(2=167)r7c3,r8c23 - (1=269)r8c7,r79c9 - (9=2)r4c9 => -2 r4c3 ; stte
Question on the fine points of notation. I don't think anyone will object to how I've written the chain above. However, how would it be if I had written:
(2=167)r7c3,r8c23 - (1=2)r8c7 - (2=269)r479c9 => -2 r4c3
Would that be considered kosher, given that the r479c9 set is already locked? (Yes, I know that it could also be written - (2=69)r79c9 - (9=2)r4c9. )
