2 in row 9 can ONLY go in box 8(r7c4-r9c6) so you can eliminate 2 from other cells in box 8. So r8c4 becomes 4 or 9.

This creates a pair at r7c4 and r8c4 of {4,9}. So you can eliminate 4 and 9 from other cells in column 4. So r6c4 becomes 2.

After that, I think it's clear sailing.

Thanks - why is it so obvious when someone else points it out? You've restored my sanity!
