xyz-wing in box 2 {2,7,9} removes 9 in r3c4
grouped strong link w-wing {7,9}
(9=7)r8c4 - (7)r31c4 = (7)r3c5 - (7=9)r3c1; r8c1 <> 9
then if you like them super-sized
(1=9)r7c9 - (9)r9c7 = (9)r9c5 - (9)r8c4 = (9-2)r8c3 = (2-1)r8c2 = (1)r1c2 - (1)r1c89 = (1)r2c7; r7c7 <> 1
that should do it. |

6 steps for me: an x, xy and xyz wing, two Typ4 URs and and ER.
Good - but I probably overkilled it. At least I finished it - couldn't get anywhere with the other one today (90) after basics and a UR. |

| XYZ-Wing on 279, W-Wing on 79, then the same wing with pincer transport, then the same cells again, but this time with pincer of 9 rather than 7. |
