Another 1.33 [#1719]

88.160.4.234: Another 1.33 (2009-01-21 12:17) [#5683]

what about adding the following move to the list (occurs often in games) :

if i'm not wrong its value is 1.33 (with ko 1/3 approximation).

mmm... but i realize now that next move would also be 1.33 ? so it has a significant value only when black is komaster ?

I think it's a 2/3 ambiguous play.

If White plays first the count is 0.

We need to find the count of this position.

After the count is 2/3 (1 prisoner for Black and -1/3 for the ko).

After the count is 2. Since it's a gote the miai value is 2/3.

Back to this position. Since Black can make a 2/3 point move to get to count 2 the count in this diagram is 1 1/3. So the miai value of is also 2/3. It's ambiguous because the follow up move is of the same size. Similar to the following position

Fractic is right. :)

I also think that the anonymous writer has made a correct analysis, but is using deiri values (for gote).

I also think that this example, which is already on the page, is OK for this play. :)
