Borrowing from
eleven's and
rjamil's marked cells...
Start a forcing chain from the one bivalue cell(a) and combine with Myth's
CoALS rule as applied to the two overlapping ALS(b):
(1|6)r7c5 - (16=39)r6c45,r9c4 => -39 r45c4; stte
[Added: The reverse chain leads to an obvious contradiction that still => -39 r45c4; stte. How does one
properly notate that?]
