K.O.T.H. Katchoo vs Phoenix-D, 2406.4; Katchoo surrenders.
This was on one of the Tesco maps, with lots of Rock None medium moons. Fortunately neither of us took that type. The map also had warp points..lots and lots of warp points. The resulting geometry scared the crap out of me early game, because it made defense difficult.
So I went for speed and dropped a lot of weapons platforms along the way. In the end I think that's what made the difference- I captured more systems faster; Katchoo filled his systems up, I concentrated on getting as MANY systems with 1 or more colonies as I could. It helps when in the end-game your ships are speed 9 (JP + prop. experts) while your opponents are speed 6 (ion engines)..
He also listened to Fyron a little too much.

Didn't deploy a single weapon platform. the result was my fleets running unchecked except by his fleets, while several of his fleets were bLasted apart by my platforms.
