Several days ago I got the same results on guess 1, and I used STARE for my second guess. Today I decided to use a different word, and I thought CRATE would be a good choice, looking for a C instead of an S.
CRATE was a good choice. When the dust settled, the only solutions I could find were CACHE and CAUSE. I had a hunch that CACHE was the word of the day. But realistically, when I follow my hunches, I'm right only about half the time. Which means that my hunches are are really just arbitrary guesses.
