Hi i'm new to this forum and to sudoku. Im stuck on a puzzle and not sure on the best way to proceed. Any help on the techniques needed to finish solving this would be appreciated.
So far:
869|542|137
534|718|629
271|396|485
---------------
***|625|***
***|431|***
***|987|***
---------------
186|274|953
743|859|216
952|163|874
Candidates for middle 3 rows;
(43)(19)(78)***(73)(49)(18)
(6)(29)(578)***(57)(69)(28)
(346)(12)(5)***(35)(46)(12)
Hopefully that is quite clear. Im completely stuck, any ideas on what to do next will be appreciated
Thanks
