Regular two-way logic works to prove r3c1 is white.
Use the two-way logic on the 1 in r5 (it can only be put in c1 or 2).
If it goes in c1, then r3 must be white (due to the 2 in c1).
If it goes in c2, then r3c2 must be white (due to the 2 in c2), which then makes r3c1 white (due to the 7 in r3).
Either way r3c1 must be white.
Then line logic to finish.
