X-Wing 3 in line 5 and line 8--> r4c2<>3, r6c2<>3, r9c2<>3 and r9c8<3>
Discontinuous nice loops
If r5c4=7-->r8c4=5-->r8c8=3-->r5c8=7-->r8c4<>7 then -7 r5c4

W-Wing 35 with Strong Link 5 in col 4; r5c8 <>3 and
W-Wing 34 with SL 3 in r5c28; r4c7 <>4; stte |

Thank you Marty for saving what little sanity I have! I knew there HAD to be a 'standard' solution (i.e. involving X-wings, XY-Wings, and XYZ-Wings only) but I didn't see it! Hey, by the way, it's good to be back! |
