XY-Wing 28-24-48 pivoted in r3c1; r8c3<>8 solves it. |

Yes.
Those who like to work from the bottom up find another xy wing: 245 pinching box 9 cell 1 on 5. But unfortunately that doesn't seem to help. |

| I know it is late for a comment. I have been away etc.. anyway another solution is a W wing 24s in Blocks 2 and 7 operating on 4s in col 3 knocks out the 2 in r1c2 and so gives a solution! |
