Just wanted to throw this out there for the community, since I've used it a few times now and I'm loving it so much. It's no revolutionary tactic or anything, but might be helpful to those who, like me, haven't historically run Yavaris B-wings much.
If you're running Yavaris + B-wings as player 1 and your opponent offers you Fleet Ambush as an option, take it. Deploy your first ship--not Yavaris--a short distance back within the ambush zone, trying to draw your adversary into deploying at the leading edge of their deployment zone. Which, most will be more than happy to oblige, because you don't take Fleet Ambush without thinking "woo hoo hoo, they've fallen into my trap, and now they'll pay!!" Then you deploy your second ship as far forward as you can, at top speed charging into the combat area (nothing revolutionary here).
Finally, you throw down Yavaris. By this point your opponent has had two opportunities to place ships at or near the forward edge of his deployment area, which means there's probably at least one ship in range. So you drop Yavaris as far forward as you can, pointing directly at him (keep dem front shields relevant!), , and then deploy your B-wings in Yavaris' activation range between her and the target, and cut loose.
I got the alpha strike on my adversary's AF2 flagship the other day with this tactic. Opening the game with 6 goddamn B-wing shots is a pretty soul-crushing situation to be on the receiving end of.
