 Hi Les. I can't follow your logic today. After b4=8, a3=8 and no contradiction yet? Best Regards, Alfred. 27/Feb/17 7:39 AM |  |

 Hi Alfred,Note: UP 32 as confirmed by Cenoman.If f6=8 then this leads to a3 and b3 both being 8. Therefore f6 cannot be 8. i.e. as stated ab3<>8.I found the puzzle falls out with UP's thereafter.Cheers Les. 27/Feb/17 11:12 AM |  |
