i would still keep my distance, I would use my fighters, and corvettes to harass the imperials just enough so they would have to send fighters out to protect. Then i would target there fighters. My main goal would be to take out all of the enemy fighters without engaging with my capitol ships at all. IF they launched bombing runs on my ships i would take out the bombers first. I would do it carefully trying to save as many of my fighters as possible. Then once their fighters were gone(or their numbers were low) I would launcher bombing runs on the ISDs to try to force them to retreat. We all know ISDs are vulnerable to fighter attacks. If my fighter losses started to mount i would move my corvettes in against the imp fighters.
