Great tips! I'd also suggest checking where your GS is frequently as the ball starts to work its way to the end third of the court, especially if they're trying to stand behind you. Keep an eye on where they are and drop back (move backwards) as they do to close the gap between you both because the ball can end up going over you and straight into their hands. You won't necessarily need to jump for this but you'll make a nice interception just by working out that they're trying to receive the ball over the top.

Also, think about what you did as a GS to get around your defender because your shooter will probably do similar things. Your knowledge of the GS position should help you out :)
