3-3 point

The 3-3 point is a board intersection three lines from each of the two edges that form a corner. It is one of the standard points for opening in a corner. A stone played there immediately occupies the corner and can develop toward either side, but it exerts less influence toward the center than a stone on the fourth line.

Its main purpose is to secure or directly claim corner territory. It may be used as an opening move or as an invasion of a corner framework. Unlike the hoshi, which lies on the fourth line, the 3-3 point is one line closer to both adjacent edges and is consequently more territory-oriented. A 3-3 stone has less outward influence, so nearby approach moves, extensions, and corner enclosures must be considered.
