Assuming you get pretty fast on the ball that's what I would suggest:
FHand on the corner or right on the feet of your ooponent with some good top spin to clear the net enogh but with not too much power because you may over hit and go out wide o long.
if you are a bit late slice back hand as many mentioned, better if it has some side spin bit it need to be pretty deep
if late Fhand slice driven down the line with very little clerance of net staying low with your legs and driving the bal with your arm. A pro thought me this shot and I love it but it requires a lot of practice.
