I’ve recently been reading (and thoroughly enjoying) the Reality Dysfunction by Peter F. Hamilton. The ships in this setting need to be far enough away from a gravity field to use their version of Jump safely (as with Traveller). One of the characters pulls of a jump from a world’s Lagrange point as the moon and planet’s gravity fields cancel each other out. It was a risky manoeuvre for the ship because it was done at high speed but I thought it could be an interesting smuggler/pirate trick in Traveller.
