    Keywords: Go term

Karui is the Japanese adjective usually translated in English as light. As in 'light play', 'light shape'.

Light play is:

  1. Probably unnatural for almost everyone, initially;
  2. Hard to learn until you are convinced it is necessary;[1]
  3. Immensely important in fighting.

Therefore understanding it ought to be a long run objective for anyone who wants to become strong.

The most basic point is quite simple: don't connect two stones solidly until you are confident that you won't want to sacrifice just one of them. Unfortunately this is hard to put into practice ...

A light shape is a shape that is not solid or strong, but cannot easily be attacked because one is able to sacrifice a part of it, thus using the opponent's attack to strengthen oneself. Apart from the willingness to sacrifice, there should also be an element of flexibility - depending on where the opponent attacks, either one part gets sacrificed and the other strengthened, or the other way around.

A light stone is one that is easily sacrificed, because the opponent will not have gained much when he captures it. This is for example the case if the opponent has already answered the stone - if he next captures it, it means he has answered the stone two or three times. To try to save a stone that is light, is a heavy way of playing.



Sabaki is a generic name for some techniques required for high-level light play - but doesn't mean light play (as often asserted).

The opposite of light play is heavy play.

The concept of playing lightly is usually talked about in terms of defence. It also matters when you are attacking, though: because the attacker should be flexible and (in general) avoid over-commitment, as well. See for example the two different kinds of example cited at screening kikashi.

Tamsin Just a quick thought here: I was studying a game of O Rissei's in which he played in his opponent's sphere of influence, surprisingly close to his thickness. O made several moves, but not a single solid connection. It's not very profitable to capture a single stone in gote, but neither is it easy to attack numerous stones that are only loosely connected.

Bill: IMO, light play is not particularly hard to learn. The main bar is psychological. It can be hard to do. Attitude is important.
