Many moves have been analyzed in amazing depth. Some of this analysis is already to be found at Sensei's. This is no more than a list of the most basic moves, their shape-names (form) and typical usage (function). If it has a name know it. The stones don't really move. One should look at the relation between the new stone and a nearby stone already on the board. This old stone may be friendly or hostile. The names refer to these relations.
a: nobi / tsuke b: kosumi / kata-tsuki c: ikken tobi / - d: keima / keima approach e: niken tobi / - f: ogeima g: hazama tobi
How Moves Relate to Friendly Stones
Relations between two friendly stones that are even further away from each other do not have their own generic names, independent from board geography. In specific situations some do for instance extensions and opening formation?s. How Moves Relate to Hostile StonesIn order of Manhattan distance:
How Moves relate to Friendly and Hostile StonesThese are discussed at elementary moves 2. ElsewhereMoves in relation to one friendly stoneSolid[01] ノビ Nobi or stretch
A move in direct contact with a friendly stone. Typical use: Answering atari, tsuke, oshi, or making an iron pillar.
This is not a push.
One space[02] コスミ Kosumi
A move with two ways to directly get contact with a friendly stone. The two stones are on different lines. Typical use: connect, move out?, attack, answer to keima
Proverb: Answer keima with kosumi
[03] 一間ト ビ Ikken Tobi
The two stones are on the same horizontal or vertical line and have exactly one space between them.
Typical use:
Two spaces[04] ケイマ Keima
The two stones are on different lines and have two spaces between them.
Typical use:
[05] 二間 トビ Niken Tobi or Two space jump
The two stones are on the same horizontal or vertical line and have exactly two spaces between them.
Typical use:
Three spaces[06] 大ゲイマ Ogeima
[07] ハザマ トビ Hazama Tobi
Both oogeima and hazama tobi are at a distance of three spaces. Both need at least three moves to make a solid connection. There are four ways to do that with oogeima and even six with hazama tobi. However four of those six go over a. This makes a, the hazama (hole), a weak point. Oogeima does not have such a weak point. It is more solid. [1]; : Basically, distance is proportional to speed and inversely proportional to strength of connection -- JasonD See also haengma, for further development of these ideas. Moves in relation to enemy stonesMoves in relation to one enemy stone[11] ツケ Tsuke or contact play.
A move in direct contact with an enemy stone.
[12] 片ツキ Kata-tsuki or shoulder hit
A move in close diagonal contact with an enemy stone
[14] Keima approach, see Keima Kakari
A move in keima relation to an enemy stone
Moves close to both an enemy stone and a friendly stoneThese will be discussed at elementary moves 2. Moved from Messages. mAsterdam: I am hitting the wall of my ignorance in trying to make a shape-based catalog of basically generic moves/properties. Generic in the sense that there is basically no context?, so no defining direction, extension, shimari or kakari. Of course a property of a move can be that it occurs frequently in a specific context. One question I had (and answered my way - but maybe there are other considerations) is ''Where should elementary stop?" "Elementary" here should mean one stone in relation to one other. So I think elementary moves already contains moves it shouldn't: Push, bump, etc..., but that brings me to the next question. What to call the (class of) more complex moves? They are not really complex, just not elementary. I thought about "compound", because there are more relevant relations (at least three) but did not like that because it does not respect the notion that there is just one field of tensions defining the moves. Thoughts? Suggestions? Charles I think go encourages multiple approaches, and supports the idea that any one formal classification is too limited. "Take the cream from the top of the milk." mAsterdam: Heh. I could have said that myself. However, I find that I am still far from the limit of this formal classification. I could still continue with Type 1, Type 2 etc, like Richard Hunter in his classification of semeai in Richard Bozulich's second book of go. Ugly, but if I can't find a more meaningful set of names I will do just that. This is a copy of the living page "Elementary moves 1" at Sensei's Library. ![]() |
