### Is it WXYZ Wing

Hello,

1. Can the marked fields be considered as WXYZ-Wing? Pivot is r8c9 and the pincers are r7c89 and r8c4. (Is_It_WXYZ_1.png)
2. If the answer is YES, can the both candidates (6 and 7) be eliminated from r8c78?

Code: Select all
`*-----------*|4..|.2.|..1||...|45.|...||725|916|843||---+---+---||8.2|1.9|6.5||3..|865|..2||5.1|2.3|..8||---+---+---||2.3|594|1..||...|.32|...||95.|.8.|..4|*-----------*`

The problem with answering your questions are, that with the solved cells you have, the puzzle solves with singles, so your questions are moot.

3 in r1c3 is a hidden single in Column 3, 1 is a hidden singles in Column 6, 3 is a single in Column 7, which then forces 2 a single in row 9, and so on until the puzzle is solved. I've shown the first of the singles in the following PM diagram.

Code: Select all

No, it is not a Wxyz wing.. The 4 cells selected do not have a restricted common between the cells.
Some do, some teach, the rest look it up.

I don't think there's a law against trying to spot or use "too advanced" patterns for a given situation, so I don't see the question as moot per se. The answer is clearly no, however, as StrmCkr said.
