Here are the weekly Go problems for week 71.
Black plays first in all problems and all solutions are labeled ‘correct’. Have fun!
Easy Go problem
Crouching down can be an effective move when it prepares you defend against multiple attacks.
Intermediate Go problem
Ideally, you’d like to defend by attacking, where you can. This sort of shape occurs fairly often in games.
Hard Go problem
It won’t take long to see where black can make an eye, but you can expect white to be uncooperative. The question is, what will you do then?

You can find Go books packed full of life and death problems, tesuji problems and other valuable Go knowledge at the Go Game Shop.

About David Ormerod
Nice and solvable problems for me
Thanks so much for the great problems. I especially liked the intermediate one.
In the intermediate problem, with C4 played at move 5, isn’t F2 correct at move 9?
As Vlad said below, playing F1 or F2 before exchanging B1 for C1 lets white leave some annoying ko aji in the corner by playing at B1 herself.
So you don’t want to let white play at B1 if you can avoid it.
If this wasn’t an issue, playing on the outside first would be better style. It’s just that black doesn’t have that luxury here.
N Good, it seems to me W can get a multi-step ko with F1.
Thanks David for the problems. The hard one is very useful in actual games I think.
for some reason I had MUCH more trouble with the int. than the hard. must be a blind spot
I love the squeeze tesuji.
This was the first time I solved all 3!
However, the hard one took me several tries before I realized I was going the wrong way.
