might also look like this
(5)r1c1 = (5)r9c1 - (5)r9c5 = (5)r8c5 - (5=8)r8c9 - (8=1)r2c9 - (1=3)r3c8 - (3=5)r3c6; r3c3 <> 5 |

Or, you could use the 358 XY-Wing in r1 and c8, transporting the <5> from r7c8 to r9c1 and eliminate <5> from r1c1. |

For a one-trick pony, there's always:
Code: | W-Wing: [r3c3]<>1 [r3c3]=5 [r7c3]<>5 [r7c8]=5 [r5c8]<>5 [r5c8]=1 => [r3c8]<>1 -or-
M-Wing: [r3c3]<>5 [r3c3]=1 [r3c8]<>1 [r5c8]=1 [r5c8]<>5 [r7c8]=5 => [r7c3]<>5
|
Personally, I like the (3-step) traditional approach:
Code: | UR Type 1 [r46c37] [r6c3] <> 78
X-Wing c38\r17 [r17c2] <> 8
XY-Wing [r3c3]/[r2c1]+[r7c3] [r1c3] <> 8

I passed up the UR and used three XY-Wings, two of which included transports. |
