Using the two point jump to sacrifice
The two point jump is often made with the intention of sacrificing a stone.
Example 1 (middlegame position)
, a one point jump is the basic move for defence. However, in this position it may be too heavy. White exchanges
for
and stays ahead of Black's stones with
and
, while these face white thickness below.
If we interchange
-
in the previous diagram: White not only cuts off a stone, but more importantly
and
are harmed by
and
.
Instead,
here will treat
lightly and suffice with reducing the size of White's framework. It is more difficult to attack this structure on a large scale. If White cuts off with
and
, the black stones are unharmed.
Example 2 (professional game)
This is from a game Lee Changho (white) vs Rin Kaiho, played on 27th January 1992. Black has just played
, and white wants to prevent black from capturing
on a large scale. Moving out with a would be too heavy.
This is the continuation. Later in the game black plays at a and captures
, but
and
are able to connect to safety, so white's aim is achieved.
Example 3 (bizarre shape in a pro game)
This is from a game between Hane Naoki (white) and Cho Chikun, played on 18th December 2006 (broadcast 18th February 2007).
White has just played
, and black needs to do something about white's central framework.
aims at the cutting point in white's shape. Playing
at a would lack fighting spirit, so white attacks on a large scale with
and
. Black makes a light and flexible shape. Later in the game
and
are captured, but white only gets a small territory in the centre, and black wins the game.

Example 4 (pincer joseki)
Here we see the two point jump at work again. Black's most common response to
is at
here, although any of a through d can be played (see 3-4 point low approach two-space high pincer two space jump). White should not be afraid of black cutting through the two point jump:
In this diagram,
is bad style, sometimes described as vulgar. White is happy to sacrifice
, in exchange for hurting
. (
is the simplest way to play, but
at a or at
is also possible.)
This is a better way to cut. White will probably continue at one of a, b or c, and black aims to play d soon. Again there is the possibility of an exchange (both
and
might end up captured), but this time with a result that is fair to both sides.
