Thanks! Yours as well. Took me a while to see how the second strong link worked, and I liked it!
but I don't see -2 r1c4. Also, why the braces?
The subchain (2r1c9==2r5c3) supposedly kills 2r1c4, and the braces around the elimination(s) and the extra endpoint 2r1c9 were meant to depict that. Obviously they did a poor job; sorry about that! I didn't want to ruin the chain with elaborate subchain markings since those weren't essential eliminations anyway. Also, it seems that I braced the r3c7 unnecessarily as it's eliminated by the normal endpoints too (like r9c9). Should have been just {r1c4}. I could have left it out as well, but it was kind of fun to get so many eliminations at once without a loop.

How do you get -2r8c2 with those endpoints? As far as I see, only the 2r8c7 has a line of sight to it.
