Triple hane

In Dramatic Moments on the Go Board, Abe Yoshiteru recommends trying out a triple hane, as shown below, in certain situations, because it is full of fighting spirit, or kiai. Obviously, Black can get a double atari at the point a, so to play this way, White must be prepared to treat these stones lightly. Black can get a ponnuki out of this, so one shouldn't play this unless Black is already strong in the vicinity.

Triple Hane: Madness? Maybe not.  

If Black plays the double atari, White will typically connect and become stronger by sacrificing one stone, and if Black captures, White may be able to cut at b, depending on the situation.:
