lcls to 27
1. Kraken column (3)a468 =>-3e3; basics to 29
||(3-2)a4=a8-(2=3)d8-d6=(3)e456
||(3)a6-d6=(3)e456
||(3)a8-f8=f13
2. (5)b6=a6-(56=4)a39-(4135=2)df8.ef9-d7=c7-(2=9)c5 =>-9b6
3. (3)i1=(38-9)i46=i78-g7=(9-3)g3=(3)f3 =>-3ef1; basics to 81

Hi Cenoman
I posted a reply to your post on 7 July 2017 tough. I vote now for 'singles' but will continue with VHBC. I hope you don't feel 'Trumped'.
Cheers Les.

Hi cenoman, you were right yesterday. That step 3 was invalid.

Best Regards, Alfred.

Wish I was as able as you 4 to solve these. I manage to finish, but it's a struggle.

similar to cenoman w/o kraken.
#1 X-chain (3)gi1=g3-g5=turbot(3)be5.bde7[e5=b5-b7=de7]-f8=f13 -> -3de1
#2 (3)e467=d6'-(3=2)d8-a8=a8-(3)a46'=a8-f8=f13 -> -3e3; singles to 29.
#3 (5)b6=HP(56)a36-(56=4)a9-e9=HQ(1459)eghi7-(159=2)c7-(2=9)c5 -> -9b6.
#4 (3=2)f3=-(2=9)h3-h6=(HP(89)-3)i46=i1 -> -3f1; singles to 81.
