Here are the weekly Go problems for week 80.
Black plays first in all problems and all solutions are labeled ‘correct’. Have fun!
Easy Go problem
With a little creativity (or experience), I’m sure you’ll be able to capture white’s big clump of stones.
Remember that it doesn’t matter if a few of your own stones are captured. Only the final outcome matters, so stay focused on your target.
Intermediate Go problem
If white’s cutting stones move out, there doesn’t seem to be much happiness in store for black. So..?
Hard Go problem
tl;dr – This is a classic Go problem that I like. The objective is to save both of both of black’s groups at the same time.
This famous problem has appeared in various incarnations, in classic Go problem collections like the Xuanxuan Qijing.
It’s one of my all time favorite problems, along with the ‘Monkey Magic’ problem from week 30.
It looks like two separate problems, but it’s actually just one. Your mission, should you choose to accept it, is to save both of black’s weak groups simultaneously (though you can start by analyzing them individually to make it easier).
While it might look like Mission Impossible, the problem isn’t actually as hard as it looks, so don’t be intimidated by it.
As long as you’re familiar with all the relevant techniques and tesuji, you can combine all of them to reveal the whole picture.
There are two different ideas for the first move, which will both succeed.
Have fun, and let me know how you go!
