Small monkey jump

Small monkey jump  

For example here, played as an early endgame play, is a small monkey jump. It is more frequent in pro play in this particular corner formation than the ordinary monkey jump to a.

Theorists have worked on comparisons of the small monkey jump and monkey jump from the point of view of exact counting. In what could be termed typical positions, the small monkey jump doesn't gain an advantage in points.

Nevertheless it is played often in pro games, for reasons particular to the context.

Monkey jump need not be sente  

In this case might not be sente: the cut at c is usually worth a little more than five points (deiri), so that Black may not protect.

Small monkey jump follow-up  

Here if Black doesn't answer (at ), is a big endgame play.

May be this one is also possible and reduces the black territory a little bit more? Hans

Small monkey jump follow-up II  

If Black has a nearby stone on the left side (which is likely to be the case, since it is supposed to be black territory) this will take the corner.

If is impossible, Black can just block at a, and White will have to accept gote.

After seeing Bass's comment I think is not possible since White is simply dead. Maybe is only possible if is at b. Then Black cannot block at a. Hans
