Focus on <7> eh!
An x wing on <7> did much damage followed by two ERs on <7> and an xyz wing and an xy wing that also removed <7>s.
But somewhere in there I also used an ER using the two <7>s in C8 and extended pincers from Box 5 to Box 1 which whacked the <7> in R7C4.
All in all - quite brilliantly executed

xy-wing <246> with pivot <46> in r9c6

XY-Wing on 267 and XYZ on 247 did it for me.
