❤ PUZZLES: A tsumego a day keeps the doctor away

I don’t know.

It was more than two years ago:

Tell me more about that book. In English? Digital or paper? Editor?

In a real game there are also no captions that say White kills black. :grin:
Just the last few days I have been thinking about this. Maybe tsumego’s should be without captions.
About that specific puzzle: feel free to post it here and start a discussion.

I found the encyclopedia here on OGS as a puzzle collection.

According to Sensei’s library, it’s a software for DOS:

Here you can find a PDF collection.

From PDF’s preface:
“The problems come without solutions for two reasons: first, one can learn more by reading out all the paths and solving the problems oneself; second, the solutions are copyrighted.”

So probably the original version has solutions too.

Okay, while checking puzzles yesterdayI found these beauties.
And since I know you are art lovers, I share them with you.
Don’t forget to solve them.

White to move. Are the 10 stones on the left dead, alive or a seki?

Here are some other interesting tsumego threads:

Spoiler

I don’t understand B15.
The first move is sente because black responds with B15.
But
if the reward is a ko for life to save ten stones, probably it would be better to lose few points on the side and secure the big group.

Is white A13 so dangerous?

B15 avoid that w get a second eye. So b intention is bigger as just securing his group by avoiding the ko.

White can live with B15… I got stumped on this variation. Ko always depends on threats but white has a bigger group so it’s something that black can play.

My first thought was: “if white just simply captures, how could black kill? How could black prevent that white makes an eye in the corner?”
It took me a while to see how. :grin:

Surprise. Yesterday radio silence. No response, no discussions, no likes.
Assuming that you are still there, here are three new problems.
Of course you will have to solve yesterday’s puzzles first, before you can start today’s puzzles :crazy_face:

Neat, I just had a variation of that 2nd problem today: https://www.101weiqi.com/q/57717/

Hard problem when one of the variation is 3d level.

I find it incredible hard to rate a problem. I give it a rating and hope I am not too optimistic (or pessimistic). But I wouldn’t be surprised if I was way off many times. :frowning:
Unfortunately this is the best I can do.

yesterday's problem

I disagree with B18 as first move.
White can respond B19 and black dies.
Forcing move for black is B19.
White can’t play B18 because black A18 captures three stones and lives.
So white connects at C19, black atari B18, white connects E19.

Now black wouldn’t play A16.
Miai is cool, but connecting suddenly C14 black is alive and makes more points.

You can discuss it with the …
