I think it should be changed, but probably not removed. This feels like a
case where gnugo is likely to play tenuki if left to its own devices. I
think the correct approach is probably to widen the pattern (eg a few rows
of ?s) so that it doesn't match when the X's are on the fourth line,
downgrade it to a j (or even t) pattern, and make sure there are patterns
suggesting other moves in the area (eg, attaching on top of the left X
stone). Also, the antisuji comment for this position should be removed
from hoshi_keima.sgf. While it's a bad move, I doubt it's that horrible,
and if gnugo played tenuki earlier, it might really be best. But
something should be changed about it.
