This was a tournament game in '08. Here were the fleets (sorry I don't quite remember his):
SM
BB - MotF, 2 rerolls
4 SC - squadroned
6 Gladius
3 Sword
IN (as many nova cannon as would fit)
Mars
Lunars?
Dominators?
We rolled for terrain. He placed a planet in the far corner. I placed an asteroid field in the middle. He placed the moon in the other corner. I placed a warp rift about 15cm from the asteroid field, parallel to it. Other terrain didn't matter. He deployed tight in the corner, while I had the SC and Swords behind the rift and the BB and Gladius behind the asteroid field. The scenario involved destroying their priciest ship/squadron, getting extra VP for doing so.
Turn 1 - He burned retros. I stayed put.
Turn 2 - He burned retros. I stayed put.
Turn 3 - He drifted forward slowly. I stayed put.
Turn 4 - He drifted forward slowly. I stayed put.
Turn 5 - He drifted forward more aggressively. Now he's on the other side of the rift, basically, but most importantly his Mars is 9cm from the warp rift and facing it. I finally engaged, sending ships out on all sides to pester. Did a little damage, but the most important part was when the thunderhawks pile-drived into the Mars, breaking its rudder.
Turn 6 - Failing its command check, the Mars drifted into the warp rift and was destroyed. He didn't cause much damage, and I crippled another ship. Epic win to me!
He was relying on me being noobish and running into his big guns. When I didn't, he got visibly angry and came to me...at which point the superior close range equipment of the marines got to him. I don't think the BB even engaged anything, other than with the thunderhawks.
