Monkey jump is a big yose move

The Monkey Jump is a large knight's move from the second to the first line. Similar to that is the Knight's move to a, which makes a Small Monkey Jump.

It is normally a big endgame move: You use an open skirt to run under your opponent's group to reduce her potential territory.






Sente or Gote?

A monkey jump is proverbially worth 8 or 9 points in sente, although the exact amount depends on the position, and it may very well be gote.

In the diagram above, B1 is usually not sente, simply because White does not need to answer at all. It also seems that White can answer it in sente:

Ending in Gote

But Black can play better:

Later, White will probably get this exchange in sente. But this is still a gain for Black. See Value of a monkey jump for a detailed discussion.

If the marked stone is one line higher, as in this diagram, Black can keep sente with this simpler (and better) line, as White needs to defend the cutting point at a.
