My post basics grid:

+----------+----------------+-------------+
| 1 7 8 | 9 234 234 | 5 24 6 |
| 46 5 2 | 1 8 467 | 3 9 47 |
| 3 46 9 | 246 5 2467 | 1 8 ...

Regarding the Draw/Play hint of 3 at r7c1.

From the posted position,

+--------------+-----------+------------+
| 78 4 3 | 2 9 5 | 78 1 6 |
| 5 168 178 | 678 4 78 | 3 9 ...

Not sure which W-wings Marty found, but the one I see produces the
same elimination as the XYZ and breaks things free.

I prefer the W-wing on <89>s that solves R9C6.

The easiest VH in recent memory, I think.

There are a couple of different XY-wings and a couple of
W-Wings after the first XY-wing that Earl noted, any one of
which breaks the whole thing open.

Basic technique got me here:

+---------+------------+-----------+
| 1 35 8 | 9 2 56 | 7 36 4 |
| 9 6 4 | 7 1 3 | 8 2 5 |
| 2 35 7 | 68 4 58 | 1 9 36 |

jLo,

Let me know if you need more clues.

Thanks, I see it now.

I had not seen the finned X-wing, so I still had a <5> at R8C2 that was
killing all three of those chains.

I'm not seeing any of these X-Y chains before 5 is eliminated from R5C8.

Someone give me a clue.

Oops!
That makes it very truly VH!

After doing Marty's XY-wing and a skyscraper on <7>s to eliminate
<7> from R1C7, you end up here -

+-------------+-------------+------- ...

Since todays VH went too smoothly, I found one that was truly VH.
Any one see the next move?

How did you eliminate 5 for R5C8?

So is it rare or normal that two strategies overlap each other, with the exact same eliminations?

Very common.

I found myself unable to get past the following point:

+------------+----------+----------+
| 8 36 369 | 5 1 29 | 23 4 7 |
| 17 167 469 | 3 69 249 | 28 68 5 |
| 2 5 346 | 8 67 47 | ...

Could someone tell me where to go from here please?

Look in Box 4 for the pivot of an XY-wing. Once you spot that you will be done.

One xy-wing and one UR did it for me.

Oops, my UR was not quite valid.

I still think it is nothing but singles from Earl's position though.

Take your time. It can be solved with x-, xy-, W-wing, UR and strong links (also 3 or Color wing).

One xy-wing and one UR did it for me.

From Earl's position -

+---------------+-------- ...

Something hidden and something tall will get you to the same place
as the fish.

If we color <7> in @ red, then the <6> and <2> in the right column are red by XY Chaining. Now notice that the bottom left cell can see both red <7> and red <2>. So, th ...

Keith's posted grid has <179> at R3C5.
Would it not be required to eliminate the <1> in R3C5 to have a valid skyscraper?

The skyscraper is down columns 6 and 9.

Two <1>s ...

Are you sure you didn't correct it too much?

If you had seen the original post, you would have seen that it
was much much easier. Smile

Can you point it out?

<1>s at R3C6, R3C9, R7C6, R9C9 - eliminations at R9C5 and R7C7.
