3-4 point Josekis

3-4 point  

This page is the start page for many 3-4 point joseki. For many centuries, the 3-4 point has been the most common way to start a game. Over the ages, many joseki have appeared for approaching the lone stone.

The 3-4 point aims at balancing territory and influence. It looks forward to local development to form a corner enclosure. See 3-4 approach, high or low for discussion regarding how to choose an approach move. The most common approach moves for White are:

• a The Low approach
• b The high approach
• c The distant Low approach
• d The distant high approach

Less common are e, f, g, and h. The approaches at x and y are commonly regarded as mistakes.

If Black has the next move in this corner, then Black can make a 3-4 point enclosure.

[edit]

Low approach (36%)

Before about 1970, the knight's move shown here was the standard way to approach a 3-4 point. White aims to challenge black's claim to the corner territory. The most common replies are pincers, often leading to complicated joseki. (See high vs low pincer for discussion on choosing which pincer to play.)

For an overview of variations, see 3-4 point low approach. For more detail on a specific move, click on the letter in the diagram.

Low approach  

at

• a diagonal very popular before komi
• b one-space low pincer classic, severe
• c one-space high pincer forceful
• d two-space low pincer classic
• e two-space high pincer dominant in middle of twentieth century
• f three-space low pincer
• g three-space high pincer
• h upper attachment.
• i side attachment.
• j keima - peaceful
• k two-space extension
• l shoulder hit, a quasi hamete but playable
• m not joseki, but sometimes played by beginners; see Noseki 5.
• t tenuki converts to 3-5 point low approach

High approach (45%)

The high approach to the 3-4 point is a modern tactic, aiming to build influence. For an overview of variations, see 3-4 point high approach. For more detail on a specific move, click on the letter in the diagram.

High approach  

at

• a inside contact most common of all joseki
• b outside contact
• c keima steady
• d low extension 1940's
• e large low extension
• f one-space low pincer
• g one-space high pincer
• h two-space high pincer
• i two-space low pincer. Rarely played; see missing pincer
• j three-space high pincer
• k rarely played; see Compromised diagonals and joseki 1
• l thrust, a Kitani Joseki
• m 3-4 point high approach, ogeima
• n not joseki; see 3-4 point high approach, kick
• t (Tenuki): transposes to 4-5 point 4-3 approach

Distant low approach (10%)

The distant approaches allow black to take the corner territory easily, but avoid the violent fighting that can result from a pincer against a closer approach. For a context where the distant approach is commonly used, see Kobayashi fuseki.

For an overview of variations, see 3-4 point distant low approach. For more detail on a specific move, click on the letter in the diagram.

distant low approach  

at

• a kosumi simple, territorial.
• b one-space low pincer influence
• c shoulder hit emphasizing the side
• d two-space high pincer
• e one-space high pincer
• t (Tenuki) 3-4 point distant low approach tenuki

Distant high approach (<5%)

For an overview of variations, see 3-4 point distant high approach. For more detail on a specific move, click on the letter in the diagram.

distant high approach  

at

• a corner keima
• b side keima?
• c pincer
• tenuki
• d outside contact
• e kosumi
• f shoulder hit?

Unusual approach moves (<2% each)

Unusual approach moves  

Approaches a-c are sometimes used against the Chinese fuseki, see 3-4 point approach from the wrong direction. The shoulder hit at e is not considered to be joseki. Click on the letters in the diagram for more information.

Enclosures (27%)

If white does not approach the corner, black will usually add a second stone to make an enclosure (but see Chinese fuseki). The most common enclosures are shown below; click on the letter for more details. For joseki arising from these positions, see 3-4 point enclosure joseki.

enclosures

• a Keima enclosure

• b Ogeima enclosure

• c High enclosure
  (10%)
• d Distant high enclosure
  (1.5%)
• e Keima along the side

Statistics

Source for all statistics on this page is the latest update of MasterGo, containing around 48.000 professional games until early 2009. The distance setting was invariably 4. Here only a sample from 1988 until now was used to give the modern preferences. More on the big historical changes in the next paragraph.

Historical Change

For a long time the one space low approach was the standard play; it was played in over 90% of the cases between 1900 and 1910. When players tried new ideas in the 30s, first the distant approach became popular, in the period from 1934 to 1937 it was played in nearly each third case. Later on, this move lost in popularity gradually and is rarely played today, although Go Seigen advocated it recently. The one space high approach - today's standard move, started to gain attention in the mid-twenties and got popular slowly but steadily, and only fifty years later it became more popular than the low approach.

Bob McGuigan: I'm not sure these simple statistics tell the whole story. It would be more interesting to see what happens in positions where both high and low approaches are appropriate. For example, the high approach is often more appropriate in moyo-oriented games, the low approach in territorial games. In other words, whether the high or low approach is played depends on the larger scale position, not just on the corner.

tapir: No, it does not, but it should raise awareness about historical change in joseki choice right from the beginning. (When you first come across a 3-4 point and wonder what you can do after that and look in SL for ideas that is. Leaving you with a less rigid concept of Joseki) Even if it does not tell the whole story it is based on a database research though. Another background for this statistics is to help players keep in mind that the low approach is still a move to consider. (I know a lot of players, who never play it.)
