2.00

[Diagram]
Defend two stones

[Diagram]
Capture two stones



[Diagram]
Take stone, save stone



[Diagram]
Crawling along width-two corridor

(Assumes an infinite White territory to the right.)

Ambiguous. Later, B5 - W6 is ambiguous (1.00).

2.08

[Diagram]
Take away territory



2.12

[Diagram]
Crawl on 2d line

Next play is worth 1.25.

2.33

[Diagram]
Take small corner



2.67

[Diagram]

[Diagram]

Even if Black is komaster, B2 is just as big, and takes sente.

Sente

[Diagram]
Take stone, points



3.00

[Diagram]
Defend three stones

[Diagram]
Capture three stones

[1]



[Diagram]
Connect with sente

B1 creates ko threats.


[Diagram]
Connect with sente (ii)

W2 is tesuji.

3.08

[Diagram]
Atari

Later, W4 - B5 is sente (1.58). Even later,


[Diagram]
Atari (ii)

so is W1 - B4 (1.00).



3.17

[Diagram]
Connect



3.46

[Diagram]
Connect

B a would be an overplay, because of damezumari. White replies at 1.



4.17

Reply to Monkey Jump

(Assumes infinite White territory to the right.)


[Diagram]
Continue from Monkey Jump

(Assumes infinite White territory to the right.)

HolIgor: requires verification.


[Diagram]
Capture one stone

Charles Assume that Black can't resist when White plays a, and Black must play b. Then the value is 4.5 if Black c will be sente later, or 5.5 if White at c hane-connect is sente later. That is, White gains four points anyway and takes away the circled points in the diagram above. The value is at least 4.5; if White also has c in sente to take away the square-marked points it is 5.5.

As Bill says, we tend to need the boundaries of territories to be marked.

HolIgor: I assumed

[Diagram]
Capture one stone

But in this case Black needs a to be protected. Charles Yes: so is B2 here tesuji in this case? White b, Black c creates shortage of liberties for Black.



5.42

[Diagram]
From value of a monkey jump

What it says there ... ?!
(Assumes infinite White territory to the right and sufficiently large Black territory to the left.)

B2 tenuki. Later W3 - B6 is sente (3.00).

[Diagram]
Crawl on second line

(Assumes infinite White territory to the right.)

Charles Bill, you edited this out - a problem ...?

Bill: The problem is that it is not correct play, given the conditions. The monkey jump is. Yes, if you play it, you pick up 3 points. But values are based upon correct play. You assume that your opponent's play is correct to obtain a value. Yours should be, too.

Charles OK - I think it would be useful either to have 'starred' status for something as conceptually basic as this one; or to include it in a footnote or other area. And to decide whether, for example, the comparison with the small monkey jump should be done on-list or off-list.

Discussion moved to Do Inferior Plays have Values.
