xy-wing {4,5,8} removes 8 from r7c8 and r45c7
UR type 1 {4,5} removes 45 from r5c7
extended w-wing finishes
(6=3)r3c2 - 3)r1c2 = (3)r1c7 - (3=6)r5c7 - (6)r5c1 = (6)r46c3; r12c3 <> 6 |

I started with an ER 0n 6,
then a xy-wing 458 with pivot 48 in r4c8,
and then, using one of Norm's UR techniques, a UR 67 in r14c79 which forces r1c7=3 or r3c7=4; both result in r5c1<>6 to finish the puzzle.
Thanks Norm for your insights.......

| I used a couple of ERs, the UR, couple of XY-Wings, Hidden UR and a W-Wing with pincer transport. |
