Aji Keshi

[Diagram]
Diag.: aji keshi

Aji keshi is a move that unnecessarily removes one's own aji. As an example, the exchange of black 1 for white 2 in this diagram is a bad move. By playing this way, black loses the chance to later, when there might have come a black stone at A, peep at 2, followed by white 1 and black B. This loss of potential is much more important than the meager one point of territory that black gains.



Charles Matthews I'd like to amplify this.

[Diagram]
Diag.: A follow-up

You have first to imagine a follow-up play, such as the marked black stone. How did it get there? We can't be sure. It could for example be part of a complex fight spilling out from the top right corner.


[Diagram]
Diag.: Black takes advantage (gote)

This is one sequence that can follow. It is clearly good for Black, locally speaking.


[Diagram]
Diag.: Black takes advantage (sente)

This is another useful sequence for Black. In this case Black ends in sente. That could be an important difference, in heavy fighting.


[Diagram]
Diag.: White resists

So there seems to be a reason for White to play 2, looking to get sente by giving up this stone. Black 3 looks to connect Black up on the outside.


[Diagram]
Diag.: White resists, sequel

White 4 is indicated, to prevent that connection. But this leaves Black two good options: Black a White b with sente; or Black b White a Black c White d Black e for a squeeze and outside influence.

In summary, we have looked at just one black follow-up play round here - leading to at least two interesting variations from Black's perspective. The point I wish to make is that aji doesn't consist of a single sequence you wish to preserve as a future possibility. It is the whole complex of interesting things that might happen locally.
