As usual, I went the XY wing route.

I played around with the potential 46 DP in boxes 17 and any of the DP killers force the same cell which solves it.

There's also a little w-wing in the same part of the grid..

Quote:
w-wing(25) (2=5)r6c1-r7c1=r7c2-(5=2)r3c2; r6c2<>2

Another possibility that I explored was the 6-cell DP 127 in r45c347. I was able to deduce r4c7<>2, but it was not a productive deletion.

I saw that as well and didn't see much potential.
