What I discovered on lanx was that he was sending is fleet and resources across several galaxies to a planet where I had a planet in the same system. Had to wait almost 3 hours for the fleet to arrive.
Already had some deut there from my earlier raiding. Jumped in the fleet and waited. During my wait, I kept lanxing his planet. Found that he was sending transports to this planet too. Was hoping to slip in my attack in between his transport missions.
With only 4.5 minutes to attack, my fleet sneaked in and destroyed his incoming fleet. Picked up all the DF too. Also gave him a moon .
Good luck rebuilding TheSnake.
