XY-Wing 27 29 79 pivoted in r4c7; r5c7<>7 solves it.
Also Type 4 UR 45 in 35; r56c5<>5.

Play this puzzle online at the Daily Sudoku site

There's an X wing on 2s Rs 1 and 4 which removes 2s in r3c7, r5c7 and r6c4.
This exposes double 239 XY wings pivoted on r3c7 or r4c7 either of which
does the trick. I thought this was a nice puzzle.
