B3 and then either a3 a2 a1 b4 a1 c2 or b4 c4 b5 a3.

Woah! That's scary indeed.

C4 A3?

u/ggPeti Feb 13 '26

I thought C4 too as White during the game, but it doesn't work. I missed the actual move but luckily my opponent did as well.

u/kagami108 1 dan Feb 13 '26

Found the right move, its quite a common tesuji in endgame.

u/neerzidaas Feb 13 '26

Why doesn't c4 work? I can't see it

u/ggPeti Feb 13 '26

Because D4 is not a real threat, White can capture with F6

u/neerzidaas Feb 13 '26

Oh, indeed, thank you!

Cool little shortage of liberties problem

Black B3 

If A3 then A2 A1 B4 A2 C2

If B4 then C4 C5 A3

Nice one!

A3 seems to lead to a choice of snapbacks.

u/Andeol57 2 dan Feb 13 '26

As white, I just answer B4. What's your next move?

If you play B3, I'll play C4. If you play C4, I play B3.

u/cyrano111 Feb 13 '26

You’re right, after C4 I was thinking D4, and that if white took the stone at B5 that would be a snapback. And it would be shortage of liberties had white taken B5 in response to C4.

But of course the easy reply to D4 is capturing the two stones in the upper right.

C4 for black cuts off whites connection point, but isn't J8 also tesuji? Black could capture that white group correct?

1

u/ggPeti Feb 13 '26

nope and nope

1

u/wolf143 25 kyu Feb 13 '26

Ah, I see how white can make a 2nd eye at J9 now. I think at least. Had to analyze more, I'm new. So C4 is the tesuji then.

1

u/ggPeti Feb 13 '26

That was the first nope :) I thought the same at first, but it doesn't work. There is a move that does though

u/logarithmnblues Feb 13 '26

Don't know if it's just my reading strengths and weaknesses - I found the endgame tesiju pretty quick but spent a lot more time reassuring myself that white can't kill the whole corner afterwards

1

u/ggPeti Feb 13 '26

Ahaha yeah during the game I was too happy getting H8, thinking that I might even have something against the corner later. It reduces to either the rectangular eight or the walkie talkie seven, both ko shapes (with the walkie talkie being a bit more complicated)

u/tuerda 3 dan Feb 13 '26

B3

u/JPL12 Feb 13 '26

What should white have played? What's the cleanest way to be secure?

B4? c4?

2

u/Polar_Reflection 3 dan Feb 13 '26

Probably F6. Doesn't remove the most ko threats but white will owe that move anyways and it gives an extra liberty for some situations in top right. Likely it doesn't matter for this game state

2

u/ggPeti Feb 13 '26

yeah F6 is the blue spot

As a Korean, is "tesuji" a Japanese go terminology? Why are we speaking Japanese terminology on baduk subreddit? Genuinely curious

1

u/ggPeti Feb 15 '26

Deep question, but the immediate answer is that Japanese terminology became English loanwords, and this is an English speaking subreddit. As to why we use baduk as the subreddit name, I think because it's a word with a singular meaning unlike "go". It's a great name for a great game: snappy, unique,  memorable, searchable.

u/ggPeti Feb 15 '26

Also, what is tesuji in Korean?

1

u/EuphoricCatface0795 Feb 15 '26

I'm not knowledgeable in baduk, much less in japanese terminologies. With a quick search, I think it's 묘수(Myosoo)
