 one even a lowly mortal can solve:1. basic techniques to UP=47 note UR(27)ac27 = c7<>7.2. (7)g6=(7)b6-(7)a5=(7)a7 => g7<>7 UP=523. (3)g2=(3)i3-(3=1)i4-(1)g4=(1)g8 => g8<>3 UP=81. 12/Jun/10 12:28 AM |  |
 Wait on using the UR: 1. Basic techniques to UP =452. (7): b9 = b6 - a5 = i5 => i9 <> 7 ; UP = 493. UR(27)ac27 => c7 <> 2, 7 ; UP = 81 12/Jun/10 12:56 AM |  |
 Geez, Shiela ... you sound like Meg Ryan in When Harry Met Sally ... 12/Jun/10 12:57 AM |  |
 1. Note pair 27 at ac2. Unique possibilities to 44.2. Whether b3=5; OR b3=1,f3=3 (to avoid the 56 unresolvable rectangle at cf13),i3=5; a5=5.UP48.3. e7=2 (to avoid the 45 UR at gh67). UP81. 12/Jun/10 12:57 AM |  |

 yep, a fairly easy one today. 12/Jun/10 3:42 AM |  |

 A one-step proof that uses the UR right off (excuse the funky if-then formulation) If c4=4, then c8=1 {avoiding a2c2a7c7=27}, b4=4, b9=7, g7=7, with no 7 in row 6. Therefore b4=4, UP81 12/Jun/10 10:16 AM |  |

 Hi Rich. Nice exploitation of the UR to get it down to one step. (BTW, typo in middle of first line; b4 becomes 2,{not b2=4}.)Regards, Alfred. 12/Jun/10 5:53 PM |  |
 My typo too;should read {not b4=4} above. 12/Jun/10 5:55 PM |  |
