If EJ72 is omitted then GNU Go must be taught to play the
shoulder hit. This leads to a complicated situation. I am
doubtful that this pattern should be removed.

Assuming that the fourth line stone is at the 4-4 point,
perhaps the solution is to omit the first one space jump
but to play a kakari on the other side. The original kakari
stone is light since the 3-3 point is still open.
