Thanks to Clement for showing me that this was a multi stepper!
Step 1: remove <24> from r1c5 (also observe that if y=5 then cxx is a <24> triple)

Or you could have if b=2, c=4, d=6, e=8, r2c7=2, r2c3=4, c=2
So b=1 to solve
Or this is an XY chain 24-46-68-28 with pincers on <2> in c and r2c7 giving -2 in r2c3 |

Thanks, I was not sure about the UR but I did know that r9c5 <> 3
If r9c5=3, <89> pair in r7c56 gives a=6 and d=4 when either a or d must be <9> |

Also deadly pattern in r257c56 of <47> <79> <89> is avoided by -3 in r9c5 so r9c9 = 3 to solve
(this works but not sure of the logic now!) |

Looking again at my grid, whatever you put in d <249> still shows that a cannot be <9> |

Thanks for the notation Mogulmeister, I struggle with eureka, but if you describe something I know then this helps a lot!
Interestingly, you can put any value in r5c3 containing <148> because ... |

My first step was the same as Gianni's
Then the X Wing on <8> in r67c35 was too easy to ignore -8 r4c5 (and others)
Leads to XY wing 34-2 pivot r3c5 gives -2 r4c9 to solve |
