One Trick Pony 2/17/08

Today's One Trick Pony took me one trick (Turbot) but I had to use it three times.
Can anyone see a single advanced trick that will solve this puzzle?

A W-Wing does the trick, I think.

Candidates (17) are in r1c6 and r9c2. These two cells are linked by the conjugates for 7 in the first column so one of them must contain 1. Eliminating 1 from r9c6 gets you home.

While looking at this pattern I see it could also be a turbot with r3c5=1

Thanks,

Another possibility is a remote pair in r6c15, r47c4 for digits 5 and 9 (eliminates 5 and 9 from r7c1).

Edit: changed r1c7 to r7c1

You are right of course, I edited my post.

empty rectangle

solves puzzle as singles.

EMPTY RECTANGLE: 5 taken off r7c1 - ERI: r4c1, b=r7c4
EMPTY RECTANGLE: 7 taken off r1c8 - ERI: r6c8, b=r1c6
EMPTY RECTANGLE: 9 taken off r7c1 - ERI: r4c1, b=r7c4

i used box/line interactions to get down to the same grid listed above.

then apply one emptly rectangle and it solves as singles via box/line interaction.

another option is the

Death bloossom pattern (used three times. ) (after box line interactions down to inital spot posted above)

DEATH BLOSSOM: ([ALS:r1c6] and [ALS:r4c3|r6c3|r7c3|r8c3]) + Stem:r6c6 means 1 can be removed from r1c3

DEATH BLOSSOM: ([ALS:r3c5] and [ALS:r8c2|r8c3|r9c2]) + Stem:r8c5 means 7 can be removed from r3c2

DEATH BLOSSOM: ([ALS:r9c6] and [ALS:r1c1|r4c1|r6c1|r7c1]) + Stem:r1c6 means 4 can be removed from r7c5
Some do, some teach, the rest look it up.

This one is exactly what I needed -- resulting in singles the rest of the way out. Thanks. Death Blossom is on my study list.
