[Diagram]
Diag.: Monkey jump is a big yose move

Monkey jump reduces the potential territory of the opponent by large amount. The stone on the diagram cannot be cut off. if white has a large territory to the right she cannot ignore the move and has to reply.

The proverb states that a monkey jump is 8 points sente.

In some cases a small jump to 'a' is reasonable as well.



In the diagram above, black 1 is not sente. Does the proverb really say "8 points in sente"?

[Diagram]
Diag.: Monkey jump ending in gote.

Black can keep sente by not playing 5 but then white can capture 1 and 3 so this isn't 8 points for black.

Notice that if the marked white stone is one space higher...


[Diagram]
Diag.: Monkey jump ending in sente

This monkey jump is sente because W must now defend at A after black 5.

This is in response to Jonathan Cano's suggestions.

[Diagram]
Diag.: Monkey jump ending in sente.

I see in many Go books that they recommend this sequence (after white 4, black plays elsewhere).


[Diagram]
Diag.: Monkey jump ending in sente (follow up).

The follow-up moves can be considered as white 1, black 2. But how many points is it worth then? --unkx80

See Value of a monkey jump for an attempt to answer -- Andre Engels.



Is a monkey jump just another name for a large knight's jump, or does a monkey jump have to be a large knight's jump which invades the opponents corner territory?


Monkey jump is a large knight's move on the edge that can be connected to a stone on the second line. Other large knight's moves are not called monkey jump. The stone on the 2nd line has to be strong. e.g. monkey jump (black A) doesn't work here because of the weakness at B.

Jonathan states that the monkey jump is invalid, this I'll agree. But white's response is no good! In (continuation 1), black 3 can always play at 5 and black's loss is minimal compared to when black just plays at 5 alone (without playing the monkey jump at 1).

[Diagram]
Diag.: Monkey jump fails here (better version)

I propose this diagram. White really should play at 2. If black responds at 3, then the atart at 4 and the throw-in at 6 will capture all the black stones. Thus in response to white 2, black can only connect at 4, then white plays at 3, and you can see the difference yourself!
