(9)r3c5 = (9-7)r3c9 = r4c9 - (7=6)r4c3 - r3c3 = (6-9)r2c1 = (9)r1c1 => -9 r1c5

Wow, SpAce!
I didn't see that my chain can be simplified. Good work. I still need to work on my AIC's!

It was a lucky catch, but thanks. I just think it's interesting to try to view the same chain from multiple perspectives. Sometimes it leads to simpler solutions. There was nothing wrong with your chain in the first place. In fact, it was more interesting that way.

I'm sure we all do. You're obviously very skilled already, and your attitude indicates you're constantly finding ways to improve. That leads to good things. I also like it that you're pretty strict about the notations. Your chains and nets are not only correct but easy to read. One thing I might suggest for your diagrams is shifting your node indicators one place to the left -- that way the letters stand out more and the relevant nodes are easier to recognize, imho.
Code: Select all
`   *             |    |               |    |    *        *        |=()=|    /  _  \    |=()=|               *            *    |    |   |-=( )=-|   |    |      *     *                     \  ¯  /                   *    `

Hi, SpAce!
Thanks for your comment. It has motivated me to continue to work on my chains and nets. I always try to find chains only by myself, with small help from SudoCue 'Links' tool, and the solution grid that I copy into Notepad++.

I'll think about that. Good idea.
