SER 9.0 for today's tough. IMO, today's puzzle difficulty is slightly overestimated by Sudoku Explainer. Nevertheless, I peaked into the future and could not resist analyzing a puzzle with such a lofty rating.

Since I went through that trouble, it seemed natural to create a blog page More...

A beautiful landscape plant. Like the irises planted against the same wall (yesterday's photo), also very easy to grow in dry soil. The leaves are very resinous and they smell like "Christmas" to me.

my go, w/o trying to simplify and before peeking at Steve's blog (agree 9.0 rating too high) UP=26

1.(5)c8=b8-(5=7)b5-(7=6)e5-(678=2)e9f78 => c8<>2 UP=33
2.(5)b5=h5-h12=(378)g2h12-(7)c2=c3-HP(29)c39=(9)c8-(5)c8=b8 loop
=> b16h4<>5 h39i1c3<>3 More...

typo in step 3. (looks simpler as kraken diagram)

3.Kraken Cell(178)g7 => g2<>7
(1)g7 -(126)gh3g1 = (7)gh3
(8)g7 -(489=5)cgh8 - (9)c8 = HP(29)c39 - (7)c3 = (7)gh3.

1.UP=26 w/o quads or other errors
2.(5)c8 = b8 - (5=7)b5 - (7=6)e5 - (678=2)e9f78 => c8<>2 UP=33
3.(5)b5 = h5 - (5=378)g2h12 - (7)c2 = c3 - HP(29)c39 = (9)c8 - (5)c8 = b8 loop
=> b16h4<>5 h39i1c3<>3 g1c8<>8
4.(5)b5 = b8 - (5=9)c8 - c3 = (9-8)b1 = (359)bfh1 => h5<>5 UP=38
5.UR(35)ah12 => a1=8 UP=81

in my first attempt, i mistakenly eliminated (8)c7 instead of (8)c8 from the loop - off course from there. the final solution uses no complicated steps and only 3 chains - max depth 5 for the loop. certainly not a 9.0 puzzle!

mea culpa: solution requires (uses) the kraken after the loop (too much rum last night).

my last entry here (promise) using only simple steps. UP=26
2.(5)c8 = b8 - (5=7)b5 - (7=6)e5 - (678=2)e9f78 => c8<>2 UP=33
3.(5)b5 = h5 - (5=378)g2h12 - (7)c2 = c3 - HP(29)c39 = (9)c8 - (5)c8 = b8 loop
=> b16h4<>5 h39i1c3<>3 g1c8<>8
4.(267=3)agh3 - More...

note: steps 6, 7 replace Steve's finned swordfish step; otherwise almost the same.
