Hi shoeless,

L.C. with number 3 in r23c1 and -3 in r2c3,r3c2
Naked Pairs 4,7 in r2c37
then
A.I.C. in r5c1,
if r5c1=9 then r1c6=9 and no number 9 in r6, so r5c1=4.

Ciao Gianni

Hi shoeless,

A.I.C. in r3c5,
if r3c5=7 then r5c5=9 r4c6=1 r4c7=4 r3c7=1 r3c2=7 and too many 7 in row 3
so r3c5=9

Thanks, that broke it free alright. Out of curiosity, how did you see that? Is there some sort of dependency pattern that you recognized?

Thanks again.

No, no one pattern.
It's routine or experience or ...
The number 9 is present only twice in the sector, row and column and I look at it for a color or other possibilities.
Sometimes it helps other times not.
