Niken Tobi
Two-space jump / Two-point jump
The niken tobi, or two-space jump, is a basic shape in Go used to develop quickly into the center or along the side (in the latter case it is usually called a niken biraki). It consists of two stones separated by two points horizontally or vertically.
In open positions or when supported by other stones, niken tobi allows a player to build influence or expand territory efficiently. It is frequently seen in the opening and midgame as part of frameworks or extensions.
Despite its vulnerabilities, the shape’s lightness often discourages a direct attack, and with proper reading, players can respond flexibly to cutting attempts. In tighter or more tactical positions, players may prefer stronger alternatives like the large knight’s move for added stability.
