Sente Seki

White's turn  

Did Black omit te-ire? Solution.

Black's turn  

Solution.

Sente seki?  

Bill: makes seki with sente.

Ist das nicht eine Schnitzelbank? ^[1]

Gote seki?  

makes seki with gote.

Robert Pauli:

Well, it's always the case that if she has a this-kind seki, he has a that-kind seki after her move and vice versa, provided there is a next move.

The example isn't very good because

• the order is reversed,
• the back and forth only lasts for three moves, and
• it should be trimmed:

White's turn  

Anyway, what it tells us is that you have to qualify the term with who has the what-ever-kind seki. Implicitly, of course, that's the one to move. So, yes, the first diagram is a sente seki for Black, and, yes, the second diagram is a gote seki for White (as would be a third diagram).

 

White is urgent (otherwise Black plays at 3 [or any other there - RP] first and kills the whole lot). The marked White stones need to get two eyes (otherwise Black surrounds, kills; and then the marked Black stones are alive! i.e: not seki) - Mystery Go Player

Bill: Note on the diagrams. Stones that frame problems or examples, such as the marked stones, are conventionally considered to be alive. This convention spares the diagram maker from the tedium of providing two eyes for every group of stones and makes the diagrams look more natural. :)

unkx80: I tacked the diagram conventions to conventions in life and death. Some things just need to be made more explicit. =)
