baseline bashers who want to stay back and hit with heavy topspin. His bounceheight barely reaches the height of the net, so aggressive returns are not a simple task.
