"Simplest" pattern path I could find was...
x-wing(1)c49/r19 ; r1c18<>1, r9c158<>1
xy-chain-ish (7=2)r9c5-(2=1)r9c4-(1=2*)r1c4-(2=5)r1c1 ...

Most straightforward approach I could find...
#1 finned-x-wing(4)r68/c14,r8c5 ; r7c4<>4
#2 kite(7)r4/c3 ; r7c4<>7
#3 turbot(7)b6/c3 ; r7c9<>7 { Marty' ...

Seems to be infected with malware again ... or is it just me?

The puzzle seems to be available at the old [url=http://sudoku.org.uk/WeeklySudoku.asp]site but the forum accessed from there is jibber ...

I will be in England next week. A country whose primary redeeming features are this discussion list and the quality of the Sudoku puzzles in their generally free daily newspapers.

Or just an h-wing...

h-wing (4=9)r9c3-r1c3=(9-3)r1c2=r9c2 ; r9c2<>4

On that site it was "tough" (and they get really tough!) - I guess it wouldn't register with SE.
It's not often you see a house with 8-cells and a quin/hidden triple.

I think it got hit by some virus? I went there and my Corporate-McAfee went bonkers blocking some access to ".ru" URL (never a good sign!)...

Now it seems clean but the thread titles and ...

Selective memory doesn't worry me... best to ignore the collateral damage of chains and use the outcomes that are helpful!

Anyway it was only a bit of fun - I think I initially had an l-wing and th ...

Long time... Hi!

Seems pretty quiet on all Sudoku forums I frequent! Maybe people actually have a life and go on their boats/cottages/holidays in the summer - or maybe they only post when they get back to their office ...

Not as impressive as Keith's DP, but still interesting.
Very interesting! I have all bit given up on hidden rectangles as I have yet to find one that helps the solution.

But assuming it was concerning the strong link on 1 and ...

I don't know if this method has a name, or if it is considered to be trial and error?

As you have described it, I would call it a "contradiction forcing chain". In that you assume a ...

Fun puzzle with lots of moves and paths to try...

First two could be combined as an 'almost' if desired.. final move perhaps a bit "extreme" but effective!

Was there perhaps a move before your skyscraper, to get a strong link on 4 in r7?
I culled one too many when I abandoned my "advanced" path Embarassed

Thanks!

I tried to stay in rating - but after about four back-to-backs ... jumped ship
