Note, if you know or can invent the names of the tesuji, move diagrams to new pages. Uberdude: I'd say this is an example of shortage of liberties (Damezumari), though perhaps there is a more specific name for this type on the edge.

Sagari saves and kills

Imagist: What about "mineshaft tesuji" for this one? The area around 2 looks like a place where white can't follow because she'll fall down the mineshaft (maybe that's my overactive imagination).


Something from the endgame. Beginner's level.

Common with beginners.

The same tesuji

Jared Beck: The same tesuji, also common with beginners. I wish I still got to play simple tesuji like this. My opponents don't make such mistakes anymore!

Rather than calling this move a tesuji, however, I think makes more sense to call Black 2 "Anti-suji" This paradigm of learning the wrong move is more helpful to beginners than the paradigm of learning the response to the wrong move.

I borrow the term "Anti-suji" from Sakata Eio's book "Tesuji and Anti-suji of Go"

Bill: How about cut-back?


[Diagram]

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.

If you look at it this really is just a ladder that turns around a stone. You can call it a "Ladder" so it really isn't nameless. -Enz0

Bill: How about roll-up?


Driving tesuji

[Diagram]

Tesuji from joseki 1

Calvin: I found this in a haengma book, but it is also in joseki books. B1 is a tesuji with a double threat and in fact is the only joseki move in this position. Do you see it?

LukeNine45: This is very similar to the content at flying off orthogonally.

Tesuji in joseki (1)

tderz: If White continues with an understandable W2, then the following sequence B3-B7 is called the driving tesuji in English.

[Diagram]

Tesuji in joseki (2)

tderz: More often than not, White does not like above result and plays something like W2 to avoid the driving tesuji.

What is the Japanese name for the driving tesuji?

Tesuji from joseki 2

Calvin: B1 is a light way to play, which makes miai of a and b.

Both of these tesuji work by making the opponent choose between answering an attachment (which is usually good) or protecting or taking advantage of a move nearby. Either way, you get something. I find this idea rather interesting, but don't know what they are called.
tderz: That example is either in GalacticGo (Vol. 1) or in "Whole board Tesujis". I will check whether they gave it a name there.
