This was a BBDB for me - with one extreme fish/x-chain move - otherwise lots of turbots etc.
Code:
skyscraper(3) c26 ; r7c45<>3, r8c13<>3
m-wing(79) (7=9)r8c1 - r8c4=(9-7)r3c4=r1c4 ; r1c1<>7
sashimi-swordfish(3)r367/c489,r6c5=(3)r7c2 - r5c2=r4c3 ; r4c4<>3
kite(1) c4, r8 ; r4c7<>1
x-wing(1) r58 ; r5c89<>1
kite(8) c4, r6 ; r7c8<>8

This puzzle doesn't have any 3s in the givens. It still doesn't have any 3s resolved after basics.

Code:
 after basics

 |  379    6      3478   |  1389   34789  13     |  1378   5      2      |
 |  379    1      378    |  2      3789   5      |  378    6      4      |
 +-----------------------------------------------------------------------+
 # 70 eliminations remain

These eliminations are present for <3>,

Code:
 c26r5   Skyscraper                      <> 3    r7c45,r8c13
 r26\c58 finned  X-Wing                  <> 3    r3c8
   c2b9  Empty Rectangle                 <> 3    r5c7

These turbot-type steps are all that remain for Advanced steps.

Code:
 c67\r58 finned  X-Wing                  <> 1    r5c89
 r67\c58 finned  X-Wing                  <> 8    r89c5

... but this leaves the puzzle a long way from being solved.

Congratulations Peter on finding a solution for this puzzle!
