Today #4 was the first time I got it quickly. I was very terrible the other days 
I think the hints have gotten better though, easier to utilise when they’re on the board and in the tree themselves, but I do also like the summary appearing below the board with the “too long!” type comments etc 
I do have an idea for a strategy that I might test tomorrow.
I do also wonder if someone only knows very few joseki, would it be a fun puzzle or very difficult.
