 SE=7.2 (beginner level puzzle)1. SST to UP282. (6=4)f8-(4=5)e9-e1=b1-(5=6)a2 > -6a8, SSTE// MWing(7.3)i48e8, -3e4 12/Aug/11 12:40 AM |  |
 1. Note eg9=45;hi2=48.Unique possibilities to 28.2. Whether f8=6;OR f8=4,e9=5=d2,a2=6;a8=1.UP29.3. If f3=4,f5=9=b6;row 6 is devoid of 1.So f8=4.UP58.4. Whether a6=5,i6=4;OR a4=5,hi4=37,h5=8,h2=4;h6=6.UP81. 12/Aug/11 12:42 AM |  |

 you must have missed NT(159)f45e6 in your SST after +1a8 Alfred - causes cascade of UPs. 12/Aug/11 12:58 AM |  |

 T-Ultralite 8.3 (SE @ 4 krakens, 11 chains) 000091405006000000010005083009000300020980007000300040060070030700204000001000500 12/Aug/11 3:44 AM |  |
 Thanks kobold.I missed the 19 pair at be6. My step 3 is then accounted for. 12/Aug/11 9:30 AM |  |
 Hi Kobold, In your solution for the site puzzle today, you used the abbreviation SSTE - could you please advise what this means - many thanks. 12/Aug/11 8:54 PM |  |
 Really easy today - UP to 81 in around 5 mins. 12/Aug/11 9:25 PM |  |
 Kobold, you are setting the bar too high for most of us I think. In the T-Lite, after UP32, d8=5 leads to a contradiction after umpteen UPs, and f9=5 reaches UP81. With the T-Ultralite, I couldn't make any progress at all. Neil, SSTE means "Standard Sudoku Techniques to the End" (UP81). 12/Aug/11 10:50 PM |  |
 SSTE means (S)imple (S)udoku (T)echniques to (E)nd".other than unique possibilities and naked/hidden sets and XW(ings), I list the patterns in order used (possible UPs, NP, etc. between patterns) after symbol // or inline /.Patterns I currently use in SST (always listed) are:FXW More... 12/Aug/11 11:54 PM |  |
 I didn't think the 'Lites' were too hard (short only aic). Naturally I reject puzzles with obvious cascades at start. 12/Aug/11 11:59 PM |  |

 - T-Ultralite surprises me Alfred, I almost rejected it because I felt you would find it too easy! 13/Aug/11 12:14 AM |  |
 BTW, method used to find chains is probably closely related to method Alfred uses. I examine eliminations that cause cascades or weaken the 'ice' and then try to prove the elimination with a chain and then try to translate that chain into a correctly written AIC. The use of patterns in AIC makes the problem interesting (like Hesse's "Glass Bead Game"). 13/Aug/11 12:41 AM |  |
