A deep DTL shot is the best choice here.
usually angles and CC is the best option in tennis but if you do that as an approach you will give him a lot of open court.
so I would approach DTL and deep. If you do you force him to a good short angle passing shot or very good DTL because you cover the long cross and DTL pretty good.
to keep him guessing hit an occasional short cross but aimed more for a winner than an approach.
on a cc aproach you have to cross the whole court to get in position at the net
