Code:

Start at a and go to e. If you plug a 6 into r3c4 (a) and follow the letters that then puts a contradictory 6 into (e) at r2c6 which evicts the 6 at the start point (a).

So r3c4 (a) < > 6.

Eureka

6r3c4-(6=9)r6c4-r4c6=(9-6)r8c6=6r2c6-(6)r3c4
I, too, have about the same opinion as you. It doesn't have to be otherwise. Although opinions may differ after all. I recently did a paper on this, I found http://essaypapers.reviews/for it. Anything can happen in life and we can't influence some things. We can only adapt to them. This is my personal point of view.

thanks

A w-wing with 6s in column 5 removes 9s from r8c4 & r4c6
