(8=7)b8-b9=i9-(7=8)i5-a5=a13 > -8b12, STTE (FSF(6) etc.)

Hmm. clearly I must have missed a fish or two somewhere as I played basically the same opening move as Kobold!
However I had fun with a big 69 ADP ..

#0 SSTS, x-wing(3) ; UP33

#1 m-wing(78) extended ; (8=7)b7- b9=i9 - i5=(7-8)a5=c6 => c7<>8 ; UP45

#2 grouped More...

UK extreme this week

(2)b5=(28')b1a2-(7)a2=a4-h4=h5 > -2h5, UP34
(1)f6=i6-(1=67)h45-(36=1)dh9 > -1f9, UP81

there seemed to be cascade of finned swordfish after first chain FSF(6)bdi149 fin=i6 > -6gh4; then FSF(6)dgi269 or something... will recheck

My progress was slow as molasses. One chain took me to UP 43, but from that point on I needed several chains each eliminating only one or two candidates. No way I could (or would want to) reproduce that solution as a proof here. Tip my hat to those who did better.

Does everyone but me get the hard and tough puzzles on the first shot? I have to try harder I guess. I usually have to check my moves on these.

nice solution peterj.

I wish I could get some of these. They're so unusual. But no birds can be exported from Australia.

For those who don't follow Eureka:
1. Note ai5=78;e6/f4=23.Unique possibilities to 33.
2. Whether b8=8;OR b8=7,h8=6=i6,c6=8;c7=3.UP45.Note bd1=69.
3. If i6=6=g2=h8,c6=8;The 69 deadly pattern at b14/c4/d19/e5/f59 cannot be resolved.So i6=8.UP81.
