Do you hear alarm bells ringing?
Any house left without a particular candidate, or more that one of a particular candidate forced into a house?
Trivial stream
(7)r5c9 - (7)r1c9
Second stream
(7=8)r456c9 - r8c9 = r8c7 - (8=7)r1c7 - (7)r1c9
=> r1c9<>7
But stop and look...
(7=8)r456c9 - r8c9 = r8c7 - (8=7)r1c7 - (7)r1c9
There are now no sevens in column 9.
Alarm bells are ringing.
