I always liked Calhoun's solution. Obliterate the Maru. It's either a trap or it's not. If it is, you don't want to leave it there for someone else to fall for. If it's not, you don't want to leave it there to cause a diplomatic incident, and fiery plasma death is probably better than whatever the Klingons / Romulans would do to the crew.

Of course, I don't recommended launching a full spread of photon torpedoes at your gf.
