Bulky Seven

    Keywords: Life & Death, Shape
Bulky Seven  

Found in Lessons In The Fundamentals of Go written by Kageyama Toshiro.

"Even those who have heard of the bulky five have not heard of a bulky seven, but here it is, and White can kill it.

W1 strikes at the center of Black's shape, and Black is already dead. If he plays B2 at W3, he cannot do anything after White a. If White played W1 at W3, then B2 at W1, W3 at B2, Black a would mean a ko, and a white failure."


Note that this only works because the black group isn't solidly connected.

Also alive  
Shortage of liberties  

Note also the shortage of liberties that makes this work. If either of the white+square stones are missing, Black can capture the invading group and survive. If the white+circle stone is missing, Black can cut and break through to the outside.
