Does not look like a solution - are you sure it is supposed to be one? |

The first solution is a common net. After that move black cannot get out. As for the second solution, it doesn't seem to work. It may also be net, but looser and more complicated. As Kageyama teaches in Lessons in the Fundamentals of Go, if there are two options to capture your opponent's stones, always choose the firmer of the two. The first solution should always be played in this situation. Black 2 seems to be the move to get out. Without the marked black stone it doesn't work because of something like the cross-cut tesuji. Since that black stone is there, however, it does. White 3 doesn't seem to do anything to prevent black from connecting and it doesn't. Black 4 connects back to the marked stone. If the marked stone is not there here is how the solution works. If black cross-cuts white just captures the black cutting stones. If black tries to force his way out, white still captures the cutting stones. |

It does look more complicated to read. |

I don't think it works. I tried that and this is what I came up with for black. Black is out. EDIT: Bill's solution below is even better. Black is out and white is probably dead on both sides after those white stones die. However, the ladder must work for black. |
