 A lot of movement in something that stands so still. Thanks for sharing, Robin. 19/Nov/10 12:08 AM 1) SST to UP=28.2) (5)a7=(5-6)h7=(6-1)h9=(1-4)h1=HP(34)D19-(3)d3=a3 => a3<>5; UP=30.3) xywing (3=7)e1-(7=134)afi3 => a1<>3;up=81. 19/Nov/10 12:41 AM Beautiful - and exquisitely sad. (At least what I see in it.) 19/Nov/10 12:44 AM OK, I give. Whatizzit? 19/Nov/10 1:28 AM SE=7.3 19/Nov/10 1:48 AM Pretty easy one today! Interesting sculpture! First impression was a bit of an Easter Island face! 19/Nov/10 2:06 AM 1. Note pairs 56 at ah7;37 at e19.Unique possibilities to 28.2. If i3=4=d1,d2=2,f3=7,f8=9,(pair 56 at c29);the 58 rectangle at af45 cannot be resolved.So i3=1.UP81. 19/Nov/10 2:42 AM Jiminoregon:The end of step 2 is not so clear,need to wright:2)(5)a7=(5-6)h7=(6-1)h9=(1-4)h1=d1-(34=5)d93,=>a3<>5 19/Nov/10 2:51 AM Does it have a tail? 19/Nov/10 3:08 AM farpointer: Have a look at Eureka. 19/Nov/10 3:15 AM also one step w/o AUR(5=6)a7-c9=(6-1)h9=i9-(1=4)i3-f3=(*245)d123-(3)d3=a3 => a3=3, STE 19/Nov/10 3:29 AM clearer is a3<>15 for my chain 19/Nov/10 3:30 AM sotir:thanks for the citation. I'd post on that site, but the notation seems clumsy to my eyes. The algebraic style (ala chess notation) here is saner. 19/Nov/10 3:40 AM sotir, I think that my step 2 was correct. The implication is either a7==5 or, if it is not, then a3==3. In either case, a3<>5. What is the problem as you see it? 19/Nov/10 4:35 AM My step 2 needs fixing up:2. If g1=4; e4=4.Also,d1=4,f3=7,f8=9,e1=3=a3,a5=6 (to avoid the 58 UR),e6=6 makes e4=4.UP81. 19/Nov/10 7:12 AM note: if you want a challenge, try May 22, 2008 tough; SE=8.5 - justed posted efficient (2 chains + 1 kraken) solutuion. 19/Nov/10 8:07 AM Must be my eyes - I see a cockroach belly!! 19/Nov/10 2:41 PM Yuck Midge!! 19/Nov/10 3:09 PM Actually probably more like dung beetles but I might be upsetting some people with this comment - art certainly is in the eye of the beholder!! 19/Nov/10 3:58 PM This took me a bit longer than it should have - 20:48. 19/Nov/10 6:06 PM Thought it was a frog face, but can see Plum's sad face and the cockroach belly hehe! Eye of the beholder. 19/Nov/10 6:52 PM Or should that be boulder? 19/Nov/10 7:05 PM 18:12 19/Nov/10 7:22 PM So breakfast Ma'am? 19/Nov/10 8:37 PM 23:05 27/Dec/10 2:49 AM
