I don't have my book in front of me, what are the effects of being pinned? If one is a movement penalty, he'll get a good bit more than 30% of the time.
Does the Sharlin have a rear NL?
That aside, I would think that you will not be able to approach from the side unless you jump in on him. Sharlin starts in a edge of the map area. If you start out in front of him he simply all stops, if you move in he'll get arc and be eligible for all stop and pivot. If you start out off set, he simply turns into the arc you will approach from and you start again with the above. Yes he's lumbering but that just makes him more a turret than not able to turn.
Second is that you do still have to penetrate stealth, in the case of the shadow and two stalkers that's only maxing out at a reduction of 3 if your standing on him, so 3+ then if you make it 2+ for the other ships... not a big chance, but still an issue. Add in that fighter wing....not a small wing with two sharlins either and the tit for tat starts looking less sure even with primarily mini beams.
Anyway, just don't want the guy thinking it should have been a cake walk for him, it's actually a pretty tough fight, with the first turn going against the shadows most often, second being dependent on if anything got pinned, and only in the third do we start to see clean shadow superiority in placement.
