That's what I used. Could someone post the puzzle after basics so that I can see the W wing?

Didn't see that.....I saw the 8s in C7.
My original solution was the XYZ wing.

There is an interesting UR. After basics:
Code:
+-------------+-------------+-------------+
| 1   7   58  | 3   2   9   | 6   458 48  |
| 4   2   358 | 1   68  56  | 9   7   38  |
| 6   9   358 | 58  7   4   | 2   358 1   |
+-------------+-------------+-------------+
| 9   5   6   | 2   4   8   | 3   1   7   |
| 38  138 2   | 57 1-36 57  | 4   68  9   |
| 7  1-38 4   | 9   136 36  | 5   2   68  |
+-------------+-------------+-------------+
| 38  4   1   | 6   5   37  | 78  9   2   |
| 2   368 9   | 478 38  1   | 78  346 5   |
| 5   368 7   | 48  9   2   | 1   346 346 |
+-------------+-------------+-------------+

For the 13 UR in R56C25: Either one of R56C2 is 8 and / or one of R56C5 is 6. Eliminating 3 in R5C5 and R6C2.

Not that it helps. Crying or Very sad

 brR_b-_-r (3=8)r8c5 - r9c4 = (8-3)r9c2 = (3)r9c89  =>  r8c8<>3
 crC_b-_-r (8=6)r2c5 - r5c5 = (6-8)r5c8 = (8)r13c8  =>  r2c9<>8

 W-Wing (8=5)r1c3 - r2c3  = r2c6  - (5=8)r3c4  =>  r3c3<>8
 W-Wing (8=5)r1c3 - r1c8  = r3c8  - (5=8)r3c4  =>  r3c3<>8
 W-Wing (8=6)r2c5 - r2c6  = r6c6  - (6=8)r6c9  =>  r2c9<>8
 W-Wing (8=6)r2c5 - r5c5  = r5c8  - (6=8)r6c9  =>  r2c9<>8
 W-Wing (8=6)r2c5 - r5c5  = r6c56 - (6=8)r6c9  =>  r2c9<>8
 W-Wing (8=6)r2c5 - r56c5 = r6c56 - (6=8)r6c9  =>  r2c9<>8
 W-Wing (3=8)r7c1 - r9c2  = r9c4  - (8=3)r8c5  =>  r7c6,r8c2<>3   Marty's
