In fact, this proverb should probably read

Knight's move to a capping play when on the third line

Third line

[Diagram]
Diag.: Capping play and knight's move

Why this knight's move ? Probably because it is a double purpose move. Its first purpose is to make territory while connecting, ...

Diag.: Capping play and knight's move

... and its second to prepare an attack like in this diagram. For comparison ...

Diag.: Capping play and knight's move

If Black defends and connects at 2, he has no severe follow up so that White can ignore it and treat 1 as a forcing move.



Fourth line

Diag.: Capping play against the fourth line

This situation yields quite a different shape. In this case, an extension to 2 is better. It prepares an attack at 4.

Diag.: Capping play against the fourth line

Because the stones are one line higher, the keima has a weakness and does not cooperate too well with the follow up at 4.



I open up this proverb page as food for discussion. I have far from the theoretical background to back up these ideas but I do have the advice from Guo Juan and indeed experienced the strengths and weaknesses of the shapes discussed.

(later) I now realize that the answer may depend more of the surrounding stones than the line of the capped stone. See tower peep.

Could these two proverbs summarized as:

Reply to a capping play with a one space jump to the 4th line.

Charles Matthews This is one case where database search does seem to support the proverb(s).

Diag.: Search region

I did a search for a region like this (marked points included), not anchored (so in any position along the side), and symmetrised for left-right reflection. Mostly this formation will arise as White capping Black's stone. The most common answer was Black at a (30%); then Black at b (15%), Black at c (13%), tenuki and White plays d (10%), Black plays e (8%).

In handicap go the answer at a is recommended, and it is also the common play in simple cases like this:

Diag.: Enclosure framework

Black does usually react with the marked stone or point.

I'd like to know more about the contact play and tenuki answers:
