This is another one that I solved with all the finesse of a bull in a china shop.
There was a Finned X-Wing, Skyscraper, W-Wing, couple of X-Wings and an AIC. Then, looking at the implications of the 19 DP in boxes 23 produced a common outcome which reduced the grid to a BUG+1. |

I needed five wings - and removed a few extraneous ones....
| Code: | x-wing(8) c1, c9 ; r1c8<>8, r5c368<>8
xyz-wing(14-3) r3c2 ; r3c3<>3
w-wing(34) ; (3=4)r3c4 - r3c2=r1c1 - r5c1=r5c6 - (4=3)r8c6 ; r2c6<>3
w-wing(18) ; (1=8)r2c6 - r4c6=r4c3 - (8=1)r3c3 ; r2c2<>1, r3c5<>1
xy-wing(46-8) r5c6 ; r4c3<>8 |
