 like a hanging curve ball, this one was a change of pace that was ready to be knocked out of the yard.
| Code: | .------------------.------------------.------------------.
| 9 4 1 | 35 7 358 | 6 38 2 |
| 58 6 35 | 13 2 138 | 9 7 4 |
| 2 38 7 | 9 4 6 | 5 38 1 |
:------------------+------------------+------------------:
| 48 18 35 | 1345 9 135 | 2 6 7 |
| 6 35 2 | 7 8 35 | 4 1 9 |
| 47 17 9 | 14 6 2 | 3 5 8 |
:------------------+------------------+------------------:
| 1 2 8 | 6 3 9 | 7 4 5 |
| 57 57 6 | 2 1 4 | 8 9 3 |
| 3 9 4 | 8 5 7 | 1 2 6 |
'------------------'------------------'------------------' |
(8=1)r4c2 - (1)r6c2 = (1)r6c4 - (1=3)r2c4 - (3)r2c3 = (3)r3c2; r3c2 <> 8 |

I took about five times as many steps but had lots of fun with it.
Four ERs, Type 3 UR (35) with pseudo cell, XY-Wing Chain (58-38-38-38-35) with pincer transport and BUG+2. |

I used a xy-wing 13-5 with pivot 13 in r2c4 and an extended pincer to delete 5 in r2c1 and solve the puzzle.
As a chain: (5=3)r2c3 - (3=1)r2c4 - (1=4)r6c4 - (4=7)r6c1 - (7=5)r8c1; r2c1<>5

Two steps:
| Code: | turbot fish/ER/Kite => [r2c6]<>3
<18> W-Wing => [r4c6]<>1
