 Hi Alfred,in your last post (step #3), I can't catch how you get i8=7 in the branch f5=8 of your kraken cell (138)f5. Once you get g1=5, you get also h3=2, h5=1 which is in contradiction with h1=1.Best regards, cenoman 03/Mar/17 10:03 AM |  |
 Hi cenoman. After c9=1,UP32:For f5=8,c5=5,g5=3,g1=5=i9,g3=357 and becomes 7, and so does i8.It is true that h3 would become 2, but sometimes you have to wear blinkers, and just look at what you are intrested in, g3=7, in this case. Best Regards, Alfred. 03/Mar/17 6:14 PM |  |

The part of your English sentence, f5=8,c5=5=g1=i9, demonstrates -1i9 (i.e. your step #2); if you now use the More... 04/Mar/17 4:05 AM |  |
