White's tenuki  

It is known for White to play tenuki here, after the pincer black+circle. This example is of interest in relation with the discussion at quasi-pincer.

Black's plays  

Black's known plays next here are at a, which was seen often in the 1930s; at b (which White may ignore again, as in a game O Rissei-Hane Yasumasa (B) 2001-05-10), or at c (played by Goto Shungo).

Black's play at 'a'  

This is the most common (widest path) development: now White possibly plays tenuki once more.

The interest here is that this seems to connect with the Go Seigen 'twenty-first century' ideas. By transposition, this sort of local sequence is considered:

From enclosure  
From approach, W3 tenuki  

The latter occurred in Rui Naiwei-Yi Ch'ang-ho (B) 2000-09-08.

So, a tentative connection is established between three ideas:

  1. pincers called quasi-pincer because they don't set up a sector line to cross (failure to 'convex in' the opponent);
  2. pincers called quasi-gote because they are easy to tenuki (failure to have a telling follow-up)
  3. plays under suspicion of being submissive by Go Seigen's standards.
