Knight's move cap

W1 is a knight's move cap against black+circle. Compared to the ordinary cap at a this is more forceful. That doesn't imply that it is better; but this is one of the standard ideas of reduction play.

Passive?

B2 in reply is good for security; but in some contexts it will be a little too submissive.

Tenuki

Simply ignoring White's play invites W3, which is quite severe. One advantage the knight's move cap has is that this follow-up is stronger than in the case of the cap.

Strong resistance

Black should consider fighting harder with the contact play B2 and cross-cut B4. Now there will be a tough fight, and ladder relationships can be important.

White tries to settle

Therefore W3 is an option: this warikomi play makes it quite hard for Black to decide between a and b next.


There is a good example of this tactic in game 8 of the Kamakura jubango.
