However, one fundamental weakness remained in force until today: The implications of the hanezeki are beyond the program's capabilities. This fact can be cushioned successfully by case-related modifications to the hanezeki, before the analysis starts.

Once the tail of the hanezeki has no more outside liberties (as here in the diagram at left, after the Crosscut Sequence, indicated with /), the program will often mistakenly continue with , both with White, and with Black.

In fact, a White move at loses about 20 points, and a Black move at does not rescue 20 stones, but means suicide.
In most of the tenuki paths after the guzumi, Black must find life in the upper right, so the hanezeki remains stable.

Here, the program can be helped by inserting a move sequence before the guzumi (with now), which turns the hanezeki into a real seki. The result is shown in the diagram at right (with White's three stones that are captured by already removed).
