Practical Endgame Test 8

  Difficulty: Advanced   Keywords: EndGame

Hi this is my first page here, so feel free to erase the odds... First it shows a problem and then the solution. Afterwards I have a question and I hope somebody can give me an answer.

What is the best sequence for Black (assume no captures, and Komi 0)[1]?

[Diagram]

9x9 yose problem


The solution is

9x9 Solution a)


[Diagram]

9x9 Solution b)


Note the sequence starting from 4 onwards is not unique.




Well, this is nice and Black wins the game. But now I have a question about this.

The question is: Is there a way to find this sequence without calculating "all" the possiblilities and corresponding outcomes?

I.e. how to order the possible moves by values?
(especially why to choose to first move, since its value seems to be 1 and the value of move 4 seems to be 2.)

I reckon the answer corresponds to MiaiValue, DeiriCounting and Tedomari. So probably Bill is the person to ask ,-), but of course everybody is welcome.

Bill: You do not have to read out the whole endgame to find the best play. This is a tedomari problem. Analysis on Endgame - How to find the move: Analysis
