Done with greens, did anybody use more than one technique to solve this?

go

done

Difficulty score 64. No green, no guesses.

Ed, it's very rare that I don't use more than 1 technique. If you are referring to more than 1 advanced technique, I only used 1 advanced technique on this puzzle and then it all fell into place.

Advanced technique = Expert technique.

dng but did use a guess

My problem is, I always do these late at night, and if I get stuck I get too sleepy to be much good at it.
