Tanuki no hara tsuzumi

    Keywords: Tesuji

Chinese: 黄莺扑蝶 (huángyīng pū dié)
Japanese: タヌキ(狸)の腹鼓
Korean: -

One of these colorfully named tesujis, tanuki no hara tsuzumi is usually translated as the raccoon-dog drums his belly. The [ext] tanuki (Nyctereutes procyonoides) plays a part in Far Eastern mythology, a prankster and shape-shifter not unlike the fox, but less malevolent. Statues depicting the mythical form of the tanuki are often seen outside of temples and restaurants in Japan. Real tanuki resemble something of a cross between a raccoon and a fox.

The Chinese go term for the same tesuji (黄莺扑蝶) translates into English as the [ext] yellow oriole captures the butterfly.

This problem from Gokyo Shumyo illustrates the basic pattern.

Here B5 is the tesuji. Critically, the marked black stones have three liberties. Any fewer and the tesuji would not work. After B7, a and b are miai as are c and d. White can even capture the two stones on the edge, but will never get more than two liberties.

Knowledge of this tesuji is also a prerequisite for playing and responding to this hamete. Black must decide now between answering W1 at a or b. See 4463 enclosure second-line side attachment, trick play chapter.

Synonyms

Tanuki no hara tsuzumi is sometimes mistranslated as patting the raccoon's belly. A tanuki (raccoon-dog) is a canid, related to wolves and foxes; it is not a raccoon.
