You can remove <6> from r8c8 which then allows basic moves to solve

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
