I really enjoyed this one.

Quote:
Fin Transport (Kraken?); r56c7<>3
XY-Wing (563); r9c4<>3
Potential DP (78), boxes 46; common outcome r56c8=72
W-Wing (35); r9c6<>3

Another similar move to Marty's first move (I'm guessing a Kraken x-wing(3) c2, c4, (3)r9c4?) with essentially the same solution path is..
Quote:
Aic with xy-wing ; (3)r9c8=r456c8 - r5c7=xywing(56-3)r5c7[(3)r5c4=(3)r9c7] ; r9c4<>3
w-wing(35) ; (3=5)r2c6 - r5c6=r5c7 - (5=3)r9c7 ; r9c6<>3
