Oki Wants Ikken Tobi

    Keywords: Shape, Tactics

The name of this shape is a pun on Obi-Wan Kenobi. At the same time it indicates that, when a certain placement (oki) threatens, the following one point jump (ikken tobi) is called for. I discovered this line of play, after having it seen in Gokyo Shumyo, Section 1, Problem 18, Gokyo Shumyo, Section 1, Problem 34 and Gokyo Shumyo, Section 1, Problem 36. It is an example of How to learn from examples ? - a thread on rec.games.go started by Robert Jasiek. # : - 7

White can't connect at W5, because she is suffering from shortage of liberties.
