Miniature Go Problem 1

Yi Ch'ang-ho - Rin Kaiho (3rd Tong Yang Securities Cup, Game Five, 27 January 1992, see both Go Invasion et Reduction, volume 2. and Tournament Go 1992 page 239.) Yi has just played the invasion at W1, and naturally, Black (Rin) pincers the invading stone at B2. Yi now plays the off-beat move W3, a tesuji.

Problems for discussion:

  1. What happens if White plays "the usual move", invading at a, instead?
  2. What happens if Black answers W3 by blocking at b?
  3. How should Black answer W3, and what will the continuation be?
An unusual invasion?
