Force Feeding Problem

    Keywords: Problem

This problem is from the Force Feeding page. I'm editing this page to practice diagrams as well.

Black to play and live

I looked at this while I was eating, and it seemed to be a tougher problem than I thought. I was trying to read it out in my head, and it looks (to me) that Black can't live!

So I'm definitely missing a tesuji somewhere.


Here's what I have:

This leaves us with:

White's move

Now if Black takes at a, White b makes the eye false. If Black takes at b, it's a snapback.


Back to the original problem.

Black tenukies

If Black plays elsewhere, it looks like White 1 will capture the two marked stones and kill the group.


Am I on the right track? Can anyone give a hint? I didn't think seki was possible because the black group is cut in half. Is this an under-the-stone problem?

-- Chris Hayashida

UlrichGoertz: Yes, it's an UnderTheStones problem (pretty similar to UnderTheStonesExample2).

This way?

Confused: This might work.

Under the stones

W6 could also be at a or B7.

No chance left for white

Velobici: Its a beautiful problem. At first glance a just looks so right. Its easy at believe it works and quick reading can miss the white throw-in at the marked stone. Once one finds the under the stones tesuji, the throw-in reappears! Tempting one to believe that b is also a failure. If this problem is representative of Encyclopedia of Life and Death, then it is a wonderful CD.

Lynx: Dunno, the throw-in didn't seem that scary to me. ^^ :P
