4. (2)i2=c2-(2=3)c3-c9=(3)i9 =>i9<>2

Hi Alfred. I think it should be UP 30 only. I question ahi8=138 and therefore a48=38.
11/Jan/13 12:25 PM

Hi Les, def8<>138, and also g8<>138, so what is left in row 8, ahi8=138.
Best Regards, Alfred.

Hi Alfred. Please note h6=3(given)=>h8<>3=>ahi8<>138.Or is something wrong with my logic.

Hi Alfred. I understood ahi8=138 meant that a8 or h8 or i8 could equal 1,3or8. Is this not the case? Happy New Year Les

Hi again Les, it is true that h8<>3,(h8=18), but considered as a group, only 1,3, and 8 can occupy the 3 cells, ahi8, and this helps you to reach UP33.
Best Regards, Alfred.

Equivalent to Cenoman's ...

#1. Locked Subsets and Locked candidates; UP32
#2. Chain[4] : (4=6)a1-(6=7)h1-(7=24)hi3 :=> -4ac3.i1
#3. Chain[8] : Kraken Cell i9=2347 -> 3c3=3i9=8c9 :=> a8=3; UP81
