Very nice photo Kate

I have posted a "translation" of ttt's Eureka solution to the March 20 Tough on that puzzle's page. There certainly were some interesting things there. I have to confess that ttt just chides me for not learning/doing in Eureka :-).

Hi Brenda,
Thanks for your translating.
No, I dare not chide you . I only said: to improve your skills, you should follow Eureka/ AIC notation, it's quite clear to present complex moves (show relation between candidates & cells) and readers may be known your concept on viewing the puzzle then can apply them later for other puzzles.

~1 hour - lost time on a silly error and had to backtrack

Brilliant colours Kate

This is such a different flower! Thanks!

Oops - that was supposed to be a thumbs up...must be late!!!

1. Unique possibilities:h3=5,a2=9=g1,e1=2.Note pairs 17 at a46;23 at ch9.UP 27.
2. If h4=1,a4=7=i6,i4=3.If h4=2,b5=2,b6=4.In either case,i46=37;g8=7.UP 28.
3. When h9=3,c2=3,c5=6.Likewise,h9=2,h4=1=g7=e3,i3=6 makes c5=6.UPs to 35.
4. When c3=8,c6=5,c7=2=h9,h4=1=g7=e3.So ci3 are not 1,i3=6 More...

(about 20 min.) Maen! Wow, what a colorful flower!

Well I am working on it, I really am, but I'm kind of slow. But I do learn a lot from your solutions !!! Thanks for doing them.

Regards,
Brenda

A long path for this one;

1)Start at 23,basic techniques to UP=27
2)(24=7)i28-g8=g4-(7=1)a4-(1=2)h4,=>i4<>2
3)(37=4)i46-b6=(4-2)b5=b4-(2=1)h4-(1=7)a4 ,=>g4<>7.UP=28
4)(3)i4=(3-6)f4=b4-c5=(6-1)c3=(1-3)c2=(3-2)c9=h9-(2=1)h4-(1=7)a4,=>i4< ;>7.UP=33
5) More...

My path:
Start at 23 – given puzzle, UP27
01: (5)e46=(hp35-6)d6f4=(6)b4-(6=8)c5-(8=5)c6-(5)c8=(5)b7 => e7<>5
02: (5)b7=(5-9)f7=(9)e7-(9)e3=(9-7)d3=(7)b3-(7=3)b2 => b7<>3, UP81
