Not sure why I stuck at this one, because I found nothing elegant! It took me two chains to break it open for some "normal" advanced moves...
From Marty's grid...
I had high hopes for the first move as it eliminated a bivalue .. but just a dent
| Code: | | ANT(348)r8c239=(7)r8c9 - (7=4)r2c9 - (4)r2c45=r3c6 ; r8c6<>4 |
Another ugly m-wing-like chain which does some minor but sufficient damage...
| Code: | | (8=5)r4c3 - (5=14)r13c3 - (4=2)r1c2 - r1c8=(2-8)r4c8=r5c8 ; r5c2<>8, r4c8<>8 |
Home straight...
| Code: | w-wing(34) ; (3=4)r3c9 - r3c6=r5c6 - (4=3)r5c7 ; r3c7<>3
xy-chain ; (2=4)r1c2 - (4=3)r9c2 - (3=1)r9c7 - (1=2)r3c7 ; r3c2<>2, r1c8<>2
skyscraper(4) r1, r9 ; r3c2<>4, r8c3<>4 |
