Sudoku

You want my life going to pieces, don't you, Steve?

you can always chill out round here.

Actually rather pleased with one I just did. In a row were alternatives

39*
356789
56789
38*
37*
789*

(*) comply with the number of alternatives = number of squares rule (in this case four)

so it reduced to

39
56
56
38
37
789

and from this crack the dam burst and I finished it pretty quickly
