Alternatively there’s a BUG+3 pattern

Code:
+-----------+--------------+--------+
| 7  24   9 | 6    24   5  | 8 3 1  |
| 58 35   6 | 1    9    38 | 2 4 7  |
| 48 23+4 1 | 78   34+2 27 | 9 5 6  |
+-----------+--------------+--------+
| 1  45   7 | 45   6    9  | 3 8 2  |
| 45 9    2 | 3    8    1  | 6 7 45 |
| 3  6    8 | 47+5 25   27 | 1 9 45 |
+-----------+--------------+--------+
| 6  1    4 | 58   35   38 | 7 2 9  |
| 2  7    3 | 9    1    4  | 5 6 8  |
| 9  8    5 | 2    7    6  | 4 1 3  |
+-----------+-------------+--------+


Bearing in mind the (24) in r1c2 and (25) in r6c5 this eliminates 2 from r1c5 and leaves a BUG +1.which solves the puzzle.

[r2c2]=35 is connected to [r6c5]=35 by (5).
However, they can't directly produce an elimination.
There's also a strong link on (3) from [r6c5] to [r3c5].
I believe this qualifies as an ...

Code:
 [M-Wing/Chain] => [r2c6],[r3c2]<>3

Naked Singles complete the puzzle.

The "Daily Sudoku Competition" printout is AWFUL.

It should now be possible to mouse-mark, copy and paste those into the formatter, as well as Menneske and Decabit (this one especially for Earl Smile )

Marty,

Thanks. I'm still in the early learning stages of "extended" wings...this one is a good example!
