Hi Bat,
As you know, I'm a slow learner on this 'multi-house' ALS technique.
Would you mind 'decompressing' your second node to show the detailed linking?

Sudtyro2 wrote:... detailed linking...

imho with this puzzle it's not appropriate to think about "detailed" linking, only the strong link (4=3)r5c468,r68c4.

Explanation...
r5c4,r5c6,r5c8,r6c4 and r8c4 is a subset of five cells that is restricted to the six candidates 1,3,4,5,7 and 9.
When 4 is excluded the five cells are populated by selecting from the remaining five candidates.

With this puzzle I see only one way to do it.
(3=4)r45c3 - (4=15793)r5c8,r5c4,r8c4,r5c6,r6c4 => -3 r4c46,r6c3; stte

'-------------'----------------------'-----------'

A different way of looking at it starts with r56c4, which is an AAALS. That is then doubly linked to the ALS in r5c8 and also doubly linked to the ALS in r8c4. Three extra digits plus four links allows us to treat it as an ALS for chain purposes. Which allows you to write:

(3=4)r45c3 - (4=9)r4c6 - (9=3)r56c4[r8c4,r5c8] => -3 r4c46,r6c3; site
(Though I have no idea if that notation for r8c4 and r5c8 is correct.)

Hi, Steve. I have no problem with Bat's notation or with his explanation above. However, another way of writing it that you may find easier to follow would be:

(3=4)r45c3 - (4=19)r5c68 - (1|9=3)r568c4

Multiple thx to Bat, Jason and Steve...
I know you all are right, and I WILL eventually figure this out...
In the meantime, the ACC tournament looms...
