No acing means making the most damage to her (when you asked for reinforcements). Ace has a crown next to their name and avatar in the screen after you opened an AW chests. And you shouldn't waste BP on a single AW, if you can't beat her the first time ask for help right away.. rather use the BP on a new one to get more AW chests overall.
