A Japanese term.
ハネ
A hane is a move which "reaches around" one or more of the opponent's stones. The basic shape is the one formed by White 1 in this diagram. It is the natural response to a contact play.
There are many positions where a hane is a good move, as is witnessed by proverbs like Hane at the head of two and There is death in the hane.
Bill Spight: About hane, reach around, wrap around and bend around: "Bend" could be confused with this play, a magari (turn). Better just say "hane".
