Ear-cleaning tesuji  

W1 is the ear-cleaning tesuji, forcing Black to protect with a, b, c, or d.

In Japanese, mimi-souji.

Examples from professional games

Here's a real-life example of the tesuji taken from the 2005 Meijin league:

Kobayashi Satoru (B) vs. Cho Sonjin (W)  

B1 is tesuji, Black uses it to help his weak group make shape while attacking White. Black goes on to win this game by resignation.

W2 could have resisted at a

Lee Sedol (B) vs. Tang Weixing (W)  

White played W1 but a was also an option.


Angle point  
  1. If you look at black+circle, black+square and white+circle, you see that white+circle sits on the 'angle'; even if Black plays the circled point, no eye here.
  2. This shape would therefore be better for Black with black+circle at a, weakening white+circle.
  3. This shape would be even better with black+square at a.
  4. In that case, we probably do have White b, Black c in the near future for a bamboo joint; but this is strong for Black, who can then move out easily in several directions.

Context is, as usual, important. Assume first White is attacking here. Then White's attempts to cut are irrelevant (won't happen any time soon) - but Black presumably must connect somehow. In that case the connection with black+circle is shapeless.

If on the other hand White is on the defensive you perhaps look longer at White's forcing plays. But then white+circle wouldn't be played this way, in most cases. White normally gets more by playing white+circle at black+square.
