  HolIgor

[Diagram]
Diag.: 6 connects

This is a variation of squeeze tesuji but performed on the first line. As the result white is connected and black has to find life in unfriendly environment.


[Diagram]
Diag.: White to live.

dnerra: Here is a variant of this tesuji that I recently missed in one my games.

Answer to appear on a separate page?.


[Diagram]
Diag.: Sagari saves and kills


I'm adding one more here, as I don't know the name used in the English Go community. The Chinese call it "Da4 Tou2 Gui3" (literally translated as "big-headed ghost") --unkx80

Diag.: "Ta Tou Gui" Part 1

(Kris Rhodes: Pardon my interruption, but why wouldn't Black 1 at White 2 have worked to kill white? Or am I missing the point of the sequence?)

Answer It is a semiai. If black plays 1 ar 2 first then white kills two black stones faster. The tesuji is a clever way to win the capturing race. --HolIgor

Diag.: "Ta Tou Gui" Part 2

I believe I have seen this called the "stone monument tesuji" (the key moves being the descent to the first line followed by the throw-in). --DanSchmidt

This one is now copied on a separate page namely race to capture in the corner. I had forgotten it was already here until I stumbled on it while browsing recent changes junk. I have added that page because Sakata describes this tesuji as the "race to capture suji" in tesuji and anti-suji of go --Dieter

Bill Spight: Sakata doesn't really call this anything. In fact, "suji" can be plural (as with most Japanese nouns), and I think that is the case here. Sakata refers to 3 tesuji. First, the 2 step hane (B 1 in the Part One diagram), second the SuteIshi? suji (B 5 there), and third the HoriKomi? (B 1 in Part Two).

The name I have most often heard for this tesuji is simply "Two-stone corner squeeze". --Bass

dnerra: Someone I know likes to call this the "2-Dan-Tesuji". He says he has observed pretty consistently that 1-Dan's may miss this tesuji (in a game, not as a problem of course), while 2-Dan's usually get it right... I was 1-Dan when I first heard that from him, had recently missed it in a game, and decided never to miss it again :)



Something from the endgame. Beginner's level.

[Diagram]
Diag.: Common with beginners.


[Diagram]
Diag.: Another quite common situation.

This happens sometimes even at IGS 5k* level. But in most games it is never played and remains a hidden threat that limits opponent's freedom of choice.



I would call this ugly sagari tesuji. It appear with two unfriendly stones that cut off our forces and there is some shortage of liberties. The following diagram is just a general scheme. But the move is useful to remember.

Diag.: Ugly sagari


I have been wanting to find out the English (or Japanese written using the English alphabet, such as "tesuji") names of the following basic techniques, but so far I have been unsuccessful. Although they are similar, but the Chinese differentiate between them. They are "Bao4 Chi1" and "Men2 Chi1" respectively in Chinese.

Can anyone please help me? Thanks! --unkx80
