I'm surrendering. I see an X-Wing on 5 and Finned X-Wing on 1 but nothing else.

Thanks Dan. It's nothing short of appalling that I am missing basics on so many puzzles. Embarassed

After accounting for the quad in box 6 it becomes a pretty easy puzzle, with the XY-Wing (784), pivoted in r1c1 being all that's needed.
