HolIgor: Strange, though the marked stones are short of liberties, my understanding of damezumari is different. Damezumari is usually used to describe the positions in which one of the sides cannot make a usefull move because of the decrease of liberties.

I know some perfectly alive and healthy groups with 2 liberties only.
