It can be solved with multiple advanced steps with no chains, patterns, fins, or "almosts".

It can also be solved with one step using a chain.

I thought I had a one-stepper, but not quite.

XY-Wing (179), flightless, pivot r7c8, transport 9 from r8c9 to r1c3; r2c1, r7c3<>9

Remote Pairs (27), 6-cell; r8c3<>27=6

Easy SE 6.6 puzzle !

So, just for the fun ...

Code:
+----------------------+------------------+------------------+
| 6     7      58(9)   | 45   348    38   | 2    1458   1(9) |
| 5(9)  1      4       | 2    78     6    | 579  578    3    |
| 2     58     3       | 457  1      9    | 567  45678  57   |
+----------------------+------------------+------------------+
| 579   69(2)  5679(2) | 1    37(2)  4    | 567  3567   8    |
| 1     3      (27)    | 8    6      5    | 4    9      27   |
| 8     4      2567    | 9    237    237  | 1    3567   257  |
+----------------------+------------------+------------------+
| (79)  29     2789    | 6    5      1278 | 3    17     4    |
| 4     26     256-7   | 3    (279)  127  | 8    157    1(9) |
| 3     58     1       | 47   4789   78   | 579  2      6    |
+----------------------+------------------+------------------+

(7=2)r5c3-2r4c23=2r4c5-2r8c5=[RP(79)r7c1,r8c5 connected by ER(9C9B1)]
=> SIS(7r5c3,7r7c1,7r8c5) => -7r8c3

Dan, I don't know if that notation represents an AIC or XY-Wing, but it's the same as my XY-Wing with pincer transport. However, it looks like you're staying it's a one-stepper whereas I didn't see how to finish it off without another move.
