XY-Wing

The three cells G9, I8 and D9 form an XY-Wing pattern on the value 8. Regardless of the correct value of the cell G9 (2 or 7), one of the two cells I8 or D9 will have the value 8 as its only remaining potential value. It follows that either the cell I8 or the cell D9 must contain the value 8.

Other occurrences of the value 8 can therefore be removed from any cells sharing a box, row, or col with both I8 and D9.
