I agree with all these comments.

GNU Go makes many bad tenukis. This results in inconsistent play,
where a group will be developed, then abandoned because when a
threatening move is made, suddenly something else looks bigger.
strategy test 20 is a case in point.

I don't think these patterns should be changed from J to j.
Maybe strategy test 20 is a case worth thinking about. How
can GNU Go see that the connection at Q11 is absolutely
necessary?
