3-3 point shoulder hit, tenuki variations

White's tenuki  

White may ignore in this position after the 3-3 point shoulder hit: White shouldn't play tenuki earlier, but Black has played on the second line and this could be a good moment. This plan was played a number of times by Go Seigen.

Black's normal plan  

Usually Black attacks with and . Then is the Go Seigen choice of haengma, treating the stones lightly (Black a, White b, Black c, White d can occur).

Hu-Yi  

This is from Hu Yaoyu-Yi Ch'ang-ho (B) 2003-01-22. After White is threatening to play at a. Black however plays tenuki; and after has created a strong group to minimise what White can do on the left.
