The first move I found was an AIC, abcdefg, while looking for xy-wing......

Code:
 *--------------------------------------------------*
 | 2    1    9    | 8    3    5    | 7    4    6    |
 | 4    7    3    | 16   2    16   | 8    5    9    |
 | 5    6    8    | 4    9    7    | 2    1    3    |
 |----------------+----------------+----------------|
 | 78   3    6    |g19   58   2    | 159  79   4    |
 | 78   9   d45   | 13   568 e134  | 156  2    578  |
 | 1   c25   245  | 7    568 f49   | 3    69   58   |
 |----------------+----------------+----------------|
 | 3   b28   27   | 5    4   a89   | 69   679  1    |
 | 6    4    1    | 239  7    39   | 59   8    25   |
 | 9    58   57   | 26   1    68   | 4    3    27   |
 *--------------------------------------------------*


(9=8)r7c6-(8=2)r7c2-(2=5)r6c2-(5=4)r5c3-r5c6=(4-9)r6c6=(9)r4c4; r8c4<>9

Later I took a second look and found another one step solution
Quote:
anp(58=7)r56c9-(7=9)r4c8-r4c4=r6c6-r7c6=r7c78-(9=5)r8c7; r8c9<>5

[Edited to add second solution]

There is a classic M-wing (look at 69) that takes out 9 in R7C6.

I finished with that M-Wing, but before that I saw a W-Wing which I played.
