Tsumego From Games 44 / Attempts

Sub-page of TsumegoFromGames44

Tderz: alive as it stands? If white tries to kill s/he suffers mochikomi, on the other hand, if black tries to swallow and live too big, he might die in damezumari of a pseudo-seki [2]. Unimaginative endgame [1] can lead to 5 (up to possible 8) points difference with best play (diagrams [4], resp. [3]).

Best result?

[Diagram]

[4] Black net 1 point

Black has 2 points, White made 1, hence B+1 - W+1 = net 1 point for Black, hence 5 points better for White than [1].


Hence, White's oki-play seems to be a good endgame technique.


[Diagram]

[3] Best result? for White, worst for black (after death)

Is this the result? endgame? B+2 - W+4 , hence 8 points better for White than below [1].

[Diagram]

[2] "pseudo-seki"



attention! dead by "pseudo-seki"

[Diagram]

bad endgame




Yet, if white simply plays the unimaginative W1, black runs the same risk, when answering with the careless B2.



If now white a is answered by black b, everything reverts to dia. [2] above (death).

[Diagram]

bad endgame [1]



However this way, a and b are miai and black lives with 6 points.

Best result?

unkx80: Anything wrong with this?


[Diagram]

Seems like seki

ilan: Seems like White will have to make an inline 4 to atari Black, so this leads to seki.
