maen all! nice cruising place...looks like the wind whips it up pretty good being so open though.

25:55, hi all. It does get very, very cold on Lake Jindabyne, it's not far from the snow in winter and has claimed a couple of lives in the past - a swimmer died in the lake as recently as 10 months ago.

1)Start at 23,basic techniques to UP=31
2)(7):d5=d2-e3=g3,=>g5<>7
3)(2)d1=e3-g3=(2-1)g7=g5-b5=(1-5)b3=(5)b1,=>d1<> 5.UP=33
4)Loop:(5)b1=(5-1)b3=b5-g5=(1-2)g7=g3-(2=7)e3-(7=9)d2-df1=(9)b1,
=>b1=59,b3=15,ai5<& gt;1,g7=12,f2<>9
5)Kraken More...

a really complicated solution:

1. UP=32
2. (5)b1=(5-1)b3=(1)b5-(1)g5*=(18|2)i7-(2)i1=(2)d1. => d1<>5 UP=34.
*(1)g7-(1)i7 & (1)g7-(2=138)h8gh7-(8)i7.
3.loop (7):g3=e3-d2*=(98|4)b2-(4|61)a3=**(1)i6-(1=678)g459. => g7<>8, bc3a2<>4, i5<>1 More...

...have to find a way to clean up that notation, doesn't seem to directly translate into Krakanese as the chains are simply slotting in the derived links wherever needed (not stand-alone).

(5)b1=(5-1)b3=(1)b5-(1)g5=A(18:2)i7-(2)i1=(2)d1.
A:(2)i7
||
(1)i7-(1)g7
||
(8)i7-(138=2)h8gh7-( 1)g7.
10/Jun/10 10:03 AM
4.(1)i2=h2-h8=d8-(2)d8=B(67:1)g5. => i56g7<>1.
B:(1)g5
||
(7)g5-(137)d578
||
(6)g5-(6)i45=(*268)i127-(*17)hi2=(7)d2-(137)d578
10/Jun/10 10:11 AM
3.loop (7)g3=e3-d2=C(89:4)b2-D(4:16)a3=(1)i6-(1=678)g459.
C:(4)b2
||
(9)b2-(9)d2

(8)b2-(8=2)b9-e9=e 3-(2=9)d1-d2.
D:(4)a3

(1)a3-(1)a6

(6)a3-(6=4)c3-c6=a6-(1)a6.

Hm,,, I was sorry I hadn't timed it since this puzzle just zipped right along for me, click click click and it was solved.

snow is falling for the start of the ski season this weekend ... lots of cars travelling along Lake Jindabyne early Saturday morning...

My go for today (forcing chains, not forbidding chains);
1) Basic techniques to UP=32.
2) (2=7)g3=>g5=1,UP=81.
2a)(2-7)g3=(7-1)h2=i2-i456=(1)g5.
||
2b)(7-2)g3=(2)i1-i7=(2-1)g7=(1)g5.
Best regards, Neil

Hi Neil. After 7 at g3,g5 becomes 1 with a short chain; but 2 at g3 actually creates a 1 at g7 after a very long chain.
Like that other time you had a short solution to an unyielding puzzle, be nice if it was that easy, (compare with cold fusion).

Regards, Alfred.

Alfred,

Thanks. You are quite correct - my logic is flawed.

Best regards, Neil
