Trope-a-Day: Hyperspeed Ambush
Hyperspeed Ambush: Hard to arrange, given the nature of FTL in the ‘verse; it generally requires that the ambushees be approaching or otherwise close to a stargate while your fleet remains at the other side of the pair, and yet and at the same time has access to real-time information about what the ambushees are doing. And then pull off a perfectly-timed low-drift jump.
It’s been done, but opportunities don’t come up all that often.
