x-wing(1)c49/r19 ; r1c18<>1, r9c158<>1

I will be in England next week. A country whose primary redeeming features are this discussion list and the quality of the Sudoku puzzles in their generally free daily newspapers.

On that site it was "tough" (and they get really tough!) - I guess it wouldn't register with SE.

Selective memory doesn't worry me... best to ignore the collateral damage of chains and use the outcomes that are helpful!

Anyway it was only a bit of fun - I think I initially had an l-wing and th ...

Seems pretty quiet on all Sudoku forums I frequent! Maybe people actually have a life and go on their boats/cottages/holidays in the summer - or maybe they only post when they get back to their office ...

This was a BBDB for me - with one extreme fish/x-chain move - otherwise lots of turbots etc.
