Unsettled groups with five empty points

A five stone "plus sign" (the X [[pentomino]]) and a "bulky five" (the P pentomino consisting of a square and one point off it, similar shape to a fist with the thumb extended") are the two unsettled ones. Playing in the point that touches the most others (four in the "plus sign" - center point, three in the "bulky five" - the one point in the square touching the outside point) will give the desired result to whoever does so.

Unsettled groups with six empty points
</div>

There are two unsettled six shapes, and the rest are all alive (see also miai).

One shape is the "rabbity six" — a square, plus adding the two points touching any one of the corners. (Similar to the plus sign five, but add any of the four taken corner points to get the unsettled six.) The opponent playing in the center point threatens to fill all but one spot with a bulky five shape, and there is no defense.

The other is the rectangular six ''in the corner''.<ref>[https://senseis.xmp.net/?RectangularSix rectangular six anywhere else] is alive.</ref> The opponent playing first in the top middle of the rectangle can kill the group. The defender playing first can save it by playing either there, or at the lower middle (denoted ''a'').

Any group surrounding more than six points is alive, but it may be necessary to respond correctly if the opponent attacks. Additionally, because of special properties of the corner, a group with more than six points might not be unconditionally alive, as it is possible for the opponent to make an eye or two within its territory.
