Steve,
Very nice piece of work.
Ngisa,
Could you explain the part of the notation hat's highlighted in red? I'm confused, as I often am.

UR(14)r13c67=(12)r3c7-(2=1)r3c7-(1=9)-(9=5)r2c9-(5=1)r8c9-(1=5)r9c7-(5=8)r9c23(8=9)-(9=4)r4c1-r4c2=(4)r3c2 => -2r3c2

The UR14 removes 4 in r3c7 leaving the cell with 12. The chain leading to the elimination in r3c2 starts with (2=1)r3c7.Marty R. wrote:Steve,

OK, thanks. I have other thoughts and comments, but don't want to get into a long, drawn-out discussion. at least I now understand your solution.
