is the one-point jump into the center, combining attack and defense. It gives White running room, while separating and placing pressure on Black stones on either side.
Common in running fights, the one-point jump moves out quickly (see getting ahead with a one-point jump), but is potentially vulnerable to being cut depending on the surrounding position (see cutting the one-point jump). It is also subject to the peeps at b.
According to the proverb, the one-point jump is never a bad move.
Some alternatives to the one-point jump for moving into the center:
- the stand at a, more solid but much slower
- the knight's move at c (see jumping out with the knight's move), which places more pressure on Black stones to either side, but is more vulnerable to being cut
- the two-point jump at d, which moves out even faster but is that much weaker. .
The term jump is reserved for moving towards the center. In other cases other vocabulary applies:
- along the side, one-space extension
- from the 3-4 point to the 5-4 point, small high enclosure
- towards the edge of the board, jumping down (tobi-ori?)
- when the jumping stone attaches to an enemy stone, jump attachment
