I found three moves and they completed the puzzle.

Quote:
An AIC that I found looking for a xy-wing: (2=4)r5c4 - (4)r6c5 = (4)r7c5 - (4=2)r7c6; r5c6<>2,
A second AIC that I also found looking for a xy-wing: (4)r5c6 - r2c6 = r2c9 - r6c9 = (4)r5c7; r5c6<>4,
type 1 UR18 in r78c17.

I used two, the first a skyscraper on stilts: Very Happy
Quote:
(8)r4c9=(8-1)r8c9=(1)r2c9-(1)r2c6=(1-8)r9c6=(8)r5c6
=> r4c5,r5c7<>8
skyscraper 4

I can always find a way to use more moves and this was no exception. X-Wing on 6, two simple colorings on 4, W-Wing on 24 and finished with an ER on 4.
